Project description
Dissecting the mechanism of foetal abortion in toxoplasmosis
Toxoplasmosis is an infection caused by the Toxoplasma gondii parasite. Despite it being a health hazard for both humans and livestock, the mechanism of vertical transmission from mother to foetus remains elusive. The EU-funded TOXOSHEEP project proposes to use a sheep animal model and investigate how the parasite reaches the placenta and induces inflammation that eventually causes foetal abortion. Insight into gene expression changes at the mother–foetus interface will help unveil important information on the T. gondii infection mechanism. Project findings will pave the way for the design of vaccines or drugs that block parasite transmission and improve the health of pregnant women and their foetuses.
Objective
Toxoplasma gondii is a major cause of abortion in humans and livestock, thereby producing a significant public health hazard and economic losses. Most of Toxoplasma’s virulence factors have been explored using mouse models; however, the murine immune response differs significantly from that of humans and farm animals. Despite Toxoplasma’s enormous economic and health implications, little is known about the factors that cause foetal mortality and vertical transmission in humans or livestock. The goal of this ambitious project is to close this gap in knowledge by studying the mechanisms involved in the early abortion during the acute phase of toxoplasmosis in a standardised animal model relevant for humans and livestock. We hypothesise that by using a pregnant sheep model, the molecular mechanisms underlying the parasite-induced inflammation associated with early abortions can be identified. To this end, we will first characterize the early infection dynamics, lesions, parasite burden and peripheral immune response in the dams. This will provide valuable information as to the initial immune response elicited by the parasite and how it reaches the placenta. Subsequently, we will investigate the local molecular mechanisms involved in the parasite-induced pathogenesis of early abortions by combining novel immunohistopathological and transcriptomic approaches in order to identify alterations of gene expression and biological pathways in the materno-foetal interface. The results derived from this proposal will significantly advance the understanding of the mechanisms of Toxoplasma early abortions and help in the design of transmission-blocking vaccines or drugs. Because Toxoplasma has been associated with women who had spontaneous abortions, it is likely that these mechanisms are shared with humans. Thus, these results will not only produce economic savings in the livestock industry but will also directly improve human health.
