CGRP causes a transient increase in P2X 3 expression in the spinal trigeminal nucleus at 2 and 24 hours. Sections of spinal cord were obtained from control animals (CON), animals 2 hours post CGRP injections or animals 24 hours post CGRP injection. (A) Images of spinal cord tissues stained for P2X3 are shown in the top panels. Magnification bar = 50 μm. The same sections costained for P2X3 and DAPI are displayed in the bottom panels. (B) The average fold change ± SEM of P2X3 staining intensity from control values is reported (n = 3). * P < 0.05 when compared to control values.
