CAR-T 药物非临床体内药效学研究常用的模型有哪些

世界杯申办官网已建立完善的药效学研究模型与技术体系，可从整体、细胞、分子及基因等多个层面系统评价新药的药效，并解析其作用机制。常规开展的研究领域包括抗肿瘤药物、心血管系统药物、抗炎药物及降血糖药物等的药效学评价，同时涵盖生物技术药物的相关研究。

药效学研究的一般原则为随机、对照、重复；其基本方法包括体内试验法和体外试验法，其中新药药效学试验以体内试验为主、体外试验为辅。

Droxytryptamine (5-HT; serotonin) 5-HT3 receptor is an excitatory ligandgated ion channel expressed in for example the brain and the gastrointestinal tract. CSTI-300 as a selective, high affinity 5-HT3 receptor partial agonist. CSTI-300 was examined alongside the selective 5-HT3 receptor antagonist alosetron (which is also currently marketed as a therapeutic for IBS-d). Sub-cutaneous application of 5-hydroxytryptophan (5-HTP; 10 mg/kg) markedly increased the rat’s sensitivity to abdominal contractions. CSTI-300 and Alosetron displayed similar efficacy in a rodent in vivo model of IBS-d, measured by a reduction in colonic sensitivity. The experiments (Rat colon distension model of IBS-d) were carried out by Medicilon. The protocol complied with and was approved by the Institutional Animal Care and Use Committee and Medicilon is accredited by the NIH Office of laboratory Animal Welfare (OLAW) and AAALAC. Experiments (dog behavioural and emesis model) were performed by Medicilon. The protocol for the dog behavioural and emesis model complied with and was approved by the Institutional Animal Care and Use Committee.
