Vampire bats could hold the key to new treatments for a range of serious medical problems, but researchers have hit a snag accessing the specimens needed to advance their work.

An international team led by The University of Queensland has found a new class of blood pressure-regulating peptides in the venom of the common vampire bat (Diphylla ecaudata).

UQ School of Biological Sciences researcher Associate Professor Bryan Fry said the peptides could help revolutionise treatments for a wide range of conditions, including hypertension, heart failure, kidney diseases and burns, but the research had been hampered by criminal activity at a Mexican field site.

"The peptides are mutated forms of the Calcitonin Gene Related Peptide (CGRP), used by our bodies to relax blood vessels," he said.

"The peptides from the bats are unusually selective in their mode of action, making them even more therapeutically useful than the CGRP, as they have fewer side-effects.

"This could potentially help doctors in the treatment of a range of disorders featuring heightened pressure in small blood vessels, or may be able to improve blood flow to damaged or transplanted tissue such...
