A lymphocyte is a type of white blood cell in the immune system of jawed vertebrates. Lymphocytes include natural killer cells (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody-driven adaptive immunity).

B cells or B lymphocytes are part of the adaptive immune response. Once activated, these white blood cells produce antibodies. B lymphocytes have further roles as antigen-presenting cells and cytokine secretors. This cell type is classified into four main groups: transitional, naïve, plasma, and memory B cells.

Long primary RNA transcript with VDJ If your doctor determines that your lymphocyte count is high, the test result might be evidence of one of the following conditions: Infection (bacterial, viral, other) Cancer of the blood or lymphatic system; An autoimmune disorder causing ongoing (chronic) inflammation; Specific causes of lymphocytosis include: Acute lymphocytic leukemia There are three types of lymphocytes: B cells, T cells, and natural killer (NK) cells. These white blood cells make up about 20% to 40% of all white blood cells in the body, and the normal range for lymphocytes is a count of 1,000 to 4,800 cells per microliter of blood.

2010-12-23 · T lymphocytes and B lymphocytes are two types of lymphocytes present in our blood.

B and T lymphocytes later differentiate into effector and memory cells on exposure to antigens. Lymphocytes are responsible for both humoral (antibody-mediated) and the cell-mediated immune (CMI) response by B and T lymphocytes, respectively.
