| الوصف: | Hypothyroidism causes somatic, psychosocial and affective psychosis, including depression-like behaviors. In this study, (hypothyroidism group; HP group) adult male Sprague Dawley (SD) rats were induced to hypothyroidism after 5 weeks of exposure to 0.05% propylthiouracil (PTU) in potable water, control animals (CON group) were given the same amount of water. The following behavioral experiments were conducted, respectively: open-field test (OFT), forced swimming test (FST), tail suspension test (TST). TT[Formula: see text] and TT[Formula: see text] levels were measured after the behavior tests and the expression levels of 5-HT[Formula: see text] receptor and 5-HT[Formula: see text] receptor proteins were analyzed in the hippocampus and prefrontal cortex. The level of TT[Formula: see text] and TT[Formula: see text] in the HP group rats was much lower than that in the CON group. The hypothyroid rats also showed weight loss, much longer immobility time in tail suspension test and forced swimming test. Besides, 5 weeks of PTU administration was associated with significantly decreased expression levels of 5-HT[Formula: see text] receptor and 5-HT[Formula: see text] receptor proteins compared with control group, which were significantly negatively correlated with immobility time in FST and TST. In conclusion, our results suggest that hypothyroidism induces depressive behaviors through the influence of the serotonin system, and the decreased expression of the 5-HT[Formula: see text] receptor is an important cause of the depressive behaviors in hypothyroidism. |
