  • Title: Salivary gland proteins of the mosquito Culex quinquefasciatus.
    Author: Nascimento EP, dos Santos Malafronte R, Marinotti O.
    Journal: Arch Insect Biochem Physiol; 2000 Jan; 43(1):9-15. PubMed ID: 10613958.
    Abstract:
    Several properties of the salivary glands of Culex quinquefasciatus mosquitoes were analysed. The amount of protein in female salivary glands increased from 0.26 microg on day one after emergence to about 1.4 microg on day seven. The major polypeptides found in the female salivary glands had molecular weights of 35.7, 28.3, and 20.5 kDa. Antibodies produced by mice immunized by bites of Culex quinquefasciatus female mosquitoes reacted with the 35.7 and 28.3 kDa polypeptides, showing that these molecules were secreted by mosquitoes during blood feeding. The salivary glands of C. Quinquefasciatus females displayed the same morphological and biochemical organization as that of Aedes aegypti mosquitoes, accumulating apyrase in the distal portions and alpha-glucosidase in the proximal portions of the gland.
