Imunoreatividade para tgf- β e caspase-3 e sua relação com o controle da resposta imune tecidual nas formas polares da hanseníase

Abstract

Leprosy is a chronic infect-contagious disease that accompanies the humanity for many years. Brazil occupies the second place in numbers of cases, and the state of Para is that presents the largest number of absolute cases. This study had as objective to evaluate the immunorreactivity for TGF-β and caspase-3 in the lepromatous and tuberculoid clinical forms of the leprosy evil trying to correlate the immunomarking pattern with the tissue control of the immune response of the host to the bacillus, through a retrospective study of paraffin enclosed tissue of 30 patients, being fifteen presenting in the lepromatous form and fifteen with the tuberculoid type of disease. The patients followed the protocol of leprosy diagnosis according to criteria of Health Ministry of Brazil and histopathologic features. It was observed that the lepromatous form of the leprosy presented a significant statistically correlation (p=0,4630) among TGF-β to caspase-3, evidencing that as the cytokine as the imunomarking of the apoptosis increase inch by inch and simultaneously in this polar form and that indirectly appear to a role of TGF-β in the control of the immunologic response in its place to the infection for the Mycobacterium leprae.
