CAR-T免疫細(xì)胞療法—背景
十月底,諾華的CTL019之后,F(xiàn)DA公布Kite公司的Yescarta CAR-T免疫細(xì)胞療法成為FDA認(rèn)證的第二個(gè)基因療法。自從Emily Whitehead帶來(lái)癌癥治愈新希望后,CAR-T免疫細(xì)胞療法再次穩(wěn)固了它免疫細(xì)胞療法領(lǐng)域的中心地位。
CAR-T免疫細(xì)胞療法流程
1、從癌癥病人身上獲取T細(xì)胞。
2、利用基因工程技術(shù)給T細(xì)胞加入嵌合抗體。
3、體外培養(yǎng),大量擴(kuò)增CAR-T細(xì)胞。
4、擴(kuò)增好的CAR-T細(xì)胞輸回病人體內(nèi)。
CAR-T免疫細(xì)胞療法的T細(xì)胞來(lái)自外周血(PBMC)。臨床研究表明,T細(xì)胞進(jìn)行亞群分選后的CAR-T療效更好。諾華和Kite的 CAR-T 產(chǎn)品使用的都是固定比例的 CD4+/CD8+T 細(xì)胞4。
CAR-T免疫細(xì)胞療法—T細(xì)胞分選
用于CAR-T基因改造的人外周血T細(xì)胞的選擇依據(jù)1,2:
1.初始細(xì)胞比效應(yīng)細(xì)胞好。
Nature 3月的CAR-T綜述總結(jié)了選擇合適的人外周血T細(xì)胞亞群有利于臨床治療。
圖a:T細(xì)胞亞群的分化:TN到TCM細(xì)胞仍保有自我更新能力。選擇分化程度較低的初始T細(xì)胞(TN),記憶T細(xì)胞(TSCM或TCM)而不是分化末端的效應(yīng)T細(xì)胞用于基因改造可能會(huì)帶來(lái)更大治療效應(yīng)。
2.固定T細(xì)胞各亞群的比例
而由福瑞德·哈金森癌癥研究中心(Fred Hutchinson Cancer Research Center)主導(dǎo)的一項(xiàng)臨床實(shí)驗(yàn)的進(jìn)展是使用固定比例的CD4+/CD8+T細(xì)胞(NIH:NCT01865617,CD4:CD8=1:1)。
