Induction of Th1 Cytokines by Live Logarithmic Promastigotes of L. major
The early cytokines production in response to live logarithmic and stationary phase promastigotes of Leishmania major was examined on the peripheral blood cells of the healthy individuals. Whole blood cultures were stimulated by either logarithmic or stationary phase promastigotes. IFN- and IL-10 productions were assessed by specific sandwich ELISA. The results showed that the logarithmic prom...
متن کاملVaccination with Live Attenuated L. Major and TLR4 Agonist Promotes a Th1 Immune Response and Induces Protection against L. Major Infection in BALB/c Mice
Background: Toll like receptors play a major role in immune responses against Leishmania parasites. Objective: To evaluate the efficacy of vaccination with live attenuated L. major and TLR4 agonist in protection against L. major infection. Methods: Attenuated L. major was prepared by continuous sub-culturing of the parasite. A total of 90 mice were assigned to 9 groups including 6 groups of BAL...
متن کاملVaccinations with live-attenuated Leishmania major promastigotes and challenge infection with L. major in BALB/c mice.
BACKGROUND Currently there is no vaccine available in use against any form of leishmaniases worldwide. OBJECTIVE To assess potential of a live-attenuated Leishmania major promastigates, for protection against a challenge infection with L. major in BALB/c mice. DESIGN A laboratory based study. SETTING Study was carried out at Centre for Biotechnology Research and Development, Kenya Medical...

متن کاملHeat Shock Proteins Enriched-Promastigotes of Leishmania major Inducing Th2 Immune Response in BALB/c Mice
Background: Heat shock proteins (HSP) are highly conserved molecules with many immunological functions. They are highly immunogenic with important role in cancer immunotherapy and in vaccine development against infectious diseases. As adjuvant, HSP can augment the immunogenicity of weak antigens and can stimulate antigen presenting cells. Although vaccines have been successful for many infec...
