Plants detect bacterial endotoxin in similar process to mammals

Similar to humans and animals, plants possess an innate immune system that protects them from invading pathogens. Molecular structures that only occur in pathogens enable their recognition and trigger the immune response. Lipopolysaccharide (endotoxin) is one such substance, occurring in the outer membrane of certain bacteria. Show More Summary

A Biological Basis for Chronic-Fatigue Syndrome

New research shows that sufferers have differences in their immune systems, a finding the authors hope will lend some legitimacy to the still-mysterious conditon.

Mitochondrial 'shield' that helps cancer cells survive identified

Why can cancer cells be so resilient, even when faced with the onslaught of nearly toxic drug cocktails, radiation, and even our own immune system? A new research report appearing in the March 2015 issue of The FASEB Journal, shows that...Show More Summary

Mitochondrial 'shield' that helps cancer cells survive identified

Scientists have moved closer to understanding why cancer cells can be so resilient, even when faced with the onslaught of nearly toxic drug cocktails, radiation, and even our own immune systems. A new research report shows that intermediate...Show More Summary

Robust evidence that chronic fatigue syndrome is a biological illness

Researchers have identified distinct immune changes in patients diagnosed with chronic fatigue syndrome, known medically as myalgic encephalomyelitis or systemic exertion intolerance disease. The findings could help improve diagnosis...Show More Summary

Early signs in young children predict type 1 diabetes

It is possible to predict the development of type 1 diabetes, new research indicates. By measuring the presence of autoantibodies in the blood, it is possible to detect whether the immune system has begun to break down the body’s own insulin cells.

Why Natural Selection Hasn’t Trashed Mental Illness

Understanding the whys and what-fors of any sort of disease is a deep enough undertakingan immune system trying to tear its host apart? Rapid-fire assembly lines of cancerous tissue?but mental illness puts the whole nature of the question in even more extreme relief. Show More Summary

Yoga For Athletes

It is common knowledge now that the health benefits of yoga are both numerous and tremendous. In addition to improving flexibility and mobility throughout the entire body, practicing yoga regularly strengthens your immune system. It reduces stress and lowers blood pressure. Show More Summary

Breastfeeding helps shape immune system early in life

A new paper says that breastfeeding and other factors influence a baby's immune system development and susceptibility to allergies and asthma by what's in their gut. The findings, from a series of studies further advance the so-called...Show More Summary

Breastfeeding, Other Factors Help Shape Immune System Early in Life

Henry Ford Hospital researchers say that breastfeeding and other factors influence a baby's immune system development and susceptibility to allergies and asthma by what's in their gut.

Virus-cutting enzyme helps bacteria remember a threat

Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destroy it when it shows up again.

Health Benefits Of Diet And Exercise May Be Chemically/Lazily Obtainable

last monthGenres / Sci Fi : io9

Everybody knows the human immune system will respond enthusiastically to exercise and healthy eating. But is there a way to get those benefits, which include enhancing our bodies' abilities to suppress certain kinds of inflammation, without, y'know, sweating or starving? Read more...

New test to predict effectiveness of cancer vaccines

Many therapeutic cancer vaccines that are currently being developed are designed to direct the immune system against altered cancer-cell proteins. However, these vaccines can only be effective if the tumor cells present the altered protein to the immune system in a perfectly matching shape. Show More Summary

New Tattoo Removal Cream Exploits Immune System

A university researcher says he’s developing a cream that could remove tattoos cheaply and without pain. A tattoo doesn’t work simply by burying ink deep enough  (in the dermis) that it remains in place as the skin regenerates. Instead...Show More Summary

New test to predict the effectiveness of cancer vaccines

Cancer vaccines are designed to turn the body's own immune system specifically against tumor cells. Particularly promising are vaccines that are directed against so-called neoantigens: These are proteins that have undergone a genetic mutation in tumor cells and, therefore, differ from their counterparts in healthy cells.

Why Vaccines Work

last monthHumor : Neatorama

(YouTube link) What do scurvy and measles have in common? They are diseases we can defeat, as long as we take the proper steps to prevent them. This video from It’s OK To Be Smart goes over the basics of the immune system and how vaccines affect them. Show More Summary

DNA-damage causes immune reaction, inflammation; linked to cancer development

For the first time scientists show the importance of DNA damage in fine tuning of our innate immune system and hence the ability to mount the optimal inflammatory response to infections and other biological dangers.

Watch white blood cells swarm and attack a parasite

last monthTechnology / Gadgets : Gizmodo

The human body is such a magnificent thing. Just check out this video that shows how our immune system works. When a parasite finds its way inside a place where it clearly shouldn't be, white blood cells immediately start rushing to the rescue. It only takes a few seconds for the parasite to get swallowed.

An Animated Video Explaining the History and the Science Behind Common Vaccinations

last monthHumor : Laughing Squid

In “Why Vaccines Work” by It’s Okay To Be Smart, host Joe Hanson explains the history of vaccines using scurvy as an example, the science behind vaccines and how they work. Our immune system is on constant alert against germy baddies, with millions of white blood cells each on the lookout for specific infections. When […]

Anti-inflammatory mechanism of dieting and fasting revealed

Researchers have found that a compound produced by the body when dieting or fasting can block a part of the immune system involved in several inflammatory disorders such as type 2 diabetes, atherosclerosis, and Alzheimer's disease.
