Abstract

LP-BM5 murine leukemia virus (MuLV) injection causes murine AIDS (MAIDS), a disease characterized by many functional abnormalities of immunocompetent cells. We show that MAIDS mice are susceptible to Mycobacterium bovis Bacille Calmette-Guérin (BCG) infection as assessed by survival rate and bacterial counts. The peritoneal exudate macrophages from MAIDS mice produced a significant level of interleukin (IL)-12 soon after inoculation with BCG, whereas IL-15 and tumor necrosis factor (TNF) production were severely impaired in BCG-infected MAIDS mice. The appearance of natural killer (NK) and CD4⁺ T helper type 1 (Th1) cells specific for mycobacterial antigen were depressed in MAIDS mice after BCG infection. Thus, it appeared that impaired production of IL-15, besides other inflammatory cytokines, in MAIDS mice may be involved in the poor responses of the NK and Th1 cells, resulting in an increased susceptibility to BCG.
