Expression of gonadotropin-releasing hormone and gonadotropin-releasing hormone receptor in sheep spinal cord.
Consistent with its neuroendocrine role, gonadotropin-releasing hormone (GnRH) is located principally within the hypothalamus, although extra-hypothalamic expression has been reported. The present study characterized the expression of GnRH and GnRH receptor (GnRH-R) in sheep spinal cord using real-time PCR and immunocytochemistry. Both GnRH and GnRH-R mRNA were detected in sheep spinal cord. Expression of GnRH peptide was localized to discrete locations in the spinal cord, including lamina X (the area surrounding the central canal) and motoneurons in the ventral horn. Although there is no known functional role for GnRH in spinal cord, a role as a potential neurotransmitter/neuromodulator is supported by the expression of both GnRH and GnRH-R in this tissue.
