iNOS-Producing Inflammatory Dendritic Cells Constitute the Major Infected Cell Type during the Chronic Leishmania major Infection Phase of C57BL/6 Resistant Mice
Leishmania major parasites reside and multiply in late endosomal compartments of host phagocytic cells. Immune control of Leishmania growth absolutely requires expression of inducible Nitric Oxide Synthase (iNOS/NOS2) and subsequent production of NO. Here, we show that CD11b+ CD11c+ Ly-6C+ MHC-II+ cells are the main iNOS-producing cells in the footpad lesion and in the draining lymph node of Le...
متن کاملWestern Blot Analysis of Sera from Leishmania major-Infected BALB/c and C57BL/6 Mice
In Leishmania (L.) major-infected BALB/c mice Th2-type cells results in disease progression, whereas C57BL/6-infected mice mount a Th1-type response, which leads to control of the infection. Th2 response correlates with IgG1 whereas, Th1 response supports switching to IgG2a subclasses. Since IgG isotype-dominated response depends on different CD4 + T cell subsets, we studied the antigenic profi...
متن کاملRoute of Infection Affects Pathogenicity of Leishmania major in BALB/c Mice
Introduction: The term Leishmaniasis applies to a group of parasitic diseases caused by the genus Leishmania. Route of infection is one of the variables that have been reported to influence the immune responses as well as the disease outcome in experimental models of leishmaniasis. This research aims to study the effect of route of infection on the pathogenicity of Leishmania major in BALB/c mi...
متن کاملAntigen requirements for efficient priming of CD8+ T cells by Leishmania major-infected dendritic cells.
CD4(+) and CD8(+) T-cell responses have been shown to be critical for the development and maintenance of acquired resistance to infections with the protozoan parasite Leishmania major. Monitoring the development of immunodominant or clonally restricted T-cell subsets in response to infection has been difficult, however, due to the paucity of known epitopes. We have analyzed the potential of L. ...
متن کاملRole of imiquimod as adjuvant for vaccination against Leishmania major infection in BALB/c mice
Various adjuvants in combination with different antigens have been utilized as a vaccine candidate against leishmaniasis. However, the search for ideal adjuvants is still pursued due to the inefficiencies of current compounds. In the present study, the effect of imiquimod, as an adjuvant, is studied with soluble Leishmania antigens (SLA) in BALB/c mice. Four groups of mice were immunized with S...
