synthesis and growth in Octopus vulgaris
Growth and Food Intake Models in Octopus Vulgaris ..
Serin protease inhibitor (SERPIN) proteins are important elements of the host defense to inactivate proteases secreted by pathogens and restrict their invasion , . Protease inhibitors have been found in Crassostrea virginica, C. gigas, Chlamys farreri and Ruditapes philippinarum, but have not been described in cephalopods. A total of 6 transcripts corresponding to SERPIN were putatively identified in the O. vulgaris library. Biochemical, functional and molecular characterization of SERPIN is needed to understand whether and how the octopus’ hemocytes use this protein to counteract coccidiosis.

Antimicrobial peptides are proteins with the broad ability to kill or neutralize Gram-negative and Gram-positive bacteria, fungi, parasites or viruses, interacting with and crossing cell envelope membranes by a multihit mechanism . The bactericidal permeability-increasing protein (BPI) is an AMP produced by polymorphonuclear leukocytes, but also by epithelial cells. Mucosal epithelia that co-exist with microbes and microbial products expressing BPI probably contribute to the maintenance of immunologic homeostasis at mucosal surfaces . At least three light-organ proteins in the BPI/LBP (lipopolysaccharide-binding protein) family have been sequenced from E. scolopes. A single transcript of the BPI protein is provided in this O. vulgaris library. Additional studies are needed to understand the role of this protein in the octopus cellular defense.
