Schematic view of the wounding and inflammation process in mosquito tissues during Plasmodium infection. Ookinetes wound the peritrophic matrix and midgut epithelial cells, which leads to the loss of some of these cells. Damaged epithelial cells are extruded, followed by the differentiation of regenerative cells and the consequent proliferative regeneration. The dead cells release intracellular contents that may function as DAMPs. ROIs and adenosine-containing molecules appear to be essential endogenous signaling molecules needed for protection against danger. In Anopheles spp., genes involved in biological processes such as immune recognition, immune signaling pathways, and autophagy are expressed during a Plasmodium infection. This expression can be detected locally in the gut and systemically in body fat. ROIs limit parasite development and have signaling activity in various tissues during infection. The ookinete differentiates into an oocyst in the space between the BM and the basal side of the epithelium. In this stage the parasite is susceptible to being melanized and is exposed to TEPs, AMPs, PO cascade products, and ROIs. Sporozoites emerge in the hemolymph, and are to some extent limited by the differentiation and proliferation of hemocytes. However, hemocytes have another perhaps more important function during the stage of sporozoites, which is the ability to sense small-sized BM fragments and adhere to sites where the BM is damaged and to places with cell debris. Basal lamina components for wound repair are produced by circulating hemocytes. Migration of sporozoites through the hemolymph and the tubular heart is probably hindered by the accumulation of hemocytes in the ostia. Finally, sporozoites accumulate in the salivary gland of the mosquito, from where they are transmitted to a vertebrate host.
