Bio

Konstantin Feinberg, PhD, assistant research professor of surgery at the IU School of Medicine, is trained as a biochemist and molecular neurobiologist, with special emphasis on ligand-receptor interaction and cellular communication in the nervous system. Currently, as a co-PI together with Dr. Borschel. Dr. Feinberg’s current research is focusing on mechanisms of neuronal degeneration and regeneration, as well as the role of the corneal sensory innervation in regulation of Limbal stem cells – dependent corneal epithelial renewal.

During his graduate studies he has identified NrCAM as glial protein that, together with gliomedin, induces the clustering of sodium channels, as well as discovered the clues behind the node of Ranvier formation in the peripheral nervous system (Feinberg et al., Neuron 2010). During his postdoctoral training, he discovered how to generate functional Schwann cells from human skin-derived mesenchymal stem cells and demonstrated their potential to re-myelinate in Sciatic nerve injury rat model. For his postdoctoral training’s major project, Dr. Feinberg revealed a potent neuroprotective drug that could be repurposed for use as a therapeutic agent for nerve injuries and neurodegeneration and used this drug to identify a previously unknown pro-degenerative feature of a neurotrophic receptor TrkA in sympathetic and sensory neurons (Feinberg et al., 2018 JCB).
