Resumo: |
Toxoplasma gondii is an obligate intracellular protozoan parasite that invades a wide range of host cells. Upon encountering host cells, the parasite releases a large variety of proteins from secretory organelles, such as micronemes, rhoptries and dense granules. The secretion of microneme protein is essential for parasite invasion. We found that a secreted protein with an altered thrombospondin repeat of Toxoplasma gondii (TgSPATR) was a novel microneme protein, which was different from known microneme proteins that carry thrombospondin repeat domains. TgSPATR was secreted in response to an intra-parasitic elevation of Ca2+ and probably secreted during early stages of parasite invasion. Thus, we suggested that TgSPATR, new member of microneme secretory protein, had a possible function in the invasion.
