Stereotaxic Surgical Targeting of the Nonhuman Primate Caudate and Putamen: Gene Therapy for Huntington's Disease.

Stereotaxic surgery is an invaluable tool to deliver a variety of gene therapy constructs to the nonhuman primate caudate and putamen in preclinical studies for the genetic, neurodegenerative disorder, Huntington's disease (HD). Here we describe in detail how to perform this technique beginning with a pre-surgical magnetic resonance imaging scan to determine surgical coordinates followed by the stereotaxic surgical injection technique. In addition, we include methodology of a full necropsy including brain and peripheral tissue removal and a standard immunohistochemical technique to visualize the injected gene therapy agent.
