The present experiments tested the hypothesis that one of the critical mechanisms underlying genetically defined aggressiveness involves brain serotonin 5-HT1A receptors. 5-HT1A receptor density, the receptor mRNA expression in brain structures, and functional correlates for 5-HT1A receptors identified as 8-OH-DPAT-induced hypothermia and lower lip retraction (LLR) were studied in Norway rats bred for 59 generations for the lack of aggressiveness and for high affective aggressiveness with respect to man. Considerable differences between the highly aggressive and the nonaggressive rats were shown in all three traits. A significant decrease in B(max) of specific receptor binding of [3H]8-OH-DPAT in the frontal cortex, hypothalamus, and amygdala and a reduction in 5-HT1A receptor mRNA expression in the midbrain of aggressive rats were found. 5-HT1A receptor agonist 8-OH-DPAT (0.5 mg/kg, i.p.) produced a distinct hypothermic reaction in nonaggressive rats and did not affect significantly the body temperature in aggressive rats. Similar differences were revealed in 8-OH-DPAT-induced LLR: LLR was expressed much more in nonaggressive than in aggressive animals. Additionally, 8-OH-DPAT (0.5 mg/kg i.p.) treatment significantly attenuated the aggressive response to man. The results demonstrated an association of aggressiveness with reduced 5-HT1A receptor expression and function, thereby providing support for the view favoring the idea that brain HT1A receptor contributes to the genetically defined individual differences in aggressiveness. 相似文献

Results of pathomorphological studies of 133 amyloidosis cases in macaques of 3 species (M. mulatta, M. nemestrina, and M. fascicularis) in the Adler Primatological Center are presented. A relationship between the development of amyloidosis and animal age is detected and the incidence of involvement of various organs is determined. Generalized and isolated forms of amyloidosis are described, the most incident of which (36.8%) was hepatic amyloidosis. Simian and human amyloidosis are compared. Amyloidosis in macaques can be used as the model process for studies of amyloidosis in humans. 相似文献
