Natriuretic peptide system in the human retina.

Abstract

Our finding that NP receptor transcripts are expressed along with ANP, BNP, and CNP mRNA in the human retina provides evidence for a local system in this tissue. The expression of NPs in neural retinal, glial, and vascular elements of the normal adult retina suggests a role for these peptides in maintaining both the neural and vascular integrity of the mature retina.
