Materno-foetal transmission causes one of the most serious forms of infection with the intracellular protozoan parasite Toxoplasma gondii. In the placenta, trophoblast cells constitute the barrier between maternal circulation and foetal tissue. We looked at the factors that determine the extent of cell adhesion to human BeWo trophoblast cells during T.(More)
The report presents two cases where diagnosis of alveolar echinococcosis was confirmed by Echinococcus multilocularis and Echinococcus granulosus PCR. The extrahepatic osseous involvement and the absence of initial hepatic involvement are unusual in both cases. Due to limitations of serological interpretation, PCR was useful to diagnose atypical(More)
Protective immunity in mice infected with Toxoplasma gondii is mainly mediated by NK cells, CD4 and CD8 T cells, and type 1 cytokines, such as gamma interferon (IFN-gamma). To clarify the roles of NK cells and IFN-gamma in protection against primary congenital toxoplasmosis, we used recombination activating gene 2 knockout (RAG-2(-/-)) mice, which lack T(More)
This study investigated the effect of infection with the apicomplexan parasite Toxoplasma gondii, in combination with the concomitant cytokine environment (IFN-gamma/TNF-alpha), on adhesion of THP-1 monocytic cells to MRC-5 fibroblasts. Surprisingly, infection of THP-1 cells decreased their adhesion to the MRC-5 cell monolayer. This decrease was compensated(More)
