CD8A and focal segmental glomerulosclerosis: CD4+ T and CD8+ T cells and cells stained for Leishmania antigen were quantified in part of samples showing different patterns of glomerulonephritis: focal segmental glomerulosclerosis (N = 8), mesangial proliferative glomerulonephritis (N = 8), membranoproliferative glomerulonephritis (N = 8), and minor glomerular abnormalities (N = 8).
