Jeff Mold @jeffmold.bsky.social · 20hBut I would love someone to prove me wrong that T cells can themselves kill and maintain a complete destruction of all hair follicles in a human body for a sustained period of time with no obvious overt inflammatory consequences beyond hair loss. I concede it is possible, just feels unlikely? 000
Jeff Mold @jeffmold.bsky.social · 20hThis is neat - but can you achieve total hair loss with this system as you see in Alopecia Totalis? I have always been wondering if you can get enough of a CD8 T cell response going to cover the entire body including eyelashes?

Jeff Mold @jeffmold.bsky.social · 18/08/2026Sometimes I feel like we fail as immunologists to clearly portray activation markers like PD1 as that rather than imply it always means exhaustion and transient lymphopenia after an infection as reorganization of cells to tissues rather than “depletion”. 240
