Gut microbiota and obesity, what comes first?
Dr. Thomas Greiner explains that the gut microbiota is influenced by your genes, who you're born from and you diet. However the gut microbiota is different between obese and lean patients. In the future studies may discover a right mixture of the bacteria and prevent obesity.

Microbiome: Translocation of a Gut Pathobiont Drives Autoimmunity
Martin Kriegel, M.D., Ph.D., Adjunct Assistant Professor of Immunobiology, at Yale School of Medicine, summarizes the main findings of a study from his laboratory published in the journal Science on March 9, 2018. After a brief introduction of the gut microbiome and its role in autoimmune diseases, he explains the study involving animal models of systemic lupus erythematosus and human samples from patients with lupus and autoimmune hepatitis. Dr. Kriegel highlights the new finding that a particular gut bacterium called E. gallinarum leaves the gut of autoimmune-prone animals and colonizes internal organs such as the lymph nodes and liver. Within these organs, the bacterium interacts with tissue and immune cells, which leads to autoimmune reactions linked with chronic organ damage. The organ damage and death of the animals could be prevented with an oral antibiotic or a vaccine against the bacterium given in the muscle. Mixing E. gallinarum, which was also found in patients’ livers, in culture dishes with human liver cells, led to similar inflammatory signals as seen in the animals.

Human Organs-on-Chips as replacements for animal testing with Donald Ingber
No more mice and no more human testing subjects! How great could life be? But, can Organs-on-a-Chip actually replace human organs? And what human organ functions can Organs-on-Chips be used to model? Plus, how effective are organs-on-chips at modeling human diseases and drug responses? Further, why is there a need to replace animal testing for drug development, should we care about mice? Can Organs-on-Chips be used for specific people, as in the making of personalised medicine?Organs-on-Chips are micro devices made out of living human cells and created with computer chip manufacturing techniques. Their applications are immense: they can be used for drug development, to investigate how organs work as well as to make personalised medicine. Donald Ingber, world leading biology engineer from the Wyss Institute for Biologically Inspired Engineering at Harvard will explain the recent advances in the engineering of multiple organ chips, including lung, intestine, kidney, and blood-brain barrier chips, as well as how they have been used to develop human disease models, co-culture living microbiome, and discover new therapeutics. Donald Ingber will also discuss recent efforts in joining all of these organ chips and forming a complete ‘human-body-on-chips’, therefore creating an instrument that can be used to study cellular responses to pharmaceuticals, chemicals and toxins.

Synthetic Biology: Programming Living Bacteria - Christopher Voigt
https://www.ibiology.org/bioengineering/genetic-circuits/ For synthetic biologists to engineer cells that can make complex chemicals or perform complex functions, they must be able to tell the cell which genes to turn on and at what time. To do this they build genetic circuits composed of a series of gates that respond to a specific input with a specific output. Voigt’s lab has developed a library of gates that can be interconnected, will function robustly and will not interfere with each other. In addition, they have developed software that lets users arrange the gates to form a circuit of their choice. The software provides DNA sequence encoding the circuit and the DNA can be synthesized and inserted into a cell. Voigt’s lab has successfully built and tested circuits in many cell types to make many products. Speaker Biography: Chris Voigt obtained his Bachelor's degree in chemical engineering from the University of Michigan and his PhD in biochemistry and biophysics from the California Institute of Technology. He was a postdoctoral researcher at the University of California, Berkeley and his first faculty position was at the University of California, San Francisco. In 2011, he joined the Department of Biological Engineering at the Massachusetts Institute of Technology as an associate professor. His lab is developing a programming language for cells to allow the regulation of complex cellular functions and their application to problems in biotechnology.

