How are memory B cells activated?
Memory B Cells Can Be Activated by Antigen after Adoptive Transfer into Mice Lacking T Lymphocytes.
What are the stages of B cell activation?
B cell development takes place in a series of six main stages. First, they start as common lymphoid progenitor cells, which become early pro-B cells, then late pro-B cells, next large pre-B cells, then small pre-B cells, and finally, immature B cells.
What are the steps of B cell activation and differentiation?
The differentiation of a stem cell into a mature B cell can be subdivided into five steps: early pro-B cells, late pro-B cell stage, pre-B cell stage, immature B cells, and mature B cells. Each differentiation step appears to be regulated by co-receptor and cytokines.
B-cell activation by many antigens, especially monomeric proteins, requires both binding of the antigen by the B-cell surface immunoglobulin—the B-cell receptor—and interaction of the B cell with antigen-specific helper T cells.
