Lymphocytes are central to specific defenses and classified into two types, B lymphocytes (B cells) and T lymphocytes (T cells). Both lymphocytes play important roles in the body’s immune system.

Characteristics of B Cells

  • Maturation and differentiation of B cells will occur in the bone marrow itself.
  • Most B cells form plasma cells. Some B cells also become memory cells.
  • B cells are responsible for antibody-mediated immunity. B cells give rise to plasma cells that produce antibodies (specialized proteins that defend against microorganisms and help destroy substances, such as bacteria and viruses.)
  • B cells cannot be activated without the help of T cell (against most substances).
  • B cells = Plasma cells, Memory B cells and Immunoglobulins
