Abstract

We studied the effects of administration of recombinant interleukin-1 alpha (rIL-1 alpha) to mice after immunization with killed Listeria monocytogenes cells on the promotion of the functional differentiation of T cells in vivo. Mice immunized with killed L. monocytogenes were unable to express cell-mediated immunity to specific antigen in vivo, as determined by delayed-type hypersensitivity (DTH) and acquired cellular resistance (ACR), and splenic T cells obtained from such mice were unable to respond to rIL-2 and specific antigen and to produce IL-2 after antigenic restimulation in vitro. When rIL-1 alpha was given to mice after immunization with killed bacteria. T cells became capable of responding to rIL-2 and specific antigen in vitro. These functions of T cells were similar to those from mice immunized with viable listeriae. Moreover, using a local passive transfer system, it was found that effector T cells mediating DTH but not ACR to L. monocytogenes were generated in mice treated with rIL-1 alpha after immunization with killed bacteria. These T cells were able to produce macrophage chemotactic factor but not macrophage-activating factor or gamma interferon in vitro in response to stimulation with specific antigen. These results suggest that in vivo administration of rIL-1 alpha facilitates the maturation of antigen-specific T cells mediating DTH and that different effector T cells mediating DTH or ACR are involved in cell-mediated immunity to L. monocytogenes.
