title: Altered levels of calcitonin gene-related peptide (CGRP)-like immunoreactivity of cat lumbar motoneurons after chronic spinal cord transection.
abstract: In cats subjected to total spinal cord transection at the lower thoracic level, the calcitonin gene-related peptide (CGRP)-like immunoreactivity (LI) was studied in motoneuron cell bodies in the L6-L7 segments. In transected animals, the CGRP-immunoreactive labeling of the motoneurons was virtually absent. When combining the spinal cord transection with a unilateral rhizotomy of all dorsal roots below the transection, however, an apparently normal labelling pattern of CGRP-LI of the motoneurons was displayed on both sides. Thus, surgical interventions which affect afferent pathways to the motoneurons may have influence on the levels of CGRP-LI in otherwise intact motoneurons.
