Using a lectin, Achatinin-H, having preferential specificity for glycoproteins with terminal 9-O-acetyl sialic acid derivatives linked in α2-6 linkages to subterminal N-acetylgalactosamine, eight distinct disease-associated 9-O-acetylated sialoglycoproteins was purified from erythrocytes of visceral leishmaniaisis (VL) patients (RBC(VL)). Analyses of(More)
We report the discovery and characterization of a glycosylated bacterial ABC-type phosphate transporter isolated from the peripheral blood mononuclear cell (PBMC) fraction of patients with visceral leishmaniasis (VL). Three disease-associated 9-O-acetylated sialoglycoproteins (9-O-AcSGPs) of 19, 56 and 65 kDa, respectively, had been identified and their(More)
Human leukocyte antigens (HLA) bind peptides generated by limited proteolysis in cells and present them at the cell surfaces for recognition by T cells. Through this antigen presentation function they control the specificity of T cell responses and thereby adaptive immune responses. Knowledge of HLA-bound peptides is thus key to understanding adaptive(More)
The aim of the study was to identify as potential therapeutic targets specific molecular alterations in tumor cells recognized by the immune system. To identify such targets, we analyzed the human leukocyte antigen (HLA) peptidomes of human melanoma cells by 2-dimensional nano-HPLC/mass spectrometry and tested the immunological significance of the peptides(More)
Dendritic cells (DCs) and macrophages are specialized APCs that process and present self-Ags for induction of tolerance and foreign Ags to initiate T cell-mediated immunity. Related to differentiation states they have specific phenotypes and functions. However, the impact of these differentiations on Ag processing and presentation remains poorly defined. To(More)
