Reactive lymphocyte surrounded by red blood cells. Reactive lymphocytes or variant lymphocytes are cytotoxic (CD8+) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 Âµm in diameter with varying size and shape. The nucleus of a reactive lymphocyte can be round, elliptic, indented, cleft, or folded. The cytoplasm is often abundant and can be basophilic.
There are three main types of lymphocytes: B cells, T cells, and natural killer (NK) cells. Lymphocytes compose approximately 15 to 40% of the total white blood cells in the body. In a healthy adult a lymphocyte count of 1000 - 4800 cells per microliter of blood is considered the normal range.ymphocytopenia or lymphopenia are alternate terms for low lymphocyte counts. When the lymphocyte count is lowered, the body's ability to resist and fight off infections is severely compromised and its susceptibility to cancer is increased. In addition, low lymphocyte counts may also lead to damage to various organs.
