Cellular immune responses to mycobacterial heat shock proteins in Nepali leprosy patients and controls. 1992

Mycobacterial Research Laboratory, Anandaban Leprosy Hospital, Kathmandu, Nepal.

Sixty-three leprosy patients, representing the entire leprosy spectrum from tuberculoid to lepromatous disease, and 17 healthy Nepali subjects were tested for their T-cell responses to the purified p65 and p70 protein antigens of Mycobacterium bovis BCG using a lymphocyte proliferative assay. There was strong correlation between the responses to BCG and M. leprae and the responses to the two antigens. Patients and controls lacking a response to either of the whole cell preparations failed to respond to the purified antigens, while BCG responders at the lepromatous pole of the disease did mount a response to both antigens. Significant differences in the magnitude of the responses to these antigens were obtained between controls and the disease groups. In individual subjects, responses to the two antigens were significantly correlated to each other.

D007918 Leprosy A chronic granulomatous infection caused by MYCOBACTERIUM LEPRAE. The granulomatous lesions are manifested in the skin, the mucous membranes, and the peripheral nerves. Two polar or principal types are lepromatous and tuberculoid. Hansen's Disease,Hansen Disease
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.
