Melanization is a mechanism of innate immunity in arthropods wherein a thick
capsule of melanin is formed around foreign objects. Little is known about this pathway
biochemically though serine proteases are known to playa critical role. In this paper we began to address the roles of CLIPC3 and CLIPC1. Both are potential components of the
melanization pathway in A. gambiae. Knockouts are achived through injections of
dsRNA. After 4 days, sephadex beads were injected and after 24 hours, mosquitoes were
dissected and beads were scored for degree of melanization. Knockout of CLIPC1
showed little variation in the melanization levels observed compared with the control
GFP injections. CLIPC3 knockouts showed an increase in lack of melanization and a
decrease in complete melanized of bead comparison with the control. We conclude
CLIPC3 is involved in the melanization pathway of A. gambiae and it is unlikely CLIPC1.
