how does the Immune system recognize hair or finger nails as it's own?

>>	Anonymous Sun Apr 21 20:57:50 2019 No.10578956 >>10578951 I would assume so? Never really put much thought into it but I believe that basically every cell in the body would have antigens so the immune system doesn't target it

>>	Anonymous Sun Apr 21 22:36:04 2019 No.10579191 >>10578965 that's cool but prob also makes having an ingrown hair a lot shittier and more painful

>>	Anonymous Mon Apr 22 07:42:21 2019 No.10580084 >>10578920 Keratin and zinc. Zinc acts like a galvanization marker in the keratin. The body cannot oxidize it or sense anything volatile so it builds around it, just like titanium implants.

>>	Anonymous Mon Apr 22 11:55:01 2019 No.10580659 >>10578965 id assume its just because the cells intrude into an area that they're not meant to be and create pressure and pain

>>	Anonymous Mon Apr 22 12:05:18 2019 No.10580683 >>10580659 I'd assume it's because dead keratin cells are no longer part of your living organism, and are seen as foreign intruders when they manage to get inside.
