Study finds signs of IgA antibodies in the cerebrospinal fluid of patients with multiple sclerosis during a flare-up of the disease, but not when the patients are in remission. The findings suggest gut immune cells are involved in relapse episodes of multiple sclerosis.
Study investigates whether overactive immune cells that produce neutrophil extracellular traps (NETs) are responsible for more severe and lethal cases of coronavirus.
Using CRISPR gene editing, researchers mapped important genes for helping T helper cells. The findings could help generate new treatments to activate the immune system against infection and to attack tumor cells.
