Step I parasitic defense

[aspiringmd1015]

for parasitic defense, UW states that when a parsite comes into your body, igG and igE bind it up and via the FC receptor, ADCC occurs, fair enough. Then it also states in one of the other questions, that eosinophils, can act as APC's and phago the parasites and present them with mhc2 to helper t cells. So is it the second scenario, which call Th2 cells, which secrete igE to bind to the parsites and then il-5 for eosinophils, or a combo of both

I was not aware that eos could phago paras. Seems like a size issue to me.

i thought the same, but thats what UW said.

I didn't know eosinophils could be APCs.