Paul E. Turner (Yale) 3: Phage Therapy
https://www.ibiology.org/microbiology/virus-ecology-evolution-virus-adaptation-phage-therapy/#part-3 Part 1: Introduction to Virus Ecology and Evolution: Dr. Paul Turner describes the fundamental biology of viruses, how they interact with their host organisms, and how they might have originally evolved long ago.   Part 2: Virus Adaptation to Environmental Change: Turner’s laboratory uses experimental evolution to study how viruses adapt to environmental changes.   Part 3: Phage Therapy: Turner provides an introduction to phage therapy, and how it can be improved by applying ‘evolution thinking’. Talk Overview: In his first lecture, Dr. Paul Turner describes the fundamental biology of viruses, how they interact with their host organisms, and how they might have originally evolved long ago. He provides an overview of the many reasons why viruses might be considered the most biologically successful inhabitants of earth, including their ability to rapidly reproduce, and adapt to environmental challenges. Turner explains how viruses have impacted human history, as well as earth’s history, due to their prevalent interactions with other species.        Viruses have an incredible capacity to adapt to environmental challenges, but sometimes, the environment constraints viral adaptation. Turner’s laboratory uses experimental evolution to study how viruses adapt to environmental changes (e.g. temperature changes), and the mechanisms by which viruses jump to novel host species. Turner’s work suggests that viruses with greater capacities to block the innate immune systems of their hosts, also have a greater likelihood of emerging on new host species. Also, he describes how virus adaptation to environmental change may be constraints by trade-offs: viruses can evolve either greater reproduction or greater survival, but not both simultaneously. Before antibiotics were discovered, scientists were using viruses of bacteria, bacteriophages, to treat bacterial infections in humans. Given the rise of antibiotic-resistant bacteria, scientists are revisiting the idea of using phage therapy to treat infections. In his third lecture, Turner provides an introduction to phage therapy, and how it can be improved by applying ‘evolution thinking’. His laboratory discovered phage OMKO1 that can treat multi-drug resistant bacteria in human patients while causing these bacteria to evolve greater sensitivity to antibiotics. Speaker Biography: Dr. Paul Turner is Professor of Ecology and Evolutionary Biology at Yale University, and holds an appointment in the Microbiology Program at Yale School of Medicine. His laboratory studies how viruses evolutionarily adapt to overcome environmental challenges, such as temperature changes or infection of novel host species. Turner received his bachelor’s degree in Biology from the University of Rochester in 1988, and completed his graduate studies in microbial ecology and evolution at Michigan State University in 1995.

How to green the world's deserts and reverse climate change | Allan Savory
"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

