Methods for increasing the selective efficacy of gene therapy using car peptide and heparan-sulfate mediated macropinocytosis

Abstract

Disclosed are compositions and methods for triggering disease selective macropinocytosis. The compositions can serve as a marker of disease activity and as a trigger of enhanced macropinocytosis in tissues undergoing disease remodeling such as wound healing, cancer, PAH, inflammation, diabetes, Crohn's disease, ulcerative colitis, ankylosing spondylitis, diseases of the endometrium, psoriasis, irritable bowel syndrome, arthritis, fibrotic disorders, interstitial cystitis, autoimmune diseases, asthma, acute lung injury, and adult respiratory distress syndrome. The compositions can also serve as a receptor for disease selective cell penetrating peptides in the cells and extracellular matrix of diseased tissues.
