[Interferon activation of the production of a factor increasing the bactericidal properties of mouse macrophages]

It has been established that the administration of homologous interferon to mice activates the production by splenocytes of a factor increasing the bactericidal properties of macrophages in the peritoneal exudate. The activation effect was dose-dependent. The maximum production was noted on day 3 after the injection of interferon, type I, or its inducers. Cell-producers of the factor are mainly lymphocytes.
