TLR4 and malaria: The activation of key anti‐microbial Anopheles signaling pathways is, to a significant degree, pathogen‐specific: the Toll pathway is typically triggered by Gram‐positive bacteria, fungi, and the rodent malaria parasite Plasmodium berghei, while the immune deficiency (Imd) pathway is triggered by both Gram‐positive and Gram‐negative bacteria and the human malaria parasite Plasmodium falciparum.
