Host CD81 and Scavenger Receptor BI operate independently to mediate invasion of hepatocytes by different species of Plasmodium sporozoites, which use the parasite protein P36 as a key determinant of the entry route.
Plasmodium parasite transcription shifts dramatically along asexual development, and transmission stages variably express important immune evasion genes, suggesting much interesting biology has until now been hidden by bulk analyses.
The engagement of DNA crossings is shown to license ATP hydrolysis and DNA cleavage by topoisomerase VI, a finding with mechanistic ramifications for related GHKL ATPases and meiotic recombination machineries.
Cryo-EM structures of the ClpXP protease reveal how protein substrates are bound, show how spiral ClpX hexamers bind symmetry-mismatched heptameric ClpP rings, and suggest mechanisms for processive substrate translocation.
A comprehensive structural analysis of inhibitory murine antibody 3D11 binding to Plasmodium berghei circumsporozoite protein reveals common mechanisms of antibody evolution in mammals against Plasmodium parasites.
