ABSTRACT
Leishmania major is the main causal agent of cutaneous leishmaniasis (CL) that remains a serious public health concern in many tropical and subtropical countries. A long-lasting protective vaccine against leishmaniasis remains as a medical unmet need. Lipophosphoglycan 3 (LPG3) is one of the class II LPG genes from HSP90 family involved in the host immune responses. The aim of the present study is to investigate the capability of recombinant LPG3 (rLPG3) to induce Th1, Th2, Th17 responses. The results showed that rLPG3 in moderate and high concentrations significantly induced expression of Th1 lineage-specific transcription factor (T-bet) and cytokine (IFN-γ)(P < 0.05). Moreover, the Th1-stimulating effect of rLPG3 was confirmed by significant induction of IFN-γ secretion from treated T cells (P < 0.01). However, no significant effect of rLPG3 on Th2 and Th17 lineage cells was observed even in high concentration. Our findings demonstrate that rLPG3 induces Th1, but not Th2 and Th17, lineage responses. Further studies are needed to investigate adjuvant properties of rLPG3 for leishmania therapy.
