[The dependence of the functional activity of "immune" macrophages on T-cells].

The dependence of the functional activity of the peritoneal macrophages of mice immunized with Francisella tularensis vaccine strain on the presence of T-cells in the culture has been studied. The elimination of "immune" macrophages and sensitized T-lymphocytes by means of anti-Thy-1-2-serum has been shown to lead to a sharp decrease in both ingestive and digestive functions of the phagocytic mononuclears of peritoneal exudate to the level of the activity of macrophages isolated from intact animals.
