Defensive cells in the body that are capable of consuming foreign objects
"Big Eaters" work in conjunction with the dendritic cells as the immune system's first line of defense. Macrophages protect different organs (e.g. lungs, brain, liver).
A type of white blood cell that devours the invading microbe and then assists T cells in the production of antibodies against the same type of microbe.
Macrophages are phagocytes. After migration into the tissue, monocytes (white blood cells) become macrophages, which means "large eater."
Large tissue mononuclear cell having phagocytic and antigen-processing activity; develops from monocyte. Often act as hosts to intracellular pathogens. Upon activation, can kill pathogens (Lecture: Innate Immunity and Inflammation I, 2/19/02)
scavenger cells that keep the lung's air sacs clean.
enlarged monocytes (white blood cells) that engulf microbes and cellular debris.
Many forms of mononuclear phagocytes found in tissues. They perform many functions including killing of ingested microorganisms, digestion and presentation of antigens to T and B-lymphocytes and secretion of a large number of diverse products.
class of large-sized phagocytes, scavenger cells found in the bloodstream and many tissues; remove bacteria or other foreign bodies from the blood or tissues
the cells that accumulate glucosylceramide in Gaucher disease - they come from the bone marrow
a monocyte that exits the bloodstream to enter into body tissues
A large cell that ingests microorganisms or other cells and foreign particles. It also interacts with T- and B- lymphocytes to facilitate antibody production.
In response to foreign materials, these immune system cells may become stimulated and play an important role in killing some tumor cells, bacteria and protozoa.
A type of white blood cell that engulfs and destroys foreign materials.
white blood cells that can engulf antigens, immune complexes and release cytokines. They are activated by cytokines (innate) and immune complexes (acquired).
any of the large phagocytic cells of the reticuloendothelial system
A type of white blood cell derived from monocytes that engulf invading antigenic molecules, viruses, and microorganisms and then display fragments of the antigen to activate helper T cells; ultimately stimulating the production of antibodies against the antigen. PICTURE
cells – part of the immune system – which are present in most organs and tissues. They remove bacteria and other foreign bodies by ingesting them (a process known as phagocytosis)
large cells that ingest (engulf) microorganisms, foreign particles and other cells. Occur in the walls of blood vessels and in other connective tissue and are immobile, becoming actively mobile when stimulated by inflammation.
Cells of the immune system that destroy invading organisms or foreign proteins.
Cells in the blood that can engulf foreign proteins, bacteria, and other microorganisms. These cells are found in the spleen, lymph nodes, alveoli, and tonsils.
Large blood cells with many functions
a type of 'scavenger' cell, key to the workings of the human immune system. They are produced by stem cells in the bone marrow and circulate through the blood. They settle in many tissues, especially in the spleen and lymph nodes and in the liver, serving as filters to trap microbes and other foreign particles that arrive through the blood.
Macrophages are part of the innate immune system and their name comes from the Greek meaning “big eater”. These cells are responsible for the clean-up and elimination of pathogens, dead cells and cellular debris in the body.
Phagocytic cells derived from monocytes found in many different tissues
Scavenger white blood cells that remove dead tissues and debris.
Immune cells that patrol the body for nonspecific invaders, engulfing them for destruction or for presentation to specialized immune cells.
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Macrophages from different sites have distinctly different properties. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPPFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS. (from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Large immune cells responsible for destroying foreign bodies that enter the blood. They also stimulate other immune cells by presenting them with small pieces of these foreign bodies. In HIV, macrophages can become a harbor for large quantities of HIV without being killed, acting as a safe storage area for the virus.
Phagocytes of the tissue; together with the Monocytes they form a defence system against firm particles from outside the body.
