To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

树突状细胞来做为瘤苗。(5)与细胞因子联合使用:IL12是体内介导TH1型应答的细胞因子,与抗原冲击的树突状细胞瘤苗联合应用于肿瘤治疗,收到更佳的抗癌效果。某些情况下甚至逆转由树突状细胞诱导的耐受。肿瘤相关抗原和肿瘤特异性抗原:粒细胞、巨噬细胞集落刺激因子(GMCSF)可以促进树突状细胞的成熟,维持树突状细胞的存活。 将GMCSF基因经腺病毒载体介导转入树突状细胞,具有更强的体内激发肿瘤特异性CTL的能力。用腺病毒将IL12基因转染树突状细胞,也可协同增强T细胞功能,促进机体的抗肿瘤效应。Fms
应该比任何方法都有效,因为每一步都切中要害,每一步周到得滴水不漏。 4、不含GM-CSF和IL-4的培养基先培养数小时? 我们都知道GM-CSF是诱导DC分化、生长和发育的。那么为什么一开始要用不含GM-CSF培养3 小时, 甚至几十小时后,再加GM-CSF呢?这样骨髓细胞已经向其他方向分化了,难道再用GM-CSF可以把粒细胞或巨噬细胞“逆分化”成DC吗?有如:我们在十字路口明明是要向右转,却一定要先向左转开一段路,再180度掉头向后转呢?就如我在第1点中说的,非要把DC细胞折腾到濒临
