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.
B cell: A type of white blood cell and, specifically, a type of lymphocyte. Many B cells mature into what are called plasma cells that produce antibodies (proteins) necessary to fight off infections while other B cells mature into memory B cells. All of the plasma cells descended from a single B cell produce the same antibody which is directed against the antigen that stimulated it to mature. The same principle holds with memory B cells. Thus, all of the plasma cells and memory cells remember the stimulus that led to their formation.
