Macrophage
Some pathogens subvert this process and instead live inside the macrophage. Surrounding intestinal epithelial cells release TGF-β, which induces the change from proinflammatory macrophage to noninflammatory macrophage.

Cellular backpacks for macrophage immunotherapy | Science Advances - AAAS
CD80 is a costimulatory molecule used to trigger an adaptive immune response in the presence of an antigen-presenting cell ( 24 ). Macrophages displaying IFN-γ backpacks showed marked increases in iNOS, MHCII, and CD80 expression relative to unpolarized cells ( Fig. 3A ). Here, we make several important observations.

Macrophage (ecology)
The terms "macrophage" and "microphage" are used in ecology to describe heterotrophs that consume food in two different ways. The terms "macrophage" and "microphage" were originally used in this sense by Jordan and Hirsch (1927; cited in Yonge 1928).

Can a macrophage differentiate back into a monocyte? I know that monocytes differentiate into macrophages when they enter the tissues, but do macrophages stay in those same tissues for the remainder of their lifespan,...
usually once a monocyte travels around the bloodstream for 1-3 days, it then leaves the bloodstream and travel to a tissue where it will differentiate to a macrophage

Alveolar macrophage
An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of IL-4 has dual effects upon macrophage biological function, which may be either stimulatory or inhibitory.

Macrophage polarization
Although M2 activation state involves heterogeneous macrophage populations, some markers are shared between subtypes, thus the strict macrophage division This plasticity of macrophage phenotype has added to the confusion regarding the existence of individual macrophage sub-types in vivo.

Nov 20, 2022Objective: To explore the effect of macrophage-derived exosomes on the activation of hepatic stellate cells and its possible mechanism.Methods: Differential ultracentrifugation was used to extract macrophage exosomes. The exosomes were co-cultured with the mouse hepatic stellate cell line JS1, and a control group was established with phosphate buffered saline (PBS).
