摘要:
(FXS)是遗传智障(ID)的最常见形式和自闭症谱系障碍(ASD)的主要单基因原因。血清素能神经传递在发育过程中神经元活性的调节中具有关键作用,因此,它已被认为参与了包括FX在内的ASD和同时发生条件。由于5-羟色胺参与ED在突触重塑和成熟过程中,儿童时期的血清素能不足可能对神经发育障碍中的脑模式产生更大的影响,表现为行为和情感症状。 Thus, compounds that stimulate serotonergic signaling such as psilocybin may offer promise as effective early interventions for developmental disorders such as ASD and FXS.
OBJECTIVES: The aim of the present study was to test whether different protocols of psilocybin administration mitigate cognitive deficits displayed by the recently validated Fmr1-exon 8 rat model of ASD, which is also a model of FXS.
RESULTS: Our results revealed that systemic and oral administration of psilocybin microdoses normalizes the aberrant cognitive performance displayed by adolescent Fmr1-exon 8 rats in the short-term version of the新颖的对象识别测试 - 探索行为,感知和认可。
