Abstract Biological studies of the determinants of Cryptosporidium infectivity are lacking despite the fact that cryptosporidiosis is a major public health problem. Recently, the 60-kDa glycoprotein (GP60) has received attention because of its high s

ABSTRACTCryptosporidiosis is a major cause of severe diarrheal disease in infants from resource poor settings. The majority of infections are caused by the human-specific pathogen C. hominis and absence of in vitro growth platforms has limited our un

ABSTRACT In both mice and humans, Type II interferon gamma (IFNγ) is crucial for the regulation of Toxoplasma gondii (T. gondii) infection, during acute or chronic phases. To thwart this defense, T. gondii secretes protein effectors hindering the ho

ABSTRACT Toxoplasma gondii bradyzoites play a critical role in pathology due to their long-term persistence in intermediate hosts and their potential to reactivate, resulting in severe diseases in immunocompromised individuals. Currently, there is no

Abstract Cryptosporidium parvum is an obligate intracellular parasite with a highly reduced mitochondrion that lacks the tricarboxylic acid cycle and the ability to generate ATP, making the parasite reliant on glycolysis. Genetic ablation experiments

ABSTRACTAutophagy contributes to innate immunity by targeting intracellular pathogens for elimination. Previous studies identified a non-canonical autophagy pathway that controls Toxoplasma gondii infection in a strain-dependent manner in interferon

ABSTRACTGenes required for the lysosomal degradation pathway of autophagy play key roles in topologically distinct and physiologically important cellular processes. Some functions of ATG genes are independent of their role in degradative autophagy. O

Toxoplasma gondii acquires host cytosolic materials, yet the mechanism remains unknown. Wan et al. reveal the micropore as an essential organelle at the plasma membrane for endocytosis of host cytosolic proteins and biotin, and Golgi ceramide.

Autophagy is a highly conserved process that utilizes lysosomes to selectively degrade a variety of intracellular cargo, thus providing quality control over cellular components and maintaining cellular regulatory functions. Autophagy is triggered by

Protein phosphorylation and dephosphorylation are essential aspects of biology. Wang et al., report that Toxoplasma gondiiprotein phosphatase 2A (PP2A) mediated dephosphorylation is critical for starch metabolism and bradyzoite differentiation.
