A novel vasodilatory peptide from the salivary glands of the sand fly Lutzomyia longipalpis

Science. 1989 Jan 13;243(4888):212-4. doi: 10.1126/science.2783496.

Abstract

Salivary gland lysates of the sand fly Lutzomyia longipalpis contain a potent vasodilator that aids the fly to feed on the blood of its vertebrate hosts. Chromatographic analysis, antibody reactivity, and data obtained from bioassays of the salivary erythema-inducing factor indicate striking similarity with human calcitonin gene-related peptide. The erythema-inducing factor is, however, at least one order of magnitude more potent than calcitonin gene-related peptide.
