| The current study investigated the impact of the CCR5, TLR2 and TLR11 on production of nitric oxide (NO), IL-6 and IL-12 and growth of T. gondii, high virulent RH strain and avirulent PLK strain. All examined knockout macrophages infected with PLK strain produced significant lower levels of IL-12. On the other hand, TLR2 and TLR11 macrophages infected with RH strain produced significantly reduced levels of IL-12 as compared to wild-type macrophages. TLR2 and TLR11 macrophages infected with PLK strain significantly inhibited the production of IL-6 when compared to wild-type macrophages. Interestingly, significant reduction in the IL-6 and NO production was observed in TLR2 macrophages infected with PLK strain as compared to wild-type macrophages or to the... |

| Oligomannose-coated liposome (OML)-based vaccines have been reported to induce Th1-based immunity against entrapped antigens in immunized animals and to show protective effects against several protozoal diseases. In the present study, we produced a recombinant Babesia rodhaini ribosomal phosphoprotein P0 (rBrP0) that showed immunological cross reactivity with another rodent Babesia parasite, B. microti. We evaluated the efficacy of vaccination with OML-entrapped rBrP0 on B. rodhaini and B. microti infections in mice. Prior immunization with the OML-based rBrP0 vaccine, or with a Freund’s adjuvant-based rBrP0 vaccine, failed to demonstrate any protective effect against lethal infection with B. rodhaini, but the OML-based vaccine did induce protective... |
