Toxoplasma gondii infection induces metabolic alterations in the mouse cerebellum
Ontology highlight
ABSTRACT: Toxoplasma gondii is a protozoan parasite with a remarkable neurotropic affinity. We recently showed that T. gondii infection can alter the global metabolism of the cerebral cortex of the mice. However, the impact of this infection on the metabolism of the cerebellum remained unclear. In this study, we compared the metabolomic profiles of mouse cerebellum following acute and chronic infection with T. gondii. Three-week-old female BALB/c mice (n = 36) were commercially obtained from Lanzhou University Laboratory Animal Center (Lanzhou, China). Mice were separated into 6 groups (6 mice/group). The mice in the infected groups were challenged with 10 T. gondii cysts of PRU strain suspended in 0.5 ml phosphate-buffered saline (PBS), whereas the mice in the control groups were sham treated with 0.5 ml PBS only. All mice were provided non-medicated feed and water ad libitum during the experiment. The mice were monitored twice daily for signs of illness and mortality. At 7, 14, and 21 days post infection (dpi), mice from infected and control group were humanely sacrificed by CO2 asphyxiation and cerebellum of each mouse was dissected with scissors and forceps. Then, the metabolite profile changes in the cerebellum of mice following infection of T. gondii was analyzed.
