Earlier our proteomic study revealed a novel protein, cofactor-independent phoshoglycerate mutase (LdiPGAM), an important enzyme in glucose metabolism, in T helper cells type 1 (Th1) stimulatory region of soluble<jats:italic>Leishmania donovani<\/jats:italic>antigen. In this study, LdiPGAM was biochemically and molecularly characterized and evaluated for its immunogenicity and prophylactic efficacy against<jats:italic>L. donovani<\/jats:italic>. Immunogenicity of recombinant LdiPGAM (rLdiPGAM) was initially assessed in na\u00efve hamsters immunized with it by analysing mRNA expression of inducible nitric oxide (NO) synthase (iNOS) and other Th1\/T helper cells type 2 cytokines, which revealed an upregulation of Th1 cytokines along with iNOS. Immunogenicity of rLdiPGAM was further evaluated in lymphocytes of treated<jats:italic>Leishmania<\/jats:italic>-infected hamsters and peripheral blood mononuclear cells of<jats:italic>Leishmania<\/jats:italic>patients in clinical remission by various parameters, viz. lymphoproliferation assay and NO production (hamsters and patients) and levels of various cytokines (patients). rLdiPGAM induced remarkable Lymphoproliferative response and NO production in treated<jats:italic>Leishmania<\/jats:italic>-infected hamsters as well as in patients and increase in interferon gamma (IFN-\u03b3), interleukin-12 (IL-12p40) responses in<jats:italic>Leishmania<\/jats:italic>patients in clinical remission. Vaccination with rLdiPGAM exerted considerable prophylactic efficacy (73%) supported by increase in mRNA expression of iNOS, IFN-\u03b3 and IL-12p40 with decrease in transforming growth factor beta and interleukin-10. Above results indicate the importance of rLdiPGAM protein as a potential vaccine candidate against visceral leishmaniasis.<\/jats:p>","DOI":"10.1017\/s0031182017001160","type":"journal-article","created":{"date-parts":[[2017,7,10]],"date-time":"2017-07-10T09:24:05Z","timestamp":1499678645000},"page":"508-526","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":7,"title":["Molecular,
