NET is also commonly called uptake 1 or reuptake 1 and is partially responsible for the termination of synaptic activity. NET can be inhibited by cocaine and certain antidepressant drugs, resulting in an increase of transmitter activity in the synaptic cleft 【延伸學習 & 國考複習】 (北醫藥學103級藥理藥化統整本 3.0 P38...

【評論內容】(B) Cannabinoid 大麻素▲萜酚類化合物,自然存在於動物神經和免疫系統裡。◻︎   內源性大麻素 Endocannabinoids      ✓ 主要有兩種:AEA(anandamide)(花生四烯乙醇胺)與 2-AG(2-Arachidonoylglycerol)        ✓ 由人體內的細胞自然生成。◻︎   植物性大麻素:四氫大麻酚 THC(Tetrahydrocannabinol)        ✓  Cannabinoid 的延伸結構、大麻的活性成分。▲   機轉:神經元的去極化會造成後突觸神經元的鈣離子濃度上升,此濃度變化會誘發突觸後細胞合成與釋放內源性大麻素。內源性大麻素和突觸前細胞的 CB1R 結合後,會抑制 GABA 的釋放,降低抑制性神經傳導。▲   兩種中樞...
