GDNF and spinal cord injury: For instance, Sliwinski et al. (16) referenced Detloff’s article “Acute Exercise Prevents the Development of NP and the Sprouting of Non-peptidergic (GDNF- and Artemin-responsive) C-fibers After Spinal Cord Injury.” Liu et al. (17) cited Detloff’s article, “Exercise-Induced Changes to the Macrophage Response in the Dorsal Root Ganglia Prevent Neuropathic Pain after Spinal Cord Injury.” Lee et al. (18) also referred to Detloff’s article, “Chronic at- and Below-level Pain After Moderate Unilateral Cervical Spinal Cord Contusion in Rats.”
