My laboratory is investigating proteins present in the hemolymph (blood) of insects, with special interest in the proteins' functions in the insect immune system. We are studying plasma proteins, including prophenoloxidase, serine proteases, protease inhibitors from the serpin superfamily, and lectins that bind to microbial polysaccharides. We also study proteins present in hemocytes, using monoclonal antibodies and biochemical and molecular biological approaches. The long range goal is to understand the biochemical and cellular processes by which insect immune systems recognize and respond to pathogens and parasites. We also investigate the biochemistry of cuticle protein cross linking, which is responsible for the unique physical properties of insect exoskeletons.
