study examines effects of spaceflight on immune system




getting sick isn't fun for anyone, but it could be especially taxing for crew members aboard the international space station. protecting crew health is important as nasa prepares for long duration, deep-space missions. functional immune, a new investigation taking place in the orbiting laboratory, s...



the hlf-gene controls the generation of our long-term immune system




a research group at lund university in sweden has found that when the hlf (hepatic leukemia factor) gene -which is expressed in immature blood cells - does not shut down on time, we are unable to develop a functional long-term immune system. this could be a very early stage of leukemia.blood stem ce...

researchers reprogram immune cells to treat psoriasis and more




a new study details the successful reprogramming of certain immune cells that could lead to treatments for autoimmune diseases like psoriasis. the work was performed by researchers with the gladstone institutes, and it is made possible by a ‘small-molecule drug’ that essentially converts immune ...



scientists light the way for immune system to attack cancer




the science behind harnessing the immune system to fight cancer is complicated, but a university of rochester medical center laboratory discovered a simple, practical way to use light and optics to steer killer immune cells toward tumors. in a study published by the online journal nature communicati...



new finding affecting immune reconstitution related to b cells




researchers from the children's center for cancer and blood diseases at children's hospital los angeles examined the mechanisms of b cell immune reconstitution in pediatric patients who had undergone bone marrow transplantation and discovered a disruption in the maturation of b cells - critical to t...

mum's immune response could trigger social deficits for kids with autism




the retrospective cohort study of 220 australian children, conducted between 2011-2014, indicates that a "an immune-mediated subtype" of autism driven by the body's inflammatory and immunological systems may be pivotal, according to the university of sydney's professor adam guastella.autism spectrum...



scientists discover how obesity stops 'guardian immune cells' from doing their j




scientists have uncovered the physiological mechanics underlying inflammation and obesity by tracking the actions of 'guardian immune cells' in response to changes in diet. they believe their work may herald a new era of research now that they have new therapeutic targets to prevent and control obes...



is functional programming better for your startup?




even though functional programming has been around for over half a century, it has never gained the kind of popularity anywhere near what imperative programming (e.g. c, java) achieved. nevertheless, it seems to have been increasingly talked about in the technology world.so why is functional program...



fish provide insight into the evolution of the immune system




new research from the university of east anglia (uea), uk, and dalhousie university, canada, reveals how immune systems can evolve resistance to parasites.



new limits to functional portion of human genome reported




an evolutionary biologist at the university of houston has published new calculations that indicate no more than 25 percent of the human genome is functional. that is in stark contrast to suggestions by scientists with the encode project that as much as 80 percent of the genome is functional.



gut bacteria may make or break your chances of cancer treatment working

viruses up their game in arms race with immune system




in a classic example of the evolutionary arms race between a host and a pathogen, the myxoma virus—introduced to control the rabbit population in australia in 1950—has developed a novel and deadly ability to suppress the immune response of its host rabbits. new research shows that viruses collec...



lab mice may not be effective models for immunology research




the findings have implications for all aspects of medical and scientific research because laboratory mice underpin studies whose results have a transformative effect on human and animal lives through vaccination and other immune-based therapies.professor mark viney and colleagues from the university...

subduing the rebellion: unmasking rogue cells in the immune system




the immune system is a formidable defense against microbial intruders, identifying and eliminating the threats through an extremely intricate and adaptable network of specialized cells. however, a system of such mind-boggling complexity is also prone to misfire. due to genetic mutations for example,...



how zika virus tricks pregnant women's immune systems




birth defects caused by the zika virus can occur at any point during pregnancy, but scientists now know that the dangers of contracting zika are especially heightened during the first trimester. a new study suggests that early pregnancy is such a risky time because the virus tricks a pregnant woman...



new way found to boost immunity in fight cancer and infections




an international research team led by université de montréal medical professor christopher rudd, director of research in immunology and cell therapy at maisonneuve-rosemont hospital research centre, has identified a key new mechanism that regulates the ability of t-cells of the immune system to re...
