Nanomedicine, which includes nanoparticles and other nanomaterials for diagnosis and therapeutic delivery to treat numerous diseases, is making advances [1]. Utilizing engineered nanomaterials as delivery shuttles for therapeutics provides an opportunity to increase targeting specificity for treatments of certain disorders, as well as provide intrinsic benefits to cell systems of interest [2,3]. However, it is important to understand the functional properties of materials in pre-clinical studies. Proper selection of nanomaterials could be enhanced by recent studies in the field of cellular uptake of nanomaterials. The study of EVs is an expanding field within nanomedicine and are one such example of nanomaterials as a drug delivery shuttle. EVs are lipid-bound vesicles ranging in size from 40-1000 nm that mediate intercellular communication through shuttling nucleic acids, protein and lipids between cells.

纳米医学,包括用于诊断和治疗多种疾病的纳米粒子和其他纳米材料,正在取得进展。利用工程纳米材料作为治疗药物的递送载体,为提高某些疾病治疗的靶向特异性提供了机会,同时也为感兴趣的细胞系统提供了内在的好处[2,3]。然而,在临床前研究中,了解材料的功能特性是很重要的。最近在纳米材料的细胞摄取领域的研究可以提高纳米材料的正确选择。电动汽车的研究是纳米医学中一个不断发展的领域,是纳米材料作为药物传递穿梭体的一个例子。EVs是脂质结合囊泡,大小在40-1000 nm之间,通过在细胞间穿梭核酸、蛋白质和脂质介导细胞间通讯。曾经被认为是细胞的分泌废物,由于其遗传材料的生物相容性、治疗潜力、低免疫原性和毒性、跨越生物屏障的能力以及重复给药和多种给药途径等多重内在优势,ev已被设计为药物递送载体[4-6]。我们小组和其他人之前的工作表明,治疗潜力和摘要

Anti-PD1 Therapy in Lynch Syndrome-associated Recurrent Glioblastoma 抗pd1治疗Lynch综合征相关复发性胶质母细胞瘤

Less than 5% of glioblastomas result from a hereditary syndrome. While not common, they do occur and perhaps may be under-recognized if family history is not known. Now, with more frequent germline testing done as a component of next generation tumor sequencing, it is hypothesized that these hereditary syndromes are better detected. This improved detection is not only beneficial for screening family members and screening the patient for other associated malignancies, but this opens up an opportunity for us as clinicians and scientists to better understand the tumorigenesis of glioblastoma in hereditary syndromes, which in turn may offer individualized treatment regimens.
不到5%的胶质母细胞瘤是由遗传综合征引起的。虽然不常见,但确实会发生,如果不了解家族史,可能会被低估。现在,随着更频繁的生殖系检测作为下一代肿瘤测序的组成部分,假设这些遗传综合征可以更好地检测到。这种改进的检测不仅有利于筛查家庭成员和筛查患者的其他相关恶性肿瘤,而且这为我们作为临床医生和科学家更好地了解遗传综合征中胶质母细胞瘤的肿瘤发生提供了机会,从而可以提供个性化的治疗方案。

Profiling the Energy Metabolism at the Cell Subpopulation Level 在细胞亚群水平上分析能量代谢
Pub Date : 2021-11-05 DOI: 10.33696/cancerimmunol.3.050
K. Benihoud, C. Brenner
Although being a complex pathology with genetic as well as non-genetic etiologies, cancer is characterized by a limited series of hallmarks including energetic metabolism reprogramming [1]. Long ago O. Warburg unraveled a bias of tumor metabolism in favor of glycolysis, the socalled Warburg effect. Indeed, tumor cells display both an increase in glucose uptake and fermentation of glucose to lactate [2]. Since these pioneering works, different alterations of tumor metabolism were reported such as deregulated uptake of glutamine or new modes of nutrient acquisition [3]. In general, cancer cells exhibit a high rate of proliferation due to constitutive anabolism and catabolism activation. Moreover, by competing for nutrients, inducing hypoxia and releasing inhibitory molecules in tumor microenvironment (TME), tumors dramatically affect immune cell metabolism [4].
尽管癌症是一种复杂的病理学,既有遗传病因,也有非遗传病因,但其特征是一系列有限的特征,包括能量代谢重编程[1]。很久以前,O.Warburg发现肿瘤代谢偏向于糖酵解,即所谓的Warburg效应。事实上,肿瘤细胞表现出葡萄糖摄取增加和葡萄糖发酵为乳酸[2]。自从这些开创性的工作以来,报道了肿瘤代谢的不同变化,如谷氨酰胺的摄取失调或营养获取的新模式[3]。一般来说,由于组成性合成代谢和分解代谢激活,癌症细胞表现出高增殖率。此外,通过在肿瘤微环境(TME)中竞争营养、诱导缺氧和释放抑制分子,肿瘤显著影响免疫细胞代谢[4]。

Polycyclic Aromatic Hydrocarbons and Mammary Cancer Risk: Does Obesity Matter too? 多环芳烃与乳腺癌风险:肥胖也有关系吗?
Pub Date : 2021-10-27 DOI: 10.33696/cancerimmunol.3.052

