From the Basic Science of Multimolecular Signaling Complexes to Novel Therapeutic Approaches For Heart and Eye Diseases
Specificity and efficacy in intracellular signal transduction can be conferred by the anchoring and co-localization of key enzymes and their upstream activators and substrate effectors by scaffold proteins. The Kapiloff lab investigates “signalosomes” formed by scaffold proteins, asking fundamental questions such as: 1) how are signalosomes constituted; 2) how are upstream signals integrated by signalosomes to regulate in a concerted manner downstream effectors; 3) what is the physiologic relevance of these signalosomes; and 4) can signalosomes be targeted in a clinically relevant manner so as to constitute new therapeutic strategies. In particular, the Kapiloff lab studies signaling within the myocardium and retina. Using a comprehensive approach that includes biochemistry, cell biology, and in vivo physiology, ongoing projects address the regulation of pathological cardiac remodeling and the effects of disease on retinal neurons. New gene therapy biologic drugs are being developed to treat ophthalmic diseases like glaucoma and cardiovascular diseases like heart failure.
