Structure, assembly and inhibition of the Toxoplasma gondii respiratory chain supercomplex - Nature Structural & Molecular Biology
Here the authors demonstrate that the assembly of mitochondrial respiratory supercomplex (III2–IV) from Toxoplasma gondii is critical for parasite fitness. They reveal the basis for cytochrome b inhib...

Cryptosporidium modifies intestinal microvilli through an exported virulence factor
Cryptosporidium is a common intestinal infection of vertebrates and a significant threat to public health. Within the epithelial layer of the intestine, the parasite invades and replicates. Infected cells are readily detected under the microscope by the presence of elongated microvilli, particularly around the vacuole where the parasite resides. Here, we identify a family of Cryptosporidium virulence factors that are exported into the host cell during infection and localise to the microvilli. We examine the trafficking and function of the most highly expressed family member, MVP1, which appears to control the elongation of microvilli through engagement of host EBP50 and CDC42. Remarkably, this mechanism closely mirrors that of an enteropathogenic Escherichia coli virulence factor, MAP, which is also known to drive host microvilli elongation during infection. This highlights a unique instance where eukaryotic and prokaryotic virulence factors have convergently evolved to modulate host actin structures through a similar mechanism. ### Competing Interest Statement The authors have declared no competing interest.

Iron-mediated post-transcriptional regulation in Toxoplasma gondii
Author summary Although iron is essential for most cells, excess can be toxic, so uptake and storage must be carefully controlled. The ability to respond to iron is particularly important for parasite...
