Pigment Epithelium-Derived Factor Peptides and Their Use for Treating Retinal Degeneration

Summary:  

The National Eye Institute (NEI) seeks research co-development partners and/or licensees for the development of an AAV2-based delivery system or an eyedrop formulation to deliver a Pigment Epithelium-Derived Factor (PEDF) peptide as a gene-agnostic approach to treating inherited retinal diseases. 

Electrochemical Impedance Spectroscopy (EIS) for Non-Destructive Assessment of Epithelial Integrity

This technology includes a novel apparatus and method that utilizes Electrochemical Impedance Spectroscopy (EIS) to assess the integrity of epithelial cell membranes non-destructively. By applying frequency-modulated voltage signals and facilitating fluid exchange on both sides of the epithelial tissue, this technology allows researchers to characterize membrane-specific responses with unprecedented accuracy.

Electrochemical Impedance Spectroscopy (EIS) Device to Resolve Individual Membrane Electrical Properties of Epithelial and Endothelial Tissues

Understanding the electrical properties of barrier tissues is crucial for deciphering their physiological functions and pathological conditions. These tissues, such as epithelial and endothelial layers, play critical roles in regulating the transport of ions, nutrients, and signaling molecules. By quantifying membrane-specific resistances, capacitances, and potentials, researchers gain valuable insights into epithelial development, barrier integrity, and disease progression.
