[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 ...

[Abstract] Multiple viruses can co-infect the genital tract, modifying the immunologic and virologic milieu and possibly playing a role in viral transmission and pathogenesis. The aim of our studies has been to understand the complex relationships between HIV-1 RNA, and multiple human herpesviruses known to frequently replicate in the genital tract of HIV-infected men (i.e. cytomegalovirus [CMV], Epstein Bar virus [EBV], herpes simplex virus [HSV] types 1 and 2, and human herpesviruses [HHV] 6, 7 and 8) (Gianella et al., 2013a; Gianella et al., 2013b; Gianella et al., ...
[摘要] 多种病毒可以共感染生殖道，修改免疫学和病毒学环境，并可能在病毒传播和发病中起作用。 我们的研究的目的是了解HIV-1 RNA和已知在HIV感染的男性生殖道中经常复制的多种人疱疹病毒之间的复杂关系（即巨细胞病毒[CMV]，Epstein 条形病毒[EBV]，单纯疱疹病毒[HSV] 1型和2型，以及人疱疹病毒[HHV] 6,7和8）（Gianella等人，2013a; Gianella等人 。，2013b; Gianella 等人，2013c; Gianella ，2014）。 该方案设计用于收集和处理男性生殖器分泌（GS），并使用定量实时PCR技术从精浆中分离并进一步定量7个HHV的HIV RNA和DNA。

[Abstract] This ChIP protocol was developed and improved over the years by various researchers in the Snyder lab, Stanford University, especially Anthony Borneman and Christopher Yellman. I have used this method to successfully map the genome-wide binding of transcription factors Ste12. The ChIPed DNA is suitable for downstream analysis using PCR, microarray or sequencing.
[摘要] 本篇 ChIP 的方法是Snyder实验室多年来经多位学者改进优化而来，特别是 Anthony Borneman 和 Christopher Yellman。我应用此方法已成功定位了转录因子Ste12在基因组范围内的结合。ChIP得到的DNA可通过PCR、芯片及测序进行下游的分析。
