Specialized white cells concerned in the body's immune system. Several different types can be distinguished. B lymphocytes produce antibodies (IMMUNOGLOBULINS) and are divided into the plasma cells that secrete the immunoglobulins and memory cells that act when the event that stimulated antibody selection recurs. T lymphocytes help to protect against virus infections and cancer and are divided into helper cells, suppressor cells, cytotoxic cells, memory cells and mediators of delayed hypersensitivity. There are also large granular lymphocytes. These are the KILLER CELLS (K cells) and the natural killer cells (NK cells).


Small white blood cells that bear the major responsibility for carrying out the activities of the immune system; they number about 1 trillion.


population of white blood cells (22–28% of circulating leukocytes)
  • B lymphocytes; B cell non-thymus-dependent, circulating or lymph gland-located lymphocyte, of short lifespan; produce immunoglobulins in response to presented antigens

  • T lymphocytes; T cell thymus-derived lymphocyte, of long lifespan (months/years) responsible for cell-mediated sensitivity

lymphocytes (limˑ·f·sāts), white blood cells of the agranulocyte type, originally from stem cells, that produce antibodies and attack harmful cells. There are two categories of lymphocytes: B cells and T cells.

Q. What is the best treatment for Acute Lymphocytic Leukemia? What is the best treatment for Acute Lymphocytic Leukemia? Can you please give me the hospital names and the location where the treatment could be done?
