| abstractText | IL-12 is a pivotal cytokine in the induction of IFN-gamma-mediated protective immune responses. We tested the effects of rIL-12 administration to Mycobacterium avium-infected mice and found a limited ability to induce protection against the infection; this ability varied according to the mycobacterial strain studied. IL-12 accelerated the expression and production of IFN-gamma in both immunocompetent and immunodeficient SCID or CD4-depleted mice. Evidence of NK cell activation was found as well as an enhancement of the ability to adoptively transfer resistance with T cell-enriched spleen cell populations and an increase in inflammatory cell recruitment in the liver. The protective ability of IL-12 was dependent upon the endogenous production of IFN-gamma as evaluated by the use of specific neutralizing Abs or IFN-gamma gene-disrupted mice. IL-12 potentiated the protective immunity conferred by a subunit vaccine containing M. avium culture filtrate proteins and dimethyl dioctadecyl ammonium chloride as an adjuvant. Thus, we show limited immunotherapeutic benefits from IL-12 administration in M. avium infections and promising results in its use as a coadjuvant in vaccine design. |
