摘要:
B lymphocytes, like macrophages and dendritic cells, can present antigen to CD4+ T cells. Antigen presentation by B cells is essential for the generation of an in vivo T cell dependent antibody response, and repeated antigen presentation by B cells to T cells is necessary to induce B cell clonal expansion. Presentation of antigen by resting B cells to unprimed T cells tolerizes T cells, while anti-IgD antibody activates B cells and allows B cell antigen presentation that productively activates T cells. However, activation is not all that is required for B cells to productively present antigen to T cells.