Stress Definition, Causes of Stress, Effects of Stress and How to Deal with Stress. Torii Labs
Stress Definition, Causes of Stress, Effects of Stress and How to Deal with Stress. Visit our website: https://toriilabs.com Subscribe to our Channel: http://www.enlaze.es/toriiyt Torii Labs - Plan Medicine Company - Herbal Elixirs What is stress Stress is a natural and essential response state that prepares the body for situations that are perceived to be of a critical or life-threatening nature. This fight or flight response, as it is commonly known, is part of the ancient reptilian brain, which was developed so that animals could successfully flee or combat the persistent dangers of that time. This physiological adaptation proved to be an essential component to their survival which is why it still pervades in our modern-day biological make-up. Most of us living in the developed world would agree that the environment we inhabit today is inherently less life threatening than in previous periods and yet most of us spend more time in this fight or flight state than ever before. ‘The annual stress survey commissioned by the American Psychological Association found that about 25% of Americans are experiencing high levels of stress (rating their stress level as 8 or more on a 10-point scale), while another 50% reported moderate levels of stress (a score of 4 to 7)’ (Harvard Medical School, March 18th 2018) and up to 90% of doctors visits in the US are stress related. Stress has changed drastically over time; we no longer need to prepare ourselves to escape the jaws of an apex predator but the same stress system is triggered by environmental toxins and perceived emotional stressors such as worrying about financial and job security. These new perceived threats are creating real ,prolonged, physiological stress responses, which are the direct cause for many of the non-communicable diseases such as heart disease, diabetes, Alzheimer’s, auto-immune disease and depression. What does it do to our body What happens to us physiologically when we are under stress? When our senses signal to our brain that we in a demanding or threatening situation the Amygdala communicates with the hypothalamus which sends a signal directly to our adrenal system to stimulate an immediate fight or flight response. If the threat is prolonged the Hypothalamic-Pituitary-Adrenal Axis (HPA) is activated and the pituitary gland secretes the hormone ACTH which in turn stimulates the adrenal glands to continue to produce the two main stress hormones, Cortisol and Adrenaline. When these hormones stay in our system for prolonged periods of time the body can be subjected to a number of deleterious and harmful effects. When under chronic stress blood flow is re-directed to organs that are essential for dealing with that stress, which leads to the neglect of other essential bodily systems. Chronic stress can have a damaging effect on our immune system and our gastrointestinal tract (G.I.T). How does stress affect our health Stress hormones called CRF’s can cause inflammation in the gut and affect the diversity and health of the microbiome in our intestinal tract. Research in mice has found that exposure to stress led to an overgrowth of certain types of bacteria while simultaneously reducing microbial diversity in the large intestine of the stressed mice. Due to our strong gut-brain axis, a stressed gut can cause depression and other psychological disorders by reducing essential neurotransmitters such as dopamine and serotonin, of which 95% are produced in our large intestinal tract. As the HPA system becomes depleted from excessive and prolonged activation we are unable to produce healthy amounts of stress hormones which is essential to feeling energized and focused. This is typically known as adrenal fatigue. In conclusion – stress is something we have to address on a daily basis. When managed properly it facilities a positive physiological response that helps us response effectively to the demands and threats that we encounter. However, if the fight or flight response is prolonged, usually through emotionally driven perceived threats, then the body and mind can experience a multitude of diseases that deplete our well-being and vitality.

Health lies in healthy circadian habits | Satchin Panda | TEDxBeaconStreet
Every organ and even every cell in our body has circadian or 24 h clock. Circadian clocks turn on and off thousands of genes at the right time of the day or night. These rhythms work together to maintain healthy balance of brain chemicals, hormones, and nutrients. When our rhythms break down we are more likely to suffer from a wide range of diseases from depression to cancer. We can tune our daily habits of eating, sleeping or getting the right amount of light to sustain our circadian rhythms. Healthy rhythms nurture healthy body and healthy mind. Dr. Satchidananda Panda, a professor at the Salk Institute for Biological Studies in La Jolla, California. Satchin’s work deals specifically with the timing of food and it’s relationship with our biological clocks governed by circadian rhythm and also the circadian rhythm in general. Professor Panda explores the genes, molecules and cells that keep the whole body on the same circadian clock. A section of the hypothalamus called the suprachiasmatic nucleus (SCN) lies at the center of the body’s master clock and gets input directly from light sensors in the eyes, keeping the rest of the body on schedule. Panda discovered how these light sensors work, as well as how cellular timekeepers in other parts of the body function. He also uncovered a novel blue light sensor in the retina that measures ambient light level and sets the time to go to sleep and wake up every day. In the process of exploring how the liver’s daily cycles work, Panda found that mice which eat within a set amount of time (12 hours) resulted in slimmer, healthier mice than those who ate the same number of calories in a larger window of time, showing that when one eats may be as important as what one eats. If the benefits of this “12-hour diet” hold true in humans, it could have profound impacts on treating overeating disorders, diabetes and obesity. The circadian clock, he found, even mediates the immune system. Mice with a crucial circadian molecule missing had higher levels of inflammation in their bodies than other mice, suggesting that genes and molecules involved in the circadian clock could be drug targets for conditions linked to inflammation, such as infections or cancer.

