A white blood cell that phagocytizes necrotic cell debris and foreign material, including viruses, bacteria, and tattoo ink. It presents foreign antigens on MHC II to lymphocytes. Part of the innate immune system
A "white blood cell" or phagocytic cell that helps to protect the body against infections and harmful substances
A white blood cell that engulfs and digests foreign organisms Macrophages also stimulate helper T-cells to participate in the immune system response
{i} large white blood cell which destroys foreign and potential harmful particles (Biology)
A macrophage is a large scavenger cell present in connective tissue and many major organs and tissues including the bone marrow, spleen, lymph nodes, liver and the central nervous system Macrophages ingest bacteria and cell debris and are responsible for the breakdown of worn-out red blood cells
a large scavenger white blood cell that ingests and processes degenerated cells and foreign invaders The long-lived macrophages can harbor large quantities of HIV, and may act as viral reservoirs
type of white blood cell that resides in tissues, out of the bloodstream, where it attacks foreign substances and helps the rest of the immune system identify harmful toxins, bacteria, and viruses
A large scavenger cell that ingests degenerated cells and foreign organisms Macrophages exist in large numbers throughout the body and contribute to the development of acquired immunity by acting as antigen presenting cells They also ingest and destroy foreign matter coated with antibody Macrophages can be infected by HIV
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
a phagocytic tissue cell of the mononuclear phagocyte system that may be fixed or freely motile, is derived from a monocyte, and functions in the protection of the body against infection and noxious substances
a large (phagocytic) cell in the immune (reticuloendothelial) system This is the reconnaisance unit of the blood stream -- circulatin, looking for foreign matter, alerting (by producing neopterin) the entire immune system if there is a problem
The name for a large mononuclear phagocytic cell, present in blood, lymph, and other tissues Macrophages are derived from monocytes They phagocytose and destroy pathogens; some macrophages also activate B cells and T cells (See 705)
a type of white blood cell that assists the bodys fight against bacteria and infection by engulfing and destroying invading organisms
A type of tissue cells that is derived from the blood monocyte The monocyte migrates from the blood into tissues where it transforms into a macrophage Macrophages are present in most tissues The cell takes many forms and has several functions Three examples of macrophage functions are 1) ingest and degrade debris during tissue repair and remodeling, 2) ingest and kill or contain the growth of microorganisms, and 3) process and present antigens to lymphocytes
A large cell that helps the body defend itself against disease by surrounding and destroying foreign organisms (such as viruses or bacteria)
A phagocytic tissue cell of the reticuloendothelial system that may be fixed or freely motile, is derived from a monocyte, and functions in the protection of the body against infection and noxious substances
a type of white blood cell that assists in the body's fight against bacteria and infection by engulfing and destroying invading organisms
