Mammalian Hemopexin Protects Blood-Feeding Dipterans from Heme Toxicity and Promotes Parasite Transmission
This study reveals that mammalian hemopexin taken up by blood-feeding dipterans retains its heme-scavenging activity to protect vectors from heme toxicity and maintain gut homeostasis, thereby inadvertently promoting the development and transmission of parasites like *Plasmodium* and *Leishmania*.
