Immunoprotective Leishmania major synthetic T cell epitopes
Using the predictive algorithm of Rothbard and Taylor (1988. EMBO J. 7:93) and the primary structure of gp63 (Button, L., and M.R. McMaster. 1988. J. Exp. Med. 167:724; Miller, R.A., S.G. Reed, and M. Parsons. 1990. Mol. Biochem. Parasitol. 39:267) we have been able to delineate the structures of a number of gp63 T-cell epitopes which stimulate the proliferation of CD4+ cells. One of these synt...
متن کاملInterleukin-10-mediated regulatory T-cell responses to epitopes on a human red blood cell autoantigen.
Regulatory T cells have been shown to control animal models of immune-mediated pathology by inhibitory cytokine production, but little is known about such cells in human disease. Here we characterize regulatory T-cell responses specific for a human red blood cell autoantigen in patients with warm-type autoimmune hemolytic anemia. Peripheral blood mononuclear cells from patients with autoimmune ...
متن کاملSafety and skin delayed-type hypersensitivity response in vervet monkeys immunized with Leishmania donovani sonicate antigen delivered with adjuvants.
In this study, we report on the safety and skin delayed-type hypersensitivity (DTH), responses of the Leishmania donovani whole cell sonicate antigen delivered in conjunction with alum-BCG (AlBCG), Montanide ISA 720 (MISA) or Monophosphoryl lipid A (MPLA) in groups of vervet monkeys. Following three intradermal injections of the inoculums on days 0, 28 and 42, safety and DTH responses were asse...
متن کاملPrediction of T-cell epitopes for designing a reverse vaccine against streptococcal bacteria
Streptococcal bacteria are among dangerous human pathogens with major prevalence worldwide. A good vaccine against streptococcal bacteria should have epitopes that confer protection from infection by different streptococcal bacteria types. we aimed was to recognize the most immunogenic and conserved epitopes of streptococcal bacteria, which could be a potential candidate for vaccine development...
متن کاملl-Arginine deprivation impairs Leishmania major-specific T-cell responses
The amino acid L-arginine plays a crucial role in the regulation of immune responses. We have recently shown that uncontrolled replication of Leishmania parasites at the site of pathology correlates with high levels of arginase activity in nonhealing leishmaniasis and that this elevated arginase activity causes local depletion of L-arginine. To further our understanding of the impact of L-argin...
