Coordination of mitochondrial and lysosomal homeostasis mitigates muscle atrophy during aging
“our data allow us to propose a new adaptive mechanism involving the mitophagy protein BNIP3, which links mitochondrial and lysosomal homeostasis with inflammation and is key to maintaining muscle health during aging.”
Far-UVC (222 nm) efficiently inactivates an airborne pathogen in a room-sized chamber
“A new type of ultraviolet light that is safe for people took less than five minutes to reduce the level of indoor airborne microbes by more than 98%, a joint study by scientists at Columbia University Vagelos College of Physicians and Surgeons and in the U.K. has found. Even as microbes continued to be sprayed […]
Study identifies how Epstein-Barr virus triggers multiple sclerosis
“Part of the EBV protein mimics your own host protein—in this case, GlialCAM, found in the insulating sheath on nerves,” said William Robinson, MD, Ph.D., professor of immunology and rheumatology at Stanford. “This means that when the immune system attacks EBV to clear the virus, it also ends up targeting GlialCAM in the myelin.”
New way viruses trigger autoimmunity discovered
“…The researchers found that the mice with gastritis had developed antibodies against proteins on stomach cells. But they also had developed antibodies against a wide array of normal proteins associated with other autoimmune conditions. In addition, they had many T cells that targeted the body’s own normal proteins, and other changes to the T cell […]
Gut bacteria linked to immune suppression in pancreatic cancer: study
“Lactobacillus—a type of bacteria thought to promote gut health—can alter the function of immune cells called macrophages in the pancreatic tumor environment and spur cancer growth, the researchers found”
