New discovery could reverse tissue damage caused by heart attacks

A new discovery by University of Bristol scientists helps to explain how cells which surround blood vessels, called pericytes, stimulate new blood vessels to grow with the hormone ‘leptin’ playing a key role. Leptin is produced by fat cells which helps to regulate energy balance in the body by inhibiting the appetite. This study, described in Scientific Reports, may have important implications for the treatment of heart attacks and also for cancer, the two main killers in the UK.
