White blood cells


White blood cells (a.k.a. leukocytes) are cells which form a component of the blood. They are produced in the bone marrow and help to defend the body against infectious disease and foreign materials as part of the immune system.

White blood cells known as lymphocytes arise from by mitosis of stem cells in the bone marrow. Some lymphocytes migrate to the thymus and become T cells that circulate in the blood and are associated with the lymph nodes and spleen.

People with this disease are susceptible to infections because their white blood cells do not produce an enzyme needed by their immune systems. This disease has been treated in two different ways.

Chemokines are molecular signals released by cells of the immune system that stimulate white blood cells to move to inflamed tissues. They are metaphoric "cries for help." The chemokines bind to receptors located on the white blood cells.

Cellular immunity is based on the interaction of MHC proteins found on surfaces of circulating cells and T lymphocytes (white blood cells that pass through the thymus gland during maturation).

Cancer of the developing blood cells in the bone marrow. Leukemia leads to rampant overproduction of white blood cells (leukocytes); symptoms usually include anemia, fever, enlarged liver, spleen, and/or lymph nodes.
