Mosquito saliva is a vehicle for the transmission of vector borne pathogens such asPlasmodiumparasites and different arboviruses. Despite the key role of the salivary glands in the process of disease transmission, knowledge of host-pathogen interactions taking place within this organ is very limited. To improve the experimental tractability of the salivary glands, we have generated fluorescent reporter lines in the African malaria mosquitoAnopheles coluzziiusing the salivary gland-specific promoters of theanopheline antiplatelet protein(AAPP), thetriple functional domain protein(TRIO) andsaglin(SAG) coding genes. Promoter activity was specifically observed in the distal-lateral lobes or in the median lobe of the salivary glands. Besides a comparison of the expression patterns of the selected promoters, the fluorescent probes allowed us to evaluate the inducibility of the selected promoters upon blood feeding and to measure intracellular redox changes. We also combined theaapp-DsRedfluorescent reporter line with a pigmentation-deficientyellow(-)mosquito mutant to assess the feasibility ofin vivomicroscopy of parasitized salivary glands. This combination allowed locating the salivary gland through the cuticle and imaging of individual sporozoitesin vivo, which facilitates live imaging studies of salivary gland colonization byPlasmodiumsporozoites.
