Depletion of Langerhans cells in the tongue from patients with advanced-stage acquired immune deficiency syndrome: relation to opportunistic infections
(WILEY-BLACKWELLMALDEN, 2012)
Aims: To quantify and compare the expression of Langerhans cells (LCs) in the tongue mucosa of AIDS patients with different opportunistic infections, and from acquired immune deficiency syndrome (AIDS) and non-AIDS patients ...
Regulation of T cell response to leishmania antigens by determinants of histocompatibility leukocyte class I and II molecules
(Brazilian Journal of Medical and Biological Research, 1998)
It has been shown that HLA class I molecules play a significant role in the regulation of the proliferation of T cells activated by mitogens and antigens. We evaluated the ability of mAb to a framework determinant of HLA ...

Comparison between ELISA using total antigen and immunochromatography with antigen rK39 in the diagnosis of canine visceral leishmaniasis
(Elsevier B.V., 2010-10-29)
In this study, an enzyme-linked immunosorbent assay using crude total antigen (CTA-ELISA) and immunochromatography with antigen rK39 were compared in the diagnosis of canine visceral leishmaniasis (CVL). Fifty-two total ...
Idiopathic focal segmental glomerulosclerosis and HLA antigens
(Associação Brasileira de Divulgação Científica, 1998-03-01)
The objective of the present study was to investigate a possible association between HLA class II antigens and idiopathic focal segmental glomerulosclerosis (FSGS). HLA-A, -B, -DR and -DQ antigens were determined in 19 ...
