In order to defend our body, macrophages release chemicals that are toxic to eliminate diseases and harmful foreign bodies. They also secrete growth factors that are essential in healing wounds.
B Cells
White blood cells, specifically neutrophils and macrophages, are responsible for surrounding and destroying bacteria in the body. Neutrophils can engulf bacteria through a process called phagocytosis, while macrophages can also secrete toxic chemicals to kill bacteria.
Macrophages do not replicate. The bone marrow produces Monocytes which when they find a damaged area transform into Macrophages.
The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.
There's a lot we don't currently know about lymphoid (ED3) Macrophages but it's relatively safe to assume that they do not have any major role in secreting antibodies. Macrophages tend to engulf and enzymatically destroy foreign objects in the body, this is their major purpose, if that object is coated in antibodies they're better at destroying it but they do not produce those antibodies themselves. The only real way that macrophages affect antibody production is that after destruction of intruder they'll present elements of the intruder to another variety of immune cell which will then go on to produce antibodies, it's also possible that they will produce interleukins or other compounds to upregulate antibody production but again: macrophages are not known to produce antibodies.
No, macrophages are responsible for removing dying or dead cells in the early stages of inflammation. Macrophages essentially ingest these.
They become larger and turn into macrophages
Alveolar macrophages, aka DUST CELLS.
Murine means "of, related to, or affecting rodents of the family Muridae," like mice. Murine macrophages are simply macrophages of these types of animals.
MACROPHAGES (Some Monocytes enter tissue, enlarge, and Mature into Macrophages).
