Abstract

Setting: Experimental murine tuberculosis. Objective: To evaluate the effect of cytokine modulation by thalidomide on the progression of the lung granulomatous response following aerosol tuberculosis infection in mice. Design: Mice infected by the respiratory route with 200-500 viable Mycobacterium tuberculosis Erdman were treated with daily subcutaneous injections of thalidomide (30 mg/kg) or saline for 4 weeks. The bacillary load, granulomatous response and cytokine production in the lungs were evaluated. Results: Aerosol M. tuberculosis infection resulted in a progressive granulomatous response in the lungs. At 28 days after infection, large granulomata with central necrosis and no apoptosis were observed. The infection induced high serum and lung cytokine mRNA levels. Thalidomide treatment resulted in a significant reduction in tumor necrosis factor-α, interleukin 6 (IL-6) and IL-10 protein levels (blood) and mRNA expression (lungs). IL-12 and interferon-γ were unaffected. The lungs of thalidomide-treated mice had smaller granulomata with apoptotic cells and no necrosis. Thalidomide treatment did not change the bacillary load. Conclusion: Thalidomide immunomodulation reduces inflammatory cytokines and concomitant lung pathology following acute aerosol M. tuberculosis infection, without increasing the bacillary load.
