Detailed explanation-1: -B cell structure and function During T cell-dependent activation, B cells absorb the antigen and then present pieces of the antigen on their surface via a major histocompatibility complex (MHC). Helper T cells can then recognize those antigens via the MHC and activate the B cells.
Detailed explanation-2: -Binds to MHC class II on antigen-presenting cells.-CD4 binds to constant regions on the MHC class II. The following is characteristic of B-but not T-cells: A Class I MHC.
Detailed explanation-3: -The antigen-recognition molecules of B cells are the immunoglobulins, or Ig. These proteins are produced by B cells in a vast range of antigen specificities, each B cell producing immunoglobulin of a single specificity (see Sections 1-8 to 1-10).
Detailed explanation-4: -Once the B cells bind to this protein, called an antigen, they release antibodies that stick to the antigen and prevent it from harming the body. Then, the B cells secrete cytokines to attract other immune cells. They also present the antigens to T cells, which they recognize using their T cell receptors (TCRs).