Roland Griffiths, Ph.D. on Psilocybin,  Psychedelic Therapies & Mystical Experiences
Dr. Roland R. Griffiths is a clinical pharmacologist at Johns Hopkins. Dr. Griffiths has been researching mood-altering compounds for over 40 years, has published over 360 times, and started the psilocybin research program at Johns Hopkins nearly 2 decades ago. In this 1-hour and 15-minute podcast, we discuss… • 00:01:03 - the broader story of Dr. Griffiths 40 years of mood-altering drug research, including what got him started and how taking up a meditation practice ultimately influenced the eventual focuses of his research. • 00:02:22 - the effect psilocybin has had in clinical trials in eliciting so-called mystical experiences that can act as a long-term catalyst for meaningful spiritual change and is amenable to being reproduced and clinically studied in a prospective manner. • 00:03:45 - what distinguishes psilocybin from other drugs, particularly when reflecting backward on the experience months afterward. • 00:05:11 - the process by which Dr. Griffiths and his team create an appropriate “setting” and facilitate feelings of safety for those participating in his trials. • 00:06:42 - the elusive fundamental nature of a classical psychedelic experience whereby people often simultaneously describe the experience as ineffable (indescribable) but yet also often assign it a truth value that may even exceed that of everyday consensus reality. • 00:07:36 - a description of the core features of a classical mystical experience that overlap with those found in a mystical experience induced by psilocybin. • 00:08:58 - the qualities of the experience that Dr. Griffiths believes to most underlie the “reorganizational” potential it can have. • 00:10:55 - the interesting potential areas for scientific exploration that the reproducibility of the psilocybin experience makes the substance amenable to. • 00:11:25 - the promise psilocybin has shown as an effective therapeutic for anxiety and depression in patients with life-threatening cancer and also treatment-resistant depression in otherwise healthy patients (00:18:46). • 00:13:04 - the lack of rigor in the very early trials on these compounds and the way in which cultural stigma surrounding psychedelic drugs ultimately played a role in impeding real, substantive clinical research for decades afterward. • 00:16:31 - the long-term resilience of the antidepressant and anxiolytic effect, lasting six months and possibly even longer. • 00:21:01 - the effect psilocybin has demonstrated in animal studies to increase hippocampal neurogenesis and enhance extinction of trace fear conditioning. • 00:23:07 - the somewhat unintuitive neurobiological mechanism that may tie together some of the antidepressant properties of both psilocybin and ketamine, an anesthetic currently being studied as a rapid-onset antidepressant. • 00:25:16 - whether or not the mystical subjective experiences are necessary for drugs like psilocybin to exert their antidepressant or anxiolytic effects. • 00:26:43 - what the default mode network is and what its pattern of activity is in depression, long-term meditators, and after the acute use of psilocybin. • 00:32:16 - the hard problem of consciousness. • 00:37:26 - the challenge of finding the neurological correlates to match the phenomenology of individual’s subjective experiences. • 00:38:16 - the promise psilocybin has shown in a small trial on smoking cessation where 60% of the treatment group were still abstinent a year afterward and plans Dr. Griffiths has to expand this area of research • 00:41:10 - the possibility that the “reorganizational nature” of these experiences may open up new avenues as trials continue to try to embed the experience within different therapeutic contexts. • 00:44:02 - the roadmap to FDA approval for use of psilocybin as a medication, particularly in the context of cancer-associated depression and anxiety. • 00:45:05 - the risks inherent in taking psilocybin and the frequency of self-reported negative experiences in the general population. • 00:47:22 - the criteria Dr. Griffiths and his colleagues use when screening for volunteers to participate in his studies involving psilocybin. • 00:49:21 - the inability for clinicians to predict who is at risk of having challenging experiences defined by fear and anxiety (“bad trip”) and whether or not it is desirable, in terms of achieving a therapeutic outcome, to prevent these types of experiences altogether or not. • 00:51:43 - the sort of dosages used in the trials. • 00:54:45 - the clever ways devised by Dr. Griffiths to placebo control trials where expectation itself can affect outcome. • 00:57:45 - some of the interesting anecdotes gleaned from Dr. Griffiths’ working with long-term meditators participating in the psilocybin trial. • 01:05:13 - a brief discussion about some of the other psychedelics besides psilocybin, such as salvia divinorum and DMT (at 01:10:24). • 01:12:08 - the historical indigenous use of psychedelics in various cultures spread throughout the world.

