These Streptococci Kill White Blood Cells
Although a neutrophil can kill this bead-like string of Streptococcus pyogenes, this particular strain of bacteria expresses streptolysin-s on its surface which kills the white cell through necrosis, ...
White blood cells or leukocytes are cells of the immune system defending the body against both infectious disease and foreign materials.
White Blood Cells (leukocytes)
White blood cells
are much less numerous than red (the ratio between the two is around 1:700),

participate in protecting the body from infection, ...

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.
White blood cells, also known as leukocytes, are larger than erythrocytes, have a nucleus, and lack hemoglobin. They function in the cellular immune response. White blood cells (leukocytes) are less than 1% of the blood's volume.
Total white blood cells - All the white cell types are given as a percentage and as an absolute number per litre.
A complete blood count with differential will also include: ...
eosinophil White blood cells characterized by the presence of cytoplasmic granules that become stained by an acid dye.
eosinophilia Elevated eosinophil count in the circulating blood; commonly associated with chronic parasite infections.
A variety of white blood cells present in blood, lymph nodes, spleen, thymus gland, gut wall and bone marrow.

Neutrophils and macrophages are phagocytic white blood cells. This migration of white blood cells causes the redness and inflammation associated with infection.
Leukemia results from malignant white blood cells.
Lymphoma is a cancer of the lymphatic system cells that derive from bone marrow.
Myelomas are cancers of specialized white blood cells that make antibodies.

The primary hosts for HIV are the white blood cells variously called helper T lymphocytes, helper T cells, or CD4+ T cells.
The immune system contains white blood cells called T and B cells which make and secrete antibodies (proteins) to fight foreign molecules (including allergens), cells, and viruses. These foreign molecules, etc., are referred to as antigens.
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.
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).
These chemicals attract tissue macrophages and white blood cells to localise in an area to engulf (phagocytize) and destroy foreign substances.
A type of prostaglandin produced by various white blood cells involved in the inflammatory and immune responses and in allergic reactions.

Cancer of the developing blood cells in the bone marrow. Leukemia leads to rampant overproduction of white blood cells (leukocytes); symptoms usually include anaemia, fever, enlarged liver, spleen, and/or lymph nodes. [Talking Glossary]
Lysosome ...
Small bean-shaped structures scattered along the vessels of the lymphatic system. The lymph nodes produce white blood cells and filter bacteria and cancer cells that may travel through the system.

The calcified bones of your skeleton also work with the circulatory system. Marrow inside of your bones helps produce the cells inside of you blood. Both red blood cells and white blood cells are created in your bones.