Breast cancer risk remains incompletely explained, and higher incidence rates of breast cancer over recent times and in urban and industrialized areas suggest environmental causes. Polycyclic aromatic hydrocarbons (PAH) are ubiquitous in the environment and epidemiological and rodent studies have shown associations between exposure to PAH and breast cancer incidence as well as mammary tumorigenesis. In addition, in vitro and rodent studies have implicated alterations in estrogen receptor alpha (Erα) signaling pathways following PAH exposure in limited experimental studies. However, our understanding of these mechanisms is incomplete. Sahay et al. addressed this gap by examining the effect of PAH exposure on epigenetic and transcriptional regulation of genes in the Erα pathway in a mouse cohort exposed to aerosolized PAH at proportions measured in urban air. In addition to alterations in the Erα signaling pathway in the pregnant mice and in their offspring and grandoffspring, the investigators observed higher body weights in mice exposed to PAH compared to the control. Given that associations between mammary tissue adiposity, systemic adiposity, and breast cancer risk have been observed previously, the finding of higher body weight in the PAH exposure group raises the possibility that body weight might influence the association between PAH exposure and breast cancer risk. Along with new analyses, we discuss the possibility that body weight may modify the association between PAH exposure, mammary cellular proliferation, and mammary gland ductal hyperplasia in offspring and grandoffspring mice and future research that may be needed to delineate these associations.
乳腺癌症的风险仍然没有得到完全解释,近年来以及城市和工业化地区癌症的发病率较高表明是环境原因。多环芳烃(PAH)在环境中普遍存在,流行病学和啮齿类动物研究表明,接触PAH与乳腺癌症发病率以及乳腺肿瘤发生之间存在关联。此外,在有限的实验研究中,体外和啮齿类动物研究表明,PAH暴露后雌激素受体α(Erα)信号通路发生了变化。然而,我们对这些机制的理解是不完整的。Sahay等人通过研究PAH暴露对暴露于城市空气中测量比例的雾化PAH的小鼠队列中Erα通路基因的表观遗传学和转录调控的影响,解决了这一差距。除了怀孕小鼠及其后代和孙子女的Erα信号通路发生变化外,研究人员还观察到,与对照组相比,暴露于PAH的小鼠体重更高。鉴于先前已观察到乳腺组织肥胖、全身性肥胖和乳腺癌症风险之间的相关性,PAH暴露组中较高体重的发现增加了体重可能影响PAH暴露与乳腺癌症风险之间的关联的可能性。除了新的分析外,我们还讨论了体重可能改变后代和孙代小鼠PAH暴露、乳腺细胞增殖和乳腺导管增生之间关系的可能性,以及未来可能需要的研究来描述这些关系。

Emerging Roles of Pseudogene RNAs in Antitumor and Antiviral Immunity 假基因RNA在抗肿瘤和抗病毒免疫中的新作用
Pub Date : 2021-06-30 DOI: 10.33696/cancerimmunol.3.045

Tumor immunity and immunotherapy have become increasingly important in treatment strategies for a variety of malignancies including advanced triple negative breast cancer [1,2]. Although immunotherapy has been shown to be effective, patient response rates vary significantly and only a small fraction of patients respond favorably to the treatment [3]. The efficacy of cancer immunotherapy appears to depend on the host immune system recognizing and eliminating cancer cells [4]. Increasing evidence demonstrates a positive correlation between the presence of host antitumor immune responses and favorable patient outcomes for many cancers [5-8]. As an example, tumors with a high density of tumor-infiltrating lymphoid cells (TILs) in the tumor microenvironment are more likely to respond to immune checkpoint inhibitors, whereas those with low or no TILs are less likely to respond to the inhibitors [9-11]. Thus, interventions that render nonresponding tumors to become responding tumors and hence promote antitumor immunity bear tremendous therapeutic potential.
肿瘤免疫和免疫疗法在各种恶性肿瘤的治疗策略中变得越来越重要,包括晚期癌症三阴性[1,2]。尽管免疫疗法已被证明是有效的,但患者的反应率差异很大,只有一小部分患者对治疗有良好反应[3]。癌症免疫疗法的疗效似乎取决于宿主免疫系统识别和消除癌症细胞[4]。越来越多的证据表明,宿主抗肿瘤免疫反应的存在与许多癌症的良好患者预后之间存在正相关[5-8]。例如,肿瘤微环境中肿瘤浸润性淋巴细胞(TIL)密度高的肿瘤更有可能对免疫检查点抑制剂产生反应,而TIL低或无TIL的肿瘤则不太可能对抑制剂产生反应[9-11]。因此,将无反应的肿瘤转化为有反应的肿瘤,从而促进抗肿瘤免疫的干预措施具有巨大的治疗潜力。

Increasing evidence demonstrates a positive correlation between the presence of host antitumor immune responses and favorable patient outcomes for many cancers [5-8]. As an example, tumors with a high density of tumor-infiltrating lymphoid cells (TILs) in the tumor microenvironment are more likely to respond to immune checkpoint inhibitors, whereas those with low or no TILs are less likely to respond to the inhibitors [9-11]. Thus, interventions that render nonresponding tumors to become responding tumors and hence promote antitumor immunity bear tremendous therapeutic potential.","PeriodicalId":73633,"journal":{"name":"Journal of cancer immunology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41779899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
