"Stress-induced sympathetic hyperactivation drives hair follicle necrosis to trigger autoimmunity" spkl.io/63326Ad0f6 Ya-Chieh Hsu & colleagues @cp-cell.bsky.social
Acute stress causes immediate hair follicle necrosis and hair loss via sympathetic nerves, which in turn activates and expand s autoreactive CD8 ⁺ T cells targeting hair follicles. Thus, a single stress event not only causes immediate tissue damage but also predisposes the tissue to future autoimmune attack.
