We thank Sukanya Narasimhan and Kathleen DePonte for their assistance, helpful comments, and lab support. We thank the Johns Hopkins Malaria Research Institute insectary and parasitology core facilities for mosquito rearing and parasite infections. In addition, we would like to acknowledge the Mass Spectrometry (MS) & Proteomics Resource of the W.M. Keck Foundation Biotechnology Resource Laboratory at Yale University for their work supported by the NIH shared instrument grants ODOD018034 (Q-Exactive Plus) and RR031795 (LTQ-Orbitrap Elite). These studies were also supported by funding from the NIH T32 (AR007016-43) to M.F. and from the Howard Hughes Medical Institute to E.F.

N2 - The key step during the initiation of malaria is for motile Plasmodium parasites to exit the host dermis and infect the liver. During transmission, the parasites in the form of sporozoites, are injected together with mosquito saliva into the skin. However, the contribution of vector saliva to sporozoite activity during the establishment of the initial infection of the liver is poorly understood. Here we identify a vector protein by mass spectrometry, with similarity to the human gamma interferon inducible thiol reductase (GILT), that is associated with saliva sporozoites of infected Anopheles mosquitoes and has a negative impact on the speed and cell traversal activity of Plasmodium. This protein, referred to as mosquito GILT (mosGILT) represents an example of a protein found in mosquito saliva that may negatively influence sporozoite movement in the host and could lead to new approaches to prevent malaria.
