Research Abstract:

The overall focus of the Mackinnon Peripheral Nerve Research Laboratory is to investigate the pathology, mechanisms, and current/prospective clinical treatments of peripheral nerve injury. The laboratory utilizes models of peripheral nerve injury in combination with quantifiable assessment via in vivo imaging, histomorphometry, confocal microscopy, muscle force output and walking gate analysis to evaluate nerve regeneration. The results from this research are used to test prospective clinical treatments and provide insights into biological processes of nerve regeneration. The work from the lab has led directly to changes in the clinical treatment of patients with peripheral nerve injury and to new understanding of nerve regeneration. Currently our laboratory is evaluating the regenerative capacity of acellular nerve allografts and methods, such as endogenous Schwann cell transplantations, to enhance regeneration in the nerve allografts. Additionally our lab is utilizing targeted up regulation of GDNF in denervated skeletal muscle via viral drug delivery to investigate the parameters of GDNF delivery in the periphery that enhance peripheral nerve regeneration.
