Expression of MT1 and MT2 genes in rat TG, SPG and hypothalamus. ( A ) Comparison of MT1 and MT2 mRNA levels in the TG of male and female rats shows that MT1 expression is significantly higher than MT2. ( B ) In both the hypothalamus (HT) and SPG of male rats, MT1 mRNA levels are also significantly higher than MT2. Data are presented as mean ± SEM, statistical significance indicate as *** p < 0.001, ** p < 0.01, * p < 0.05, and n = 6

MT1 and MT2 immunoreactivity in TG. ( A ) positive MT1 immunoreactivity was observed in the cytoplasm and nuclei of TG neurons (thick arrows) and in SGCs (arrowheads). ( B ) MT2 immunoreactivity was observed predominantly in the cytoplasm of neurons (thick arrows), in some cases in their nuclei (thick arrows), and in Aδ-fibers (thin arrows). Negative cells are indicated by asterisks in both ( A ) and ( B ). Blue color represents nuclei staining with DAPI. ( C ) Bar graphs show the number of MT1 and MT2 immunoreactive TG neurons in male and female rats. There was no significant difference in MT1 or MT2 protein expression between sexes. However, the number of MT1-immunoreactive cells was approximately twofold higher than that of MT2 in both males and females. Data are presented as the mean ± SEM, n = 6 and * p < 0.05

Double immunohistochemistry of MT2 with CASPR and CGRP in rat dura mater. ( A and D ) Thin MT2-immunoreactive axons (green, arrows) were observed in the rat dura mater. ( B ) These fibers were identified as Aδ-fibers based on CASPR immunoreactivity (red) showing the characteristic bowtie-shaped paranodal pattern (arrowheads). ( A - C ) Fiber bundles were often seen flanking dural blood vessels (asterisks). ( C ) MT2 and CASPR were observed to be co-expressed in the same Aδ-fibers. ( E ) CGRP immunoreactivity (red, arrowheads) was detected in c-fibers throughout the rat dura mater in a granular, pearl-like pattern. ( F ) Merged images show intertwined C- and Aδ-fibers, expressing CGRP and MT2 respectively, projecting throughout the dura mater
