Barrier in mosquito midgut protects invading pathogens

Scientists studying the Anopheles gambiae mosquito have found that the act of feeding triggers two enzymes to form a protective barrier that prevents the mosquito's immune defense system from clearing disease-causing agents that can be passed on to humans. Disrupting the protein barrier can trigger mosquito immune defenses to intervene and protect the insect from infection. This finding could inform new strategies for blocking malaria transmission.
