Toxoplasma gondiiis an intracellular parasite that does not differentiate among hosts and is capable of infecting nearly all warm-blooded vertebrates. Although about 30% of the human population is thought to be infected withT. gondii, it is one of the most common opportunistic infections that does not cause serious symptoms when the immune system is functioning normally. In this review, we focus on anti-T. gondiiinfection by host innate immunity, acquired immunity, and type II interferon-mediated cell-autonomous immunity.T. gondiihas three types of secretory structures, rhoptries, dense granules, and micronemes, among which molecules released fromT. gondiivia rhoptries and dense granules act to inhibit host responses to eliminate.T. gondii.The molecules released byT. gondiithrough rhoptries and dense granules not only act to suppress host immunity, but also to control gene expression in infected cells, thereby favouring the spread of infection.T. gondiihas survived to this day, and may continue to evolve by skilfully applying its own factors to the infected host.
