Age-related changes in levels of calcitonin gene-related peptide (CGRP) mRNA of the dorsal root ganglia was studied in 8-, 12- and 15-week-old spontaneously hypertensive rats (SHR) and age-matched normotensive Wistar Kyoto rats (WKY). CGRP mRNA levels in SHR but not in WKY decreased with age. The contents of CGRP-like immunoreactivities in the atrium and mesenteric artery of 15-week-old SHR were greater than those in age-matched WKY. These results suggest that the outflow of CGRP-containing nerves from the spinal cord and CGRP release from CGRP nerve terminals decreases in SHR.
