Histiocyte

Histiocytes are cells of the lymphocytic series that participate in the humoral and cellular defense of the body, synthesizing antibodies that are part of humoral immunity. Their macrophage function is phagocytosis and digestion of bacteria-infected cells. When cellular immunity is weakened, killer cells and their own lymphocytes can be replaced, which leads to disruption of their function and subsequent suppression of the immune system with the development of hypogammaglobulinemia. Bactericidal, antiprotease, antiendotoxic substances secreted by histiocytes inhibit the growth and reproduction of microorganisms. When bacteria and other foreign objects die, histiocytes release the so-called kinin-like factor and histamine, which, along with
