Differentiation of Myeloid-derived Suppressor Cells from Murine Bone Marrow and Their Co-culture with Splenic Dendritic Cells

[Abstract]  Myeloid-derived suppressor cells (MDSCs) possess the ability to suppress the immune response, and to amplify the regulatory properties of other immune cells, i.e., dendritic cells. Here we describe a protocol in which MDSCs were differentiated from murine bone marrow cells, and CD11c+ dendritic cells were purified from murine spleens. MDSCs and CD11c dendritic cells can be co-cultured and the immunoregulatory phenotype of the MDSCs-conditioned dendritic cells could be assessed by means of a specific functional in vivo experiment, i.e., a skin test as a ... [摘要]  骨髓来源的抑制细胞(MDSCs)具有抑制免疫应答的能力,并扩增其他免疫细胞即树突状细胞的调节特性。 在这里,我们描述了MDSC与鼠骨髓细胞分化的方案,并且从鼠脾中纯化CD11c +树突状细胞。 可以共培养MDSC和CD11c树突状细胞,并且可以通过特定的功能体内实验来评估MDSCs条件树突细胞的免疫调节表型,即皮肤试验作为延迟型超敏反应的量度 抗免疫原性较差的抗原。
【背景】骨髓来源的抑制细胞(MDSCs)是由早期分化阶段的巨噬细胞,粒细胞,树突状细胞和骨髓细胞的前体组成的骨髓细胞组(Youn等人,2008),其在肿瘤的淋巴组织中大量积累感染性小鼠以及感染性疾病,败血症和创伤的小鼠。这些细胞的主要特征是它们以Ag特异性和/或非特异性方式抑制T细胞应答的能力。这些细胞现在被认为是负责肿瘤相关免疫缺陷的主要细胞类型之一;涉及MDSC介导的免疫抑制的主要因素包括Arg1的高表达(Marvel和Gabrilovich,2015)。精氨酸酶1(Arg1)和吲哚胺2,3-双加氧酶1(IDO1)分别是催化L-精氨酸(L-Arg)和L-色氨酸(L-Trp)降解的免疫调节酶,导致局部氨基酸剥夺。此外,与Arg1不同,IDO1在树突细胞(DC)中也具有非酶信号传导活性(Mondanelli等,2017)。除了其固有的免疫抑制活性外,MDSC还可能扩增其他免疫细胞的调节特性,特别是在肿瘤微环境中。虽然建立了MDSC-巨噬细胞相互作用的一些机制(Ugel等,2015),MDSCs和DCs之间的串扰仍然不清楚(Ostrand-Rosenberg等,2012);为弥补这一差距,我们已经制定了该方案,并且我们证明了Arg1 ...

Teratoma Formation Assay for Assessing Pluripotency and Tumorigenicity of Pluripotent Stem Cells

[Abstract]  Pluripotent stem cells such as induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) form teratomas when transplanted into immunodeficient mice. As teratomas contain all three germ layers (endoderm, mesoderm, ectoderm), teratoma formation assay is widely used as an index of pluripotency (Evans and Kaufman, 1981; Hentze et al., 2009; Gropp et al., 2012). On the other hand, teratoma-forming tumorigenicity also represents a major risk factor impeding potential clinical applications of pluripotent stem cells (Miura et al., 2009; Okano et al., ... [摘要]  多能干细胞,如诱导多能干细胞(iPSCs)和胚胎干细胞(ESC),当移植到免疫缺陷小鼠时,形成畸胎瘤。由于畸胎瘤包含所有三个胚层(内胚层,中胚层,外胚层),畸胎瘤形成测定被广泛用作多能性的指标(Evans和Kaufman,1981; Hentze等,2009; Gropp等,2012)。另一方面,畸胎瘤形成致瘤性也是阻碍多能干细胞潜在临床应用的主要危险因素(Miura et al。,2009; Okano等,2013)。最近,我们报道了由于ES细胞表达的Ras(ERAS)和替代物,嫁接到非肥胖型糖尿病/严重联合免疫缺陷型(NOD / SCID)小鼠的睾丸中,从裸鼠睾丸衍生的iPSC缺乏畸胎瘤形成致瘤性阅读框(ARF)依赖于该物种特异性的肿瘤抑制机制(Miyawaki等,2016)。在这里,我们描述了将多能干细胞移植到NOD / SCID小鼠的睾丸中以产生用于评估多能性和致瘤性的畸胎瘤的方法。
【背景】iPSCs和ESC用于再生医学细胞移植治疗中的应用。然而,当移植到免疫缺陷小鼠中时,这些细胞形成称为含有分化组织的畸胎瘤的肿瘤。因此,其畸胎瘤形成致瘤性的风险限制了其临床应用。几项研究报道了克服畸胎瘤形成肿瘤发生风险的方法(Itakura et al。,2017; Vazquez-Martin et ...

Efficient Production of Functional Human NKT Cells from Induced Pluripotent Stem Cells − Reprogramming of Human Vα24+iNKT Cells

[Abstract]  Antigen-specific T cell-derived induced pluripotent stem cells (iPSCs) have been shown to re-differentiate into functional T cells and thus provide a potential source of T cells that could be useful for cancer immunotherapy. Human Vα24+ invariant natural killer T (Vα24+iNKT) cells are subset of T cells that are characterized by the expression of an invariant Vα24-Jα18 paired with Vβ11, that recognize glycolipids, such as α-galactosylceramide (α-GalCer), presented by the MHC class I-like molecule CD1d. Vα24+iNKT cells capable of producing IFN-γ are reported to ... [摘要]  抗原特异性T细胞来源的诱导多能干细胞(iPSCs)已显示重新分化为功能性T细胞,从而提供可用于癌症免疫治疗的T细胞的潜在来源。不变性自然杀伤T(Vα24 + iNKT)细胞的人Vα24 + 细胞是T细胞的子集,其特征在于与Vβ11配对的不变Vα24-Jα18的表达,其识别糖脂,如α-半乳糖神经酰胺(α-GalCer),由MHC I类分子CD1d呈递。据报道能够产生IFN-γ的Vα24 + i / KT细胞增加抗肿瘤反应,其影响NK细胞和CD8 +细胞毒性T淋巴细胞以消除MHC - 和MHC + 肿瘤细胞。在这里,我们描述了将人Vα24 + iNKT细胞重编程到iPSC中的鲁棒方案,然后将其重新分化为Vα24 + iNKT细胞(iPS-Vα24功能的iNKT)。我们进一步提供了测定iPS-Vα24 + iNKT细胞活性的方案。背景 以前有报道说,针对晚期非小细胞肺癌(NSCLC)和头颈部癌症的Vα24 + iNKT细胞癌免疫治疗的临床试验显示疗效,耐受性良好(Motohashi et al。等人,2009; Yamasaki等人,2011)。然而,已知来自外周血单核细胞(PBMC)的Vα24 ...
