Abstract

Plasmodium gametes and sporozoites activate surface-bound plasminogen to plasmin that degrades extracellular matrix barriers, therewith facilitating parasite motility in mosquitoes and mammalian hosts. To control malaria transmission, Pascini et al. generate Anopheles stephensi transgenic mosquitoes constitutively secreting human plasminogen activator inhibitor 1 in midgut and/or saliva which leads to inhibition of plasminogen activation and a reduction in oocyst intensity, infection prevalence, and transmission.
