However, available clinical drugs for toxoplasmosis not only cause severe adverse effects but also demonstrate reduced therapeutic efficacy due to the emergence of drug-resistant strains, highlighting the urgent need for novel therapeutic interventions. This study aimed to evaluate the activity of dimethyl itaconate (DI) against\n                    <jats:italic>T. gondii<\/jats:italic>\n                    both\n                    <jats:italic>in vitro<\/jats:italic>\n                    and\n                    <jats:italic>in vivo<\/jats:italic>\n                    and to elucidate its underlying mechanism of action. The\n                    <jats:italic>in vitro<\/jats:italic>\n                    antiparasitic effects of DI were comprehensively investigated using transmission electron microscopy (TEM), plaque assays, quantitative PCR (qPCR), mitochondrial functional assays, ELISA, and transcriptomic profiling.\n                    <jats:italic>In vivo<\/jats:italic>\n                    evaluations were conducted in\n                    <jats:italic>T. gondii<\/jats:italic>\n                    -infected mouse models to assess survival rates, parasite loads, histopathological changes, and oxidative stress modulation. The results revealed that DI-treated tachyzoites exhibited marked organelle disruption, loss of membrane integrity, and activation of autophagy. Plaque assays combined with qPCR analysis consistently demonstrated a dose-dependent suppression of\n                    <jats:italic>T. gondii<\/jats:italic>\n                    proliferation. Notably, DI induced mitochondrial dysfunction, characterized by reduced mitochondrial membrane potential, ATP depletion, and a concomitant increase in reactive oxygen species (ROS) levels, consistent with the transcriptomic profiling data. This mechanistic evidence suggests that DI exerts its inhibitory effects on\n                    <jats:italic>T. gondii<\/jats:italic>\n                    tachyzoites primarily by disrupting the parasite\u2019s energy metabolism pathways.\n                    <jats:italic>In vivo<\/jats:italic>\n                    , DI administration increased survival rates, partially alleviated histopathological damage, significantly reduced parasite loads in target organs, and mitigated oxidative stress and inflammatory responses.
