Updated project metadata. Toxoplasma gondii (T. gondii) is an opportunistic parasite that can infect the central nervous system, causing severe toxoplasmosis and behavioral cognitive impairment. Mortality is high in immunocompromised individuals with toxoplasmosis, most commonly due to reactivation of infection in the central nervous system (CNS). There are still no effective vaccines and drugs for the prevention and treatment of toxoplasmosis. There are five developmental stages for T. gondii to complete life cycle, of which the tachyzoite and bradyzoite stages are the key to the acute and chronic infection. In this study, to better understanding of how T. gondii interacts with the host central nervous system at different stages of infection, we constructed acute and chronic infection models of T. gondii in astrocytes, and used lab-free proteomics to detect the proteome changes before and after infection, respectively.
