Relatively long-lived phagocytic cell of mammalian tissues, derived from blood monocyte. Macrophages from different sites have distinctly different properties. Main types are peritoneal and alveolar macrophages, tissue macrophages (histiocytes), Kuppfer cells of the liver, and osteoclasts. In response to foreign materials may become stimulated or activated. Macrophages play an important role in killing of some bacteria, protozoa, and tumour cells, release substances that stimulate other cells of the immune system, and are involved in antigen presentation. May further differentiate within chronic inflammatory lesions to epithelioid cells or may fuse to form foreign body giant cells or Langhans' giant cells.
A large phagocytic cell found in connective tissues, especially in areas of inflammation; includes wandering cells in the blood and lymph and histocytes in the reticuloendothelial system.
Macrophages (big eaters, from makros `large` + phagein `eat`; abbr. MΦ), are a type of white blood cell that engulf and digest cellular debris, foreign substances, microbes, and cancer cells in a process called phagocytosis. Macrophages were first discovered by Élie Metchnikoff, a Russian bacteriologist, in 1884. They are found in essentiall...Found on http://en.wikipedia.org/wiki/Macrophage

The terms `macrophage` and `microphage` are used in ecology to describe heterotrophs that consume food in two different ways. Both macrophages and microphages `ingest solid food and may process it through some sort of alimentary canal.` However, a macrophage `handles food items singly, while a microphage handles food items in bulk...Found on http://en.wikipedia.org/wiki/Macrophage_(ecology)
a large immune system cell in the tissues that devours invading pathogens and other intruders. Macrophages stimulate other immune cells by presenting them with small pieces of the invaders. Macrophages also can harbor large quantities of HIV without being killed, acting as reservoirs of the virus.Found on http://www.translationdirectory.com/glossaries/glossary031.htm

Macrophage: A type of white blood that ingests (takes in) foreign material. Macrophages are key players in the immune response to foreign invaders such as infectious microorganisms. Blood monocytes migrate into the tissues of the body and there differentiate (evolve) into macrophages. Macrophages help destroy bacteria, protozoa, and tumor cells.

Type of white blood cell, or leucocyte, found in all vertebrate animals. Macrophages specialize in the removal of bacteria and other micro-organisms, or of cell debris after injury.
