Eyes :: Receptor that enables clear corneas is identified
The cornea stays clear by expressing a soluble form of a receptor that traps factors enabling growth of vision-obstructing blood vessels, researchers say. When sflt-1, a free-floating receptor for vascular endothelial growth factor A, is eliminated, vision-obstructing blood vessels start growing, teams of researchers led by the Medical College of Georgia and University of Kentucky report in Nature. The paper was published online Oct. 18 and will be in the Oct. 26 print issue.
