Insulin Releasing Properties of the Temporin Family of Antimicrobial Peptides
Abstract:Temporin-1Vb, -1Oe, -1DRb, and -1TGb (10-8 - 10-6M) produced significant (p<0.05) and concentrationdependent stimulatory effects on insulin secretion from clonal rat BRIN-BD11 cells without increased release of lactate dehydrogenase. Temporin-1Va and temporin-1Vc (10-8 - 10-6M) also stimulated insulin-release but were cytotoxic at 10-6M. Temporin-1DRa was without effect. The temporins at 10-7 M had no effect on intracellular calcium concentrations suggesting that they stimulate insulin release via a KATP channel- independent pathway.

- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
