Boosting the Immune System–
Steps to Take for Successful Substrate Delivery
嵌合抗原受體表達(dá)細(xì)胞的產(chǎn)生和基于CRISPR/Cas9的基因組編輯等新技術(shù)的建立,為改善或增強(qiáng)免疫應(yīng)答提供了簡(jiǎn)便易行的方案。然而,將底物輸送到我們的目的細(xì)胞中是需要的-不僅要注重高轉(zhuǎn)染效率,而且要注重細(xì)胞活性、功能性的保存以及患者的健康和安全。此外,傳遞方法在底物方面應(yīng)該是靈活的,因?yàn)榫庉嫾?xì)胞基因組的研究人員不僅依賴于質(zhì)粒DNA的成功轉(zhuǎn)染,還依賴于RNA和/或蛋白質(zhì)的成功轉(zhuǎn)染[1]。
到目前為止,原代免疫細(xì)胞的轉(zhuǎn)染是具有挑戰(zhàn)性的。特別是大家感興趣的細(xì)胞類型,如T淋巴細(xì)胞、自然殺傷細(xì)胞和B細(xì)胞,用經(jīng)典的基于試劑的方法很難轉(zhuǎn)染[2]。使用轉(zhuǎn)染試劑的主要問(wèn)題是轉(zhuǎn)染效率低、細(xì)胞毒性和免疫原性。后者在免疫治療方面是不利的,因?yàn)榧?xì)胞應(yīng)該維持它們?cè)诿庖呦到y(tǒng)中的功能,而不是被轉(zhuǎn)染方式預(yù)先激活。
實(shí)現(xiàn)合理轉(zhuǎn)染效率的替代方法是病毒轉(zhuǎn)導(dǎo),但病毒生產(chǎn)耗時(shí)且成本高,另一種方案是改進(jìn)的電穿孔技術(shù),如NucleofectorTM技術(shù),作為一種物理的方法,它只需要很低的生物安全預(yù)防措施(表1)。
