Abstract
When macrophages from lepromatous leprosy patients are exposed to M. leprae, the macrophages show reduced protein synthesis. Such a phenomenon is not seen with macrophages from tuberculoid patients or normal individuals. M. leprae phagocytized by Schwann cells affect the incorporation of DNA precursor in the cells, leading to failure of Schwann cell association with axons in in vitro cultures. These 2 observations form a basis of proposing that basic biochemical events take place when M. leprae are associated with host cells, which in turn can be amplified to physiologically functional defects.
