摘要

The mosquito Aedes aegypti transmits blood-borne viral pathogens that cause worldwide scourges such as dengue fever and West Nile virus. The mosquito's role in disease transmission is closely tied to its blood meals, which support the production of eggs—a process controlled by nutritional and hormonal pathways in the insect's digestive tract. Bart Bryant et al. (pp. 22391-22398) have uncovered a key regulator of mosquito physiology that controls both blood digestion and egg maturation. Levels of the regulator, a microRNA dubbed miR-275, rise 12 h after the mosquito feeds on blood, suggesting that nutritional and hormonal signals triggered by blood feeding might prompt production of the microRNA.
