E. Chyczewska et al., STIMULATION OF ALVEOLAR MACROPHAGES BY BCG VACCINE ENHANCES THE PROCESS OF LUNG FIBROSIS INDUCED BY BLEOMYCIN, Folia histochemica et cytobiologica, 31(3), 1993, pp. 113-116
It was found that the BCG vaccine injected subcutaneously to the rats
enhances the process of lung fibrosis induced by bleomycin. Pretreatme
nt of rats with this vaccine results in accumulation of activated macr
ophages in lung interstitium and in the bronchoalveolar spaces. It may
be suggested that the activated macrophages release various cytokines
which may stimulate the proliferation of fibroblasts and biosynthesis
of extracellular matrix components.
