A newly found genetic master switch helps your immune cells protect organs
Scientists have identified a genetic master switch called ETS1 that controls how specialized immune cells move from the bloodstream into vital organs to provide localized protection against pathogens.
Researchers recently identified a genetic master switch named ETS1 that dictates how T cells transition into permanent residents within our organs. While most immune cells circulate through the blood, these resident cells stay behind to act as local sentinels in tissues like the skin and lungs.
