[The morphofunctional heterogeneity between peritoneal and alveolar macrophages in their biogenic amine content: the effect of their presence or absence in the microenvironment of mast cells].

Peritoneal macrophages differ from alveolar ones in biogenic amine content: peritoneal macrophages contain smaller amounts of histamine and serotonin. When activated, alveolar macrophages release biogenic amines, whereas in peritoneal macrophages stimulators of macrophage activity induce the increase in amine content. This may be due to the presence of mast cells in their microenvironment macrophage activity.
