Your own cells have protein signature directly dependent on the genetics. Everything that doesn’t match is attacked
yes, in fact our moral reasoning comes from the function of white blood cells and their extreme xenophobia - it is an important lesson to learn that foreign = bad, white = good … oh wait, hmmmmmmmmm
don’t give them nazis more ideas plz. they already have [gereric rationalization for their shit].
lol, you’re right - white blood cells justify bigotry is a much better argument than “my sky daddy said so!”
I thought it was that certain roaming immune cells are basically pretty interested in literally everything they encounter, but you’re own cells have chemicals cues that signal they are ok. And as soon as a they doesn’t get the ok signal, all hell breaks loose, signaling the home bade, calling for backup, etc.
But this can go wrong, with like bacteria or cancer trying to mimic the “ok” Signal.
If someone wants to add, please do, because although i’m a biologist i mostly remember that the immune system is way more complex than you’d think.
How do you explain autoimmune diseases then?