Effector cells, tagged green, seem to fade as they detect chemokines and move inward, past the surfa
The white blood cells that fight disease and help our bodies heal are directed to sites of infection or injury by 'exit signs' - chemical signals that tell them where to pass through the blood vessel walls and into the underlying tissue. New research at the Weizmann Institute, which appeared in Nature Immunology online, shows how the cells lining blood vessel walls may act as 'selectors' by hiding the signals where only certain 'educated' white blood cells will find them.

Offspring Obesity Study
Researchers at the University of Cincinnati released a new study which says how women lose weight could impact the long-term health of babies. Doctor Randy Seeley was the principal investigator in this study. His team here conducted lab studies on rodents to find out what happens to the health of their offspring when mom has obesity or bariatric surgery to lose weight. He says, in people, we do know babies born to moms who are obese or who have diabetes tend to have a greater chance of these same problems later in life. Dr. Randy Seeley, U.C. "Meaning, they are more likely to become obese or have diabetes themselves, if mom was obese." So, when it comes to losing weight, you were looking specifically at one type of surgery what was that? "So the study was to use rodent models, where we make the mom rats obese through a high fat diet to consume, and then we would do a surgery called a vertical sleeve gastrectomy." As this animation, courtesy of you -tube shows, a vertical sleeve gastrectomy makes the stomach about the size of a banana. But Doctor Seeley points out that in the process it also alters hunger hormones and signals that help mom lose weight, but in his studies the same was not true for their offspring. In fact, they had more risks for being overweight and getting diabetes later in life. "Those same signals that might help mom get better, might also in fact put offspring at some peril, in terms of the risk for obesity and diabetes." "So, I want to be careful here, the take home message here is what?" "The take home message for moms is exactly as it was before, eating well and exercising during pregnancy is a way to limit the potential of what's going to happen to future generations." We can't say yet, that the same is true without this formula. Researchers at the University of Cincinnati say they do now plan to study other types of obesity surgery and see if they get the same results. As always, if you are considering obesity surgery and want to have children following this decision make sure you talk to your own doctor.

What is FLUORINE DEFICIENCY? What does FLUORINE DEFICIENCY mean? FLUORINE DEFICIENCY meaning - FLUORINE DEFICIENCY definition - FLUORINE DEFICIENCY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Fluoride or fluorine deficiency is a disorder which may cause increased dental caries (or tooth decay, is the breakdown of dental tissues by the acidic products released by the "bacterial fermentation of dietary carbohydrates.") and possibly osteoporosis (a bone disorder which leads to a decrease in bone mass, and an increase in bone fragility), due to a lack of fluoride in the diet; however, there are anti-osteoporotic functional food ingredients that can help decrease the risk of osteoporosis fractures. In terms of dietary sources, fish and tea are considered natural sources of fluoride, as well as tap water that has been fluoridated. The extent to which the condition truly exists, and its relationship to fluoride poisoning has given rise to some controversy. Fluorine is not considered to be an essential nutrient, but the importance of fluorides for preventing tooth decay is well-recognized, although the effect is predominantly topical. Prior to 1981, the effect of fluorides was thought to be largely systemic and preeruptive, requiring ingestion. Fluoride is considered essential in the development and maintenance of teeth by the American Dental Hygienists' Association. Fluoride is also essential as it incorporates into the teeth to form and harden teeth enamels so that the teeth are more acid resistant as well as more resistant to cavity forming bacteria. Caries-inhibiting effects of fluoride were first seen in 1902 when fluoride in high concentrations was found to stain teeth and prevent tooth decay. Fluoride salts, particularly sodium fluoride (NaF), are used in the treatment and prevention of osteoporosis. Symptoms such as fractured hips in the elderly or brittle and weak bones are caused due to fluorine deficiency in the body. Fluoride stimulates bone formation and increases bone density, however bone with excess fluoride content has an abnormal structure resulting in increased fragility. Thus fluoride therapy results in large increases in bone mineral density but the effect on fracture rates, while positive, is small. Disputes over the essentiality of fluorine date back to the 19th century, when fluorine was observed in teeth and bones. In 1973 a trial found reduced reproduction in mice fed fluorine-deficient diets, but a subsequent investigation determined that this was due to reduced iron absorption. Fluoride has proven to be an essential element with preventative and protective properties. Fluoride is capable of combating and working against tooth decay and increases resistance to the "demineralisation of tooth enamel during attack by acidic bacterias". While essential for all individuals, it is significant for children, as when ingested, the fluoride is incorporated into their developing enamel. This in turn causes their teeth to become less prone to decay. Therefore, a relationship can be formulated, in that the more fluoride entering the body, the overall decline in the rate of decay. Fluorine is one of the most common and rich elements to exist within the Earth's crust. It is most commonly found in its ion form, or additionally as inorganic or organic fluorides. Fluoride supplements were first recognised and highly suggested by health professionals, in areas where the practice of fluoridating water was not accepted. Such mechanisms are recommended for individuals, primarily children (whom of which are at a greater risk of caries) in low-fluoride areas. Supplements can be in various forms including tablets, drops or lozenges, and have proven to greatly decrease the case and rate of tooth decay.

