Characterization of a Novel Caveolin Modulator That Reduces Vascular Permeability and Ocular Inflammation

Purpose: Caveolin (Cav) regulates various aspect of endothelial cell signaling and cell-permeable peptides (CPPs) fused to domains of Cav can reduce retinal damage and inflammation in vivo. Thus, the goal of the present study was to identify a novel CPP that improves delivery of a truncated Cav modulator in vitro and in vivo. Methods: Phage display technology was used to identify a small peptide (RRPPR) that was internalized into endothelial...
