文献和实验Cytotoxic Tlymphocyte 4(CTLA-4,CD152), is a type I transmembrane T cell inhibitory molecule that is a member of the Ig superfamily.CD28 and CTLA-4, together with their ligands, B7-1 and B7-2, constitute one of the dominant costimulatory pathways that regulate T and B cell responses. CD28 and CTLA-4 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T Cells and may play an important role in their functions. Tcell activation through the Tcell receptor and CD28 leads to increased expression of CTLA4.
豚鼠(Guine-pig;Cavia porcellus) 一、生物学特性和解剖生理特点 1.豚鼠属哺乳纲,啮齿目,豚鼠科。又名天竺鼠、海猪、荷兰猪。 2.喜群居,头大,颈短、耳圆、无尾,全身被毛,四肢较短,前肢有四趾,后肢有三趾,有尖锐短瓜,有抓人,不喜于攀登和跳跃,故可放无盖小水泥池中进行饲养。习性温顺,胆小易惊,有时发出吱吱的尖叫声,喜干燥清洁的生活环境。 3.嗅觉、听觉较发达,对各种刺激均有极高的反应
豚鼠(Guine-pig;Cavia porcellus)--生物学特性和解剖生理特点
网络 第三节 豚鼠(Guine-pig;Cavia porcellus) 一、生物学特性和解剖生理特点 1.豚鼠属哺乳纲,啮齿目,豚鼠科。又名天竺鼠、海猪、荷兰猪。 2.喜群居,头大,颈短、耳圆、无尾,全身被毛,四肢较短,前肢有四趾,后肢有三趾,有尖锐短瓜,有抓人,不喜于攀登和跳跃,故可放无盖小水泥池中进行饲养。习性温顺,胆小易惊
动物。其性情较温顺。受惊时表现凶狠,易咬人。大白鼠的嗅觉灵敏,对噪音敏感,而且对营养缺乏也非常的敏感。由于大白鼠繁殖力强,易饲养,体型大小合适,给药容易,采样量合适方便,故在医学实验中的用量仅次于小鼠。适合作药物和肿瘤学研究。 3. 豚鼠(guinea pig, cavia porcellus) 豚鼠又名海猪、天竺鼠、荷兰猪。属哺乳纲,啮齿目,豪猪形亚目,豚鼠科,豚鼠鼠动物。其性情温驯,胆小怕惊。很少咬人或抓手。由于豚鼠的迟发性超敏反应与人类相似,所以豚鼠是过敏性休克和变态反应研究的首选动物
