Enhanced accumulation of inflammatory neutrophils and macrophages mediated by transfer of T cells from mice immunized with Listeria monocytogenes.


We have previously shown that listeria-immunized mice recruit more inflammatory neutrophils and macrophages to the peritoneal cavity after i.p. injection of a sterile irritant than do nonimmune mice. Because the inflammatory phagocytes that were obtained from listeria-immune and nonimmune mice did not differ in their ability to kill Listeria monocytogenes in vitro, this suggested that the rapid recruitment of listericidal inflammatory neutrophils and macrophages may be critically important for resistance to listeriosis. In this study we demonstrate that the transfer of listeria-immune T cells, which enhances recipient resistance to listeriosis, also increases the ability of recipients to mobilize inflammatory neutrophils and macrophages to the peritoneal cavity after the i.p. injection of dead listeria. The transfer of enhanced inflammatory responsiveness was blocked by pretreatment of the transferred cells with anti-Thy-1.2 plus complement, and the magnitude of the inflammatory cell accumulation was dependent on the number of listeria-immune T cells that were injected. Inflammatory neutrophils and macrophages that were obtained from the mice after the transfer of listeria-immune or nonimmune T cells (plus dead listeria) did not differ in their ability to kill L. monocytogenes in vitro. These data suggest that the elicitation of an inflammatory response may be an important event in T cell-mediated resistance to listeriosis.
