Dr. Sahenk currently serves as Director of Clinical and Experimental
Neuromuscular Pathology at The Research Institute at Nationwide Childrens
Hospital and holds Professorships in Neurology and Pediatrics at the Ohio
State University. Dr. Sahenk’s laboratory focuses on basic and
translational studies related to peripheral nerve disorders. An important
goal has been testing therapeutic options to alleviate nerve dysfunction
in experimental studies in order to contribute pre-clinical data in support
of clinical trials.
Current research aims are to define the anatomical and
molecular basis of hereditary peripheral neuropathies, emphasizing the
role of trophic factors in nerve regeneration and regeneration-associated
myelination. The role of neurotrophin-3 as well as Trk receptor specific
agonistic antibodies in nerve regeneration in animal models of Charcot-Marie-Tooth
(CMT) is currently under investigation. In addition, the laboratory works
on projects involving the development of therapeutics and novel methods
to deliver therapeutic genes more efficiently to the peripheral nerves.
These studies are relevant to understanding the mechanism of axonal loss
and impaired regeneration in CMT disorders and developing rational therapies
to alleviate nerve dysfunction and promote nerve regeneration.
