Okay, i have a few questions:
1: Do macrophhages present antigens on MHC 2 or the MHC 1?
2: How do phagocytes actually recognise pathogens? They don't have antibodies or anything so how do they recognise? Is it their MHC 2 ?
3: I had a question asking to identify a cell that acts as a "receptor" for a particular bacteria, so i said thhe T helper cell is thhat correct?
4: after that question, there was another question asking to explain another way that bacteria could be recognised FROM other cells, this confused me, i imagined it would be how T helper cell (that i gave previously) would recognise the bacteria through another cell, such as a macrophage presenting the bacteria's antigen. Would that be right? I was gonna write how a different cell would recognise the bacteria, such as how a B cell will hhave it's antibody bind to the antigen, but i didnt do that because the question said "From other cells" not "by other cells"
I dont know, it confused me a lot.
