Explanation:
Detailed explanation-1: -MHC class II regulates B cell activation, proliferation, and differentiation during cognate B cell-T cell interaction. This is, in part, due to the MHC class II signaling in B cells.
Detailed explanation-2: -B lymphocytes originate in the bone marrow; their goal is to recognize an antigen. Each of them responds to the antigen in a specific way, as it expresses specific antibodies on the membrane (IgM, CD79a, and CD79b).
Detailed explanation-3: -There are three major types of MHC class II-restricted APCs: dendritic cells, B cells, and macrophages.