Susan Lindquist (Whitehead, MIT / HHMI) 3: Prions: Protein Elements of Genetic Diversity
https://www.ibiology.org/biochemistry/prions/#part-4 In Part 1a, Dr. Lindquist explains the problem of protein folding. Proteins leave the ribosome as long, linear chains of amino acids but they need to fold into complex three dimensional shapes in the extremely crowded environment of the cytoplasm. Since protein misfolding can be disastrous for cells, proteins known as heat shock proteins (HSPs) have evolved to facilitate proper protein folding. Lindquist explains that sometimes the heat shock response becomes unbalanced resulting in human disease. In the case of cancer, HSPs help cancer cells survive many stresses that would typically kill them. In contrast, many neurodegenerative diseases are a result of protein misfolding and aggregation suggesting that, in these diseases, HSPs are not activated when they should be. Yeast have many of the same cellular processes as humans including a stress response to aid in protein folding and prevent protein aggregation. In Part 1b, Lindquist describes how genetic screens in yeast helped scientists identify mutations that increased the formation of aggregates similar to those found in neurodegenerative diseases. Furthermore a screen in yeast of ~500,000 chemicals identified a number of compounds that prevented protein aggregation. Results from both experiments have since been validated in mice and human neuronal models. When cells undergo stress, the expression of HSPs increases. In Part 2, Lindquist explains that while most HSPs are expressed only as needed, Hsp90 is expressed in excess. This “buffer” of Hsp90 facilitates the folding of some mutant proteins (such as v-src) that would usually misfold and be degraded by the cell. Thus, Hsp90 potentiates the impact of these mutations. Interestingly, the Hsp90 “buffer” can also act to hide or suppress the impact of other mutations. These “hidden” mutations are found when cells are stressed reducing the pool of available Hsp90. Thus, Hsp90 provides a plausible mechanism for allowing genetic diversity and fluctuating environments to fuel the pace of evolutionary change. In her last talk, Lindquist focuses on prion proteins. Prions are perhaps best known as the infectious agents in diseases such as mad cow disease. However, Lindquist argues that there are many great things about prions too. They provide a protein-based mechanism of inheritance that allows organisms to develop new traits, quickly and reversibly, and thereby adapt to new environments. Working in yeast, Lindquist and her colleagues were able to identify numerous prion-like proteins that are induced at different levels, depending on the temperature, pH or presence of bacteria. Expression of prions caused heritable, phenotypic changes in the yeast demonstrating that prions are another mechanism by which environmental changes can induce new traits that can be passed onto progeny. As Lindquist says, perhaps it is time to give Lamarck back his dignity. Speaker Biography: Susan Lindquist is a member and former Director of the Whitehead Institute for Biomedical Research. She is also a Howard Hughes Medical Institute Investigator and Professor of Biology at the Massachusetts Institute of Technology. She received her Ph.D. in biology from Harvard and was a postdoctoral fellow of the American Cancer Society. Lindquist was on the faculty of the University of Chicago for over 20 years before moving to MIT in 2001. A pioneer in the study of protein folding, Lindquist found that the chaperone Hsp90 potentiates and buffers the effects of genetic variation, fueling evolutionary mechanisms as diverse as malignant transformation and the emergence of drug resistance. Her work established the molecular basis for protein-based mechanisms of inheritance and she demonstrated that Hsp90 and prions each provide distinct but feasible mechanisms of Lamarckian inheritance. Dr. Lindquist is an elected member of the National Academy of Sciences, the Academy of Medicine and the Royal Society. Her honors also include the Dickson Prize in Medicine, the Otto-Warburg Prize, the Genetics Society of America Medal, the FASEB Excellence in Science Award, the E.B. Wilson Medal, the Vanderbilt Prize for Women’s Excellence in Science and Mentorship and the National Medal of Science.

