Pregunta:

How are B cells activated?

Autor: Shay 1vcc



Respuesta:

Initiates proliferation and differentiation to prepare for interaction with helper T cells Maximal B cell activation is accomplished by multivalent antigen that crosslinks many receptors + engagement of CR2 and TLR. Protein antigens do not have these features, but they induce interactions with helper Th cells by presenting antigen on MHCII receptors.
