hypothesis, demonstrating that Dihexa, given by abdominal injection or orally, completely restored lost motor function. Moreover, staining for tyrosine hydroxylase (TH), a marker for the dopamine neurons that were lost following chemical lesioning, returned to near normal after 34 days of treatment. Studies are still ongoing to determine whether this recovery of TH staining was due to the presence of new nerve cells and/or the expansion of the appendages of surviving neurons.