Ira Mellman (Genentech) Part 2: Antigen Presentation and Dendritic Cells
https://www.ibiology.org/immunology/immune-response/#part-2 The immune response integrates two distinct systems of innate and adaptive immunity discovered over 100 years ago. Linking these two arms of the immune response is the task of a comparatively recently identified cell type, the dendritic cell. Dendritic cells have the capacity to detect the conserved microbial products that activate cells of the innate immune response and capture the dramatically wider diversity of microbial antigens to prime antibody and T cell responses characteristic of adaptive immunity. The unique capacity of dendritic cells for antigen processing and presentation reflects a series of remarkable specializations of basic principles of cell biology.

LS1C - Matter and Energy Flow in Organisms
Life Science Disciplinary Core Idea 1C: Organization of Matter and Energy Flow in Organisms Sustaining life requires substantial energy and matter inputs. The complex struc- tural organization of organisms accommodates the capture, transformation, trans- port, release, and elimination of the matter and energy needed to sustain them. As matter and energy flow through different organizational levels—cells, tissues, organs, organisms, populations, communities, and ecosystems—of living systems, chemical elements are recombined in different ways to form different products. The result of these chemical reactions is that energy is transferred from one system of interacting molecules to another.

Human monoclonal antibodies as therapeutics against viral and bacterial infections
Harnessing nature’s gift: human monoclonal antibodies as therapeutics against viral and bacterial infections Air date: Wednesday, April 27, 2016, 3:00:00 PM Category: WALS - Wednesday Afternoon Lectures Runtime: 01:07:09 Description: NIH Director’s Wednesday Afternoon Lecture Series Antibodies are potent components of the human immune system and show great potential as therapeutics for the treatment of infectious diseases. In this lecture, Dr. Tan will provide two examples on how the antimicrobial discovery teams at Genentech isolated and engineered human antibodies to treat viral and bacterial infections. First, using an innovative in vivo human-plasmablast enrichment technique, his laboratory discovered antibodies that neutralize all seasonal and pandemic influenza A viruses. These antibodies bind hemagglutinins (HA), locking the HA in the pre-fusion conformations and prevent fusion between the viral membrane and host endosome. Efficacy studies in animal and human challenge models of influenza infections have demonstrated that these antibodies have strong antiviral activity and the potential to be used as therapeutics for the treatment of severe influenza infections. Second, Dr. Tan will discuss the development of an antibody-antibiotic conjugate (AAC) for the treatment of severe Staphylococcus aureus infections. S. aureus can survive within multiple human cell types. The fact that bacteria within the intracellular environment are protected from antibiotics provides a compelling explanation for clinical failures of conventional antibiotic therapy. The Tan lab confirms that the intracellular reservoirs of S. aureus comprise a virulent subset of bacteria that can establish infection even in the presence of vancomycin. This finding suggests that AAC is superior to vancomycin for treatment of bacteremia.
