LYMPHOCYTE -
Noun: One of the nearly colourless cells of the blood and lymphatic system, produced in part by the bone marrow but mostly in the lymph nodes and thymus gland . The number of lymphocytes are generally not affected in a patient with aplastic anaemia or myelodysplasia because they are bone marrow diseases. Lymphocytes have a nucleus and are chiefly responsible for immunity. They defend the body against infection by producing antibodies or toxic substances that destroy viruses and other foreign bodies. B cells and T cells are lymphocytes .

In patients who have AA or MDS , whether they have the immunosuppressive therapy or the bone marrow transplant, drugs such as ALG / ATG , Cyclosporine and Cyclophosphamide will be given to kill off the lymphocytes, particularly the T cells.

Here is a picture of 2 Lymphocytes in with some red blood cells and a few platelets.
