Abstract
The focal point of my current research is increasing the understanding of peptide signaling in the nervous system through the characterization of neuropeptides located in neurosecretory tissue of Cancer borealis and Cancer productus. Crabs are chosen for model systems in this work for their simplified nervous system yet employing a large diversity of neuropeptides. The characterization is accomplished in two ways; first using matrix assisted laser desorption/ionization Fourier transform mass spectrometry (MALDI FTMS) to obtain tissue specific peptide profiles directly from tissue, secondly, to screen HPLC separations of tissue homogenates pooled from multiple animals to locate and sequence abundant peptides. Also, the peptides released in the circulatory fluid, or hemolymph, are studied to discover changes brought about by changes in physiological conditions such as feeding and day and night cycles.
