The peritrophic matrix (PM) is a chitin-containing acellular sheath that surrounds the blood meal and separates the food bolus from the midgut epithelium. Intense molecular traffic through the PM occurs during digestion. Digestive enzymes secreted by the midgut epithelium must traverse the PM to reach their substrates in the food bolus, and digestion products must cross the PM in the opposite direction to be absorbed by the epithelial cells. Here we report that the PM limits the rate of… CONTINUE READING
