Research Interests
  • Myelination: Dr. Popko's laboratory has a long-standing interest in the glial cells of the nervous system, particularly in those responsible for the formation of the myelin sheath. These interests range from a basic understanding of the myelination process to disease mechanisms, genetic and acquired, that disrupt this critical component of the nervous system. The genetic mouse models utilized by the Popko lab have been instrumental in expanding knowledge of the myelination process and of demyelinating disorders. Over the past two decades, Dr. Popko's studies have contributed to our understanding of myelin-specific proteins and lipids that play critical roles in myelin formation and maintenance. His lab also has a keen interest in the effect of the inflammatory response on myelinating cells, which is of critical importance to the pathogenesis of immune-mediated demyelinating disorders.
  • Peripheral Neuropathy: Dr. Popko is pursuing a better understanding of the molecules that are important to the development and maintenance of the peripheral nerve, again using mouse models as a key resource. The underlying hypothesis of this work is that the identification of susceptible pathways that have the potential to lead to peripheral nerve disorders in mice will be of practical value in the understanding of human peripheral neuropathies and in the assessment of prospective therapeutic approaches. Dr. Popko's efforts include the characterization of mutant and transgenic strains of mice with behavioral, physiological, histological, biochemical, and molecular approaches.
  • Dr. Popko's work has consistently been funded by the National Institutes of Health. His laboratory is also one of four participating laboratories funded by the private, non-profit Myelin Repair Foundation, which is devoted to promoting functional recovery in multiple sclerosis patients.
