Evolved cytidine and adenine base editors with high precision and minimized off-target activity by a continuous directed evolution system in mammalian cells.

Continuous directed evolution of base editors (BEs) has been successful in bacteria cells, but not yet in mammalian cells. Here, we report the development of a Continuous Directed Evolution system in Mammalian cells (CDEM). CDEM enables the BE evolution in a full-length manner with Cas9 nickase.

Global profiling of protein S-palmitoylation in the second-generation merozoites of Eimeria tenella.

The intracellular protozoan Eimeria tenella is responsible for avian coccidiosis which is characterized by host intestinal damage. During developmental cycle, E. tenella undergoes versatile transitional stages such as oocyst, sporozoites, merozoites, and gametocytes.

Cloning, expression, and functional identification of aquaporin genes from Eimeria tenella.

Avian coccidiosis, caused by Eimeria spp., is one of the major parasitic diseases in chicken. Aquaporins (AQP) are essential mediators of water regulation and nutritional intake in parasites, and it may be a suitable molecule for chemotherapeutic target and vaccine candidate.

CRISPR-Cas9-based method for isolating microgametes of Eimeria tenella.

Eimeria tenella infections are known to cause severe caecal damage and death of the infected chicken. Gamogony is an essential stage in E. tenella life cycle and in the establishment of coccidiosis.
