Galanin- and CGRP-like immunoreactivity coexist in rat spinal motoneurons.
We can report, that by the use of indirect immunofluorescence techniques, that rat spinal motoneurons contain galanin-like immunoreactivity (LI). Furthermore, that galanin and calcitonin gene-related peptide (CGRP)-LI coexist in a number of spinal motoneurons. Co-localization could be demonstrated as thoracic, lumbar as well as sacral spinal cord levels in individual neurons by studying adjacent sections each stained by one of the two antisera, as well as by double labelling experiments. Small neurons, within the gamma-motoneuron and interneuron size-range, were also positive for galanin-LI.
