Why we do not constantly get ill despite viruses, bacteria New research breaks with existing knowledge about how our immune system works. The new experiments have shown how the body mobilizes a hitherto unknown defense against viruses and bacteria. This also explains why we do not constantly get ill despite the viruses around us.
Immune system affects gut bacteria evolution Researchers have discovered that when the immune system of the host is compromised, the composition of the gut bacteria changes, and the pace and predictability of the process of adaptation of these bacteria are affected. This study suggests that the treatment of intestinal pathologies that result from impaired immune system, such as the inflammatory bowel disease, may require therapies based on personalized medicine.
Studying stonefish venom may help combat transplant rejection The X-ray crystal structure of the lethal factor present in stonefish venom has been solved by researchers. The discovery has provided unexpected insight into a crucial human immune response that is responsible for the failure of up to 30 percent of bone marrow transplant therapies for treating leukemia.
In pursuit of HIV vaccine, scientists shed light on antibody origins Scientists have tracked how a family of HIV-fighting antibodies develops over time. The research shows how a future vaccine might trigger the immune system to produce these antibodies more effectively.
