Polymorphonuclear leukocytes (PMN) were induced in the peritoneum of a Balb/c mouse by ip injection of Fusobacterium nucleatum (FN) (greater than 95% PMN). A subpopulation of PMN harvested bore Ia surface antigens and stimulated a mixed lymphocyte reaction (MLR) when cultured with C57B1/6J splenocytes. The reaction was blocked by a short prior incubation of PMN with anti-Ia antibody or PMN cell depletion by the same antibody plus complement. The Ia antigen-bearing PMN were capable of antigenic modulation since incubation of PMN for 24 h rendered the cells incapable of stimulating an MLR. The Ia antigen-bearing PMN produced a soluble material that enhanced the phytohemagglutinin (PHA) response of murine splenocytes and the active material was a product of live cells since the supernatants contained no detectable lactate dehydrogenase activity. The data suggest that murine PMN subpopulations, defined by surface Ia antigen, can modulate mitogenic responses by production of an enhancing factor(s).
