Basic B cell function: bind an antigen, receive help from a cognate helper T cell, and differentiate into a plasma cell that secretes large amounts of antibody. B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype.They function in the humoral immunity component of the adaptive immune system by secreting antibodies.Additionally, B cells present antigen (they are also classified as professional antigen-presenting cells (APCs)) and secrete cytokines. cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype.
Though strictly speaking, an antibody is not the same as an immunoglobulin; B cells can produce two types of immunoglobulins-surface immunoglobulins, which are B cell receptors; and secreted immunoglobulins, which are antibodies. So antibodies are one of two classes of immunoglobulins.he ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region (located at the base of the Y), which contains a conserved glycosylation site involved in these interactions. The production of antibodies is the main function of the humoral immune system.
