Due to the limitations of autologous chimeric antigen receptor (CAR)-T cells, alternative sources of cellular immunotherapy, including CAR macrophages, are emerging for solid tumors. Human induced pluripotent stem cells (iPSCs) offer an unlimited source for immune cell generation. Here, we develop human iPSC-derived CAR macrophages targeting prostate stem cell antigen (PSCA) (CAR-iMacs), which express membrane-bound interleukin (IL)-15 and truncated epidermal growth factor receptor (EGFR) for immune cell activation and a suicide switch, respectively. These allogeneic CAR-iMacs exhibit strong antitumor activity against human pancreatic solid tumors in vitro and in vivo, leading to reduced tumor burden and improved survival in a pancreatic cancer mouse model. CAR-iMacs appear safe and do not exhibit signs of cytokine release syndrome or other in vivo toxicities. We optimized the cryopreservation of CAR-iMac progenitors that remain functional upon thawing, providing an off-the-shelf, allogeneic cell product that can be developed into CAR-iMacs. Overall, our preclinical data strongly support the potential clinical translation of this human iPSC-derived platform for solid tumors, including pancreatic cancer.

由于自体嵌合抗原受体(CAR)-T 细胞的局限性,包括 CAR 巨噬细胞在内的细胞免疫疗法替代来源正在出现,用于实体瘤的治疗。人类诱导多能干细胞(iPSC)为免疫细胞的生成提供了无限的来源。在这里,我们开发了针对前列腺干细胞抗原(PSCA)的人iPSC衍生CAR巨噬细胞(CAR-iMacs),它们表达膜结合白细胞介素(IL)-15和截短的表皮生长因子受体(EGFR),分别用于激活免疫细胞和自杀开关。这些异体 CAR-iMacs 在体外和体内对人类胰腺实体瘤表现出很强的抗肿瘤活性,在胰腺癌小鼠模型中减轻了肿瘤负担,提高了生存率。CAR-iMacs 看起来很安全,没有细胞因子释放综合征或其他体内毒性症状。我们优化了 CAR-iMac 祖细胞的冷冻保存,使其在解冻后仍能保持功能,从而提供了一种现成的异体细胞产品,可以开发成 CAR-iMacs。总之,我们的临床前数据有力地支持了这一人类 iPSC 衍生平台用于实体瘤(包括胰腺癌)的潜在临床转化。

Alveolar epithelial type I cells (AT1s) line the gas exchange barrier of the distal lung and have been historically challenging to isolate or maintain in cell culture. Here, we engineer a human in vitro AT1 model system via directed differentiation of induced pluripotent stem cells (iPSCs). We use primary adult AT1 global transcriptomes to suggest benchmarks and pathways, such as Hippo-LATS-YAP/TAZ signaling, enriched in these cells. Next, we generate iPSC-derived alveolar epithelial type II cells (AT2s) and find that nuclear YAP signaling is sufficient to promote a broad transcriptomic shift from AT2 to AT1 gene programs. The resulting cells express a molecular, morphologic, and functional phenotype reminiscent of human AT1 cells, including the capacity to form a flat epithelial barrier producing characteristic extracellular matrix molecules and secreted ligands. Our results provide an in vitro model of human alveolar epithelial differentiation and a potential source of human AT1s.

肺泡上皮I型细胞(AT1s)是远端肺部气体交换屏障的组成部分,一直以来,要分离或在细胞培养中维持这种细胞都很困难。在这里,我们通过诱导多能干细胞(iPSCs)的定向分化,构建了人类体外 AT1 模型系统。我们利用原代成体AT1全局转录组提出了在这些细胞中富集的基准和途径,如Hippo-LATS-YAP/TAZ信号转导。接下来,我们生成了 iPSC 衍生的肺泡上皮 II 型细胞(AT2s),并发现核 YAP 信号足以促进 AT2 基因程序向 AT1 基因程序的广泛转录组转变。由此产生的细胞表现出与人类 AT1 细胞相似的分子、形态和功能表型,包括形成平坦的上皮屏障,产生特征性细胞外基质分子和分泌配体的能力。我们的研究结果提供了人类肺泡上皮分化的体外模型和人类 AT1 的潜在来源。

