SLC44A4 and infection: These authors’ observations (36, 37) could explain the similar Plasmodium-agonistic roles of AgCTL4 and AgCTLMA2 that have been observed by us and by others (12), as well as the differences in infection phenotype upon gene silencing between A. gambiae and A. albimanus, given that the divergence of AaCTL4 may in some way abolish or change the CTLMA2-CTL4 heterodimer.
