When do B-cells differentiate?

Dec 28th, 2014

Once a B cell encounters its cognate antigen and receives an additional signal from a T helper cell, it can further differentiate into one of the two types of B cells: plasma B cells and memory B cells. The B cell may either become one of these cell types directly or undergo an intermediate differentiation step, the germinal center reaction, where the B cell will hypermutate the variable region of its immunoglobulin gene ("somatic hypermutation") and possibly undergo class switching. Other functions for B cells include antigen presentation, cytokine production, and lymphoid tissue organization.