Traumatic brain injury (TBI) strongly correlates with neurodegenerative disease. However, it remains unclear which neurodegenerative mechanisms are intrinsic to the brain and which strategies most potently mitigate these processes. We developed a high-intensity ultrasound platform to inflict mechanical injury to induced pluripotent stem cell (iPSC)-derived cortical organoids. Mechanically injured organoids elicit classic hallmarks of TBI, including neuronal death, tau phosphorylation, and TDP-43 nuclear egress. We found that deep-layer neurons were particularly vulnerable to injury and that TDP-43 proteinopathy promotes cell death. Injured organoids derived from amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) patients displayed exacerbated TDP-43 dysfunction. Using genome-wide CRISPR interference screening, we identified a mechanosensory channel, KCNJ2, whose inhibition potently mitigated neurodegenerative processes and , including in ALS/FTD organoids. Thus, targeting KCNJ2 may reduce acute neuronal death after brain injury, and we present a scalable, genetically flexible cerebral organoid model that may enable the identification of additional modifiers of mechanical stress.
创伤性脑损伤(TBI)与神经退行性疾病密切相关。然而,目前仍不清楚哪些神经退行性病变机制是大脑固有的,以及哪些策略能最有效地缓解这些过程。我们开发了一种高强度超声平台,用于对诱导多能干细胞(iPSC)衍生的皮质类器官造成机械损伤。受机械损伤的器官组织会引发典型的创伤性脑损伤特征,包括神经元死亡、tau磷酸化和TDP-43核脱落。我们发现深层神经元特别容易受伤,TDP-43蛋白病变会促进细胞死亡。从肌萎缩侧索硬化症/额颞叶痴呆症(ALS/FTD)患者身上提取的损伤器官组织显示出加剧的TDP-43功能障碍。通过全基因组 CRISPR 干扰筛选,我们发现了一种机械感觉通道 KCNJ2,抑制该通道可有效缓解神经退行性过程和 ALS/FTD 器官组织中的 TDP-43 功能障碍。因此,以 KCNJ2 为靶点可能会减少脑损伤后急性神经元的死亡,我们还提出了一种可扩展的、基因灵活的大脑类器官模型,该模型可能有助于鉴定机械应力的其他调节因子。

A simultaneous knockout knockin genome editing strategy in HSPCs potently inhibits CCR5- and CXCR4-tropic HIV-1 infection 在 HSPC 中同时进行基因敲除和基因敲入的基因组编辑策略可有效抑制 CCR5 和 CXCR4-Tropic HIV-1 感染

Allogeneic hematopoietic stem and progenitor cell transplant (HSCT) of null () cells can be curative for HIV-1-infected patients. However, because allogeneic HSCT poses significant risk, matched bone marrow donors are rare, and transplant does not confer resistance to the CXCR4-tropic virus, it is not a viable option for most patients. We describe a targeted Cas9/AAV6-based genome editing strategy for autologous HSCT resulting in both CCR5- and CXCR4-tropic HIV-1 resistance. Edited human hematopoietic stem and progenitor cells (HSPCs) maintain multi-lineage repopulation capacity , and edited primary human T cells potently inhibit infection by both CCR5-tropic and CXCR4-tropic HIV-1. Modification rates facilitated complete loss of CCR5-tropic replication and up to a 2,000-fold decrease in CXCR4-tropic replication without locus disruption. This multi-factor editing strategy in HSPCs could provide a broad approach for autologous HSCT as a functional cure for both CCR5-tropic and CXCR4-tropic HIV-1 infections.
无效()细胞的异基因造血干细胞和祖细胞移植(HSCT)可以治愈HIV-1感染者。然而,由于异基因造血干细胞移植存在巨大风险,匹配的骨髓供体非常罕见,而且移植并不能赋予患者对CXCR4-tropic病毒的抵抗力,因此对于大多数患者来说,这并不是一个可行的选择。我们描述了一种基于 Cas9/AAV6 的自体造血干细胞移植靶向基因组编辑策略,该策略可产生 CCR5 和 CXCR4-Tropic HIV-1 抗性。经过编辑的人类造血干细胞和祖细胞(HSPCs)能保持多系再繁殖能力,而经过编辑的原代人类 T 细胞能有效抑制 CCR5-ropic 和 CXCR4-ropic HIV-1 的感染。在不破坏基因座的情况下,修改率可使 CCR5-Tropic 复制完全消失,CXCR4-tropic 复制减少多达 2000 倍。HSPCs中的这种多因素编辑策略可为自体造血干细胞移植提供一种广泛的方法,作为CCR5-tropic和CXCR4-tropic HIV-1感染的功能性治愈手段。

However, because allogeneic HSCT poses significant risk, matched bone marrow donors are rare, and transplant does not confer resistance to the CXCR4-tropic virus, it is not a viable option for most patients. We describe a targeted Cas9/AAV6-based genome editing strategy for autologous HSCT resulting in both CCR5- and CXCR4-tropic HIV-1 resistance. Edited human hematopoietic stem and progenitor cells (HSPCs) maintain multi-lineage repopulation capacity , and edited primary human T cells potently inhibit infection by both CCR5-tropic and CXCR4-tropic HIV-1. Modification rates facilitated complete loss of CCR5-tropic replication and up to a 2,000-fold decrease in CXCR4-tropic replication without locus disruption. This multi-factor editing strategy in HSPCs could provide a broad approach for autologous HSCT as a functional cure for both CCR5-tropic and CXCR4-tropic HIV-1 infections.","PeriodicalId":9665,"journal":{"name":"Cell stem cell","volume":null,"pages":null},"PeriodicalIF":23.9,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140534643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
