Dr. Diane Shelton

  • Diane Shelton, D.V.M, PhD, DACVIM, is a graduate of the UC Davis School of Veterinary Medicine, completed an internship in small animal medicine and surgery at Michigan State University and a residency in small animal internal medicine at the University of Pennsylvania. She completed a PhD in Comparative Pathology at UC Davis followed by a post-doctoral fellowship at the Salk Institute for Biological Studies, La Jolla, CA in the laboratory of Dr. Jon Lindstrom, with an emphasis on experimental and naturally occurring models of myasthenia gravis. In 1990, Dr. Shelton established the Comparative Neuromuscular Laboratory (CNL) in the School of Medicine, UC San Diego, an international reference center for the study of spontaneously occurring neuromuscular diseases in companion animals. Currently she is Director of the CNL and Professor, Department of Pathology at UCSD.

About the Laboratory

  • Welcome to the Comparative Neuromuscular Laboratory located in the School of Medicine at the University of California, San Diego. This laboratory, established in 1990, is an international reference center dedicated to the diagnosis and study of spontaneous neuromuscular diseases in companion animals. Specialized testing performed in this laboratory includes evaluation of muscle and peripheral nerve biopsies by state-of-the-art methods, immunohistochemistry, immunofluorescence staining and immunoblotting for the diagnosis of various muscular dystrophies and other congenital myopathies.
