https://www.selleckchem.com/products/Nobiletin(Hexamethoxyflavone).html Toxoplasma gondii, an obligate intracellular protozoan parasite, can establish a chronic infection in the brain by forming tissue cysts. This chronic infection is widespread in humans worldwide including developed countries, with up to one third of the population being estimated to be infected with this parasite. Diagnosis of this chronic infection is usually conducted by serological detection of IgG antibodies against this parasite. Since infected individuals remain positive for these antibodies for years, it has generally been considered that this infection is a lifelong infection. It is also often considered that this chronic infection is "latent" or "quiescent". However, recent discovery of the capability of perforin-dependent, CD8+ T cell-mediated immune responses to eliminate T. gondii cysts in collaboration with phagocytes illustrated dynamic interplays between T. gondii cysts and host immune system during this chronic infection. Importantly, the cytotoxic T cell-mediated protective immunity is able to remove mature cysts of the parasite. It is now clear that chronic T. gondii infection is not "latent" or "quiescent". Elucidating the mechanisms of the dynamic host-pathogen interactions between the anti-cyst protective immunity and T. gondii cysts and identifying the pathway to appropriately activate anti-cyst CD8+ cytotoxic T cells would be able to open a door for eradicating T. gondii cysts and curing chronic infection with this parasite.Ruminococcus gnavus is a Gram-positive anaerobe and normal gut commensal in the human host. There have been a small number of reported cases of infections attributed to R. gnavus, and no cases of urogenital infections have previously been published. We describe here a case of bilateral tubo-ovarian abscesses (TOAs) which cultured a pure growth of R. gnavus in a young female with concurrent deep infiltrating endometriosis and evidence of pelvic inflammato
