چکیده انگلیسی


• DC subsets play different roles at different time points of Leishmania infection.
• Cross-presenting DC subsets are required to confer protection by Th1 cells.
• A post-infection vaccine may be possible.

Mouse models of Leishmania major infection have shown that a predominant CD4+ T helper type 1 cell (Th1) response leads to protection, while T helper type 2 cell (Th2) predominance confers susceptibility. Dendritic cells (DCs) are antigen-presenting cells that orchestrate the T cell response. The immune response to L. major involves direct antigen presentation by migrating DCs or transfer of antigens to resident DCs to prime T cells. In this review, we discuss the timing and consequences of antigen presentation by DC subsets and how this affects Leishmania susceptibility. We propose a model where dermal DCs and Langerhans cells play a role early in infection, followed by inflammatory monocyte-derived DC and lymph node (LN)-resident DCs at later time points of infection to establish the resistant Th1 response.
