Fluorescent tagging of Plasmodium circumsporozoite protein allows imaging of sporozoite formation but blocks egress from oocysts

M Singer, F Frischknecht - Cellular microbiology, 2021 - Wiley Online Library

Plasmodium oocysts: overlooked targets of mosquito immunity

RC Smith, C Barillas-Mury - Trends in parasitology, 2016 - cell.com
Although the ability of mosquitoes to limit Plasmodium infection is well documented, many
questions remain as to how malaria parasites are recognized and killed by the mosquito …

The malaria circumsporozoite protein has two functional domains, each with distinct roles as sporozoites journey from mosquito to mammalian host

A Coppi, R Natarajan, G Pradel, BL Bennett… - Journal of Experimental …, 2011 - rupress.org
