Avaliação imunohistoquímica da atividade macrofágica e sua relação com o fenômeno de apoptose na hanseníase

Abstract

The present study had for objective to evaluate the correlation between the activity of macrophage and the apoptosis in the polar forms of the leprosy. For such constituted samples of 29 biopsies of patients' skin were analyzed with the polar forms of the leprosy. For the measure of the activity of macrophage and of the apoptosis, the method immunohistochemistry was used, seeking the markers lysozyme, CD68, iNOS (for activity of macrophage) and caspase 3 (for apoptosis). In the statistical treatment, it was used the test non parametric of Mann-Whitney and the lineal Correlation of Spearman. Do the obtained results suggest that the apoptosis rate suffers direct influence of the activity of macrophages in the lesions of patient TT, however in the lesions what was LL, noticed other factors they must it is inducing the programmed cellular death, possibly TGF-β.
