Major Histocompatibility Complex Abounds

the unsung song of antigen presenting cells


You put your life on the line
to present these foreign signs
calling out the truth to cells
through MHC confines
attacking substances that invade our lives
you shout victory to the world
when you help activate the dormant
your importance becomes unfurled
so faithful regardless of the infection
or what an immunologist injects
you don't judge, you just display
on major histocompatibility complex

So, don't let these peptides you ingest
lead you far astray
you do things I don't even do
like recycle every day!
There's no need to feel alone
how you process is not arcane
any cell worth its nucleus presents except
with an added beta-microglobulin chain
so, don't let them call you snitch
because you know it isn't true
proper antigen response is something
important we owe to you!
