T-cell lymphomas represent a subpopulation of non-Hodgkin lymphomas with poor outcomes when treated with conventional chemotherapy. A variety of novel agents have been introduced as new treatment strategies either as first-line treatment or in conjunction with chemotherapy. Immunotherapy has been demonstrated to be a promising area for new therapeutics, including monoclonal antibodies and adoptive cellular therapeutics. T-cell therapeutics have been shown to have significant success in the treatment of B-cell malignancies and are rapidly expanding as potential treatment options for other cancers including T-cell lymphomas. Although treating T-cell lymphomas with T-cell therapeutics has unique challenges, multiple targets are currently being studied both preclinically and in clinical trials. 相似文献

Adoptive cell therapy of tumor-infiltrating lymphocytes has shown promise for treatment of refractory melanoma and other solid malignancies; however, challenges to manufacturing have limited its widespread use. Traditional manufacturing efforts were lengthy, cumbersome and used open culture systems. We describe changes in testing and manufacturing that decreased the process cycle time, enhanced the robustness of critical quality attribute testing and facilitated a functionally closed system. These changes have enabled export of the manufacturing process to support multi-center clinical trials. 相似文献

In February 2018, the Melanoma Research Foundation and the Moffitt Cancer Center hosted the Second Summit on Melanoma Central Nervous System (CNS) Metastases in Tampa, Florida. In this white paper, we outline the current status of basic science, translational, and clinical research into melanoma brain metastasis development and therapeutic management. We further outline the important challenges that remain for the field and the critical barriers that need to be overcome for continued progress to be made in this clinically difficult area. 相似文献

Tissue‐resident memory T (TRM) cells are abundant in the memory T cell pool and remain resident in peripheral tissues, such as the skin, where they act as alarm sensors or cytotoxic killers. TRM cells persist long after the pathogen is eliminated and can respond rapidly upon reinfection with the same antigen. When aberrantly activated, skin‐located TRM cells have a profound role in various skin disorders, including vitiligo and melanoma. Autoreactive TRM cells are present in human lesional vitiligo skin and mouse models of vitiligo, which suggests that targeting these cells could be effective as a durable treatment strategy for vitiligo. Furthermore, emerging evidence indicates that induction of melanoma‐reactive TRM cells is needed to achieve effective protection against tumor growth. This review highlights seminal reports about skin‐resident T cells, focusing mainly on their role in the context of vitiligo and melanoma, as well as their potential as therapeutic targets in both diseases. 相似文献

肿瘤是21世纪威胁人类健康的主要疾患之一。临床上,实体瘤治疗仍以手术切除、放化疗和靶向治疗为主,但这些方法往往不能根除肿瘤病灶,易导致肿瘤复发和进展。肿瘤免疫治疗是利用人体的免疫系统,通过增强或恢复抗肿瘤免疫力实现控制和杀伤肿瘤的一种新的治疗模式。肿瘤免疫治疗能够在众多患者中产生持久反应,过继性免疫治疗和免疫检查点阻断剂治疗均可产生显著的抗原特异性免疫反应。肿瘤浸润淋巴细胞(TILs)是一种存在于肿瘤组织内部具有高度异质性的淋巴细胞,在宿主抗原特异性肿瘤免疫应答中发挥关键作用。最新研究表明,在肿瘤发生和治疗过程中,TILs的亚群组成和数量与患者预后密切相关;抗肿瘤的TILs介导的过继性免疫治疗方法已在多种实体瘤中取得了良好的疗效。文中就实体肿瘤中TILs的研究进展作一综述。 相似文献

以线性表位肽P14(a3127-148)作为抗原建立适合免疫治疗的抗肾小球基底膜(anti-glomerular basement membrane,GBM)病大鼠模型。采用大鼠后脚垫三点注射P14(a3127-148)与弗氏佐剂乳化物的方法进行单次免疫,免疫前后每周采集24 h尿样和血样,所有大鼠在免疫后7 w处死。大鼠免疫后,肾炎模型组在各时间点的24 h尿蛋白、尿蛋白肌酐比值(albumin/urine creatinine ratio,ACR)、血肌酐及血尿素氮均明显高于对照组(P<0.05);循环抗P14(a3127-148)IgG抗体水平明显高于对照组(P<0.001);PAS染色可见节段性纤维素样坏死,富于细胞型新月体;免疫组化染色可见肾小球有明显的中性粒细胞和巨噬细胞浸润;免疫荧光检测可见IgG沿GBM呈强线性沉积;电镜观察到GBM的断裂和收缩;而对照组均未见改变。HE染色在所有大鼠中均未观察到肺部病变。使用P14(a3127-148)线性肽免疫WKY大鼠成功建立了大鼠抗GBM病模型,有助于开发更为特异的免疫疗法。 相似文献

溶瘤病毒(oncolytic virus,OVs)历经百年发展,应用于当前最具潜力的肿瘤免疫疗法。它主要是天然的或基因修饰的DNA病毒和RNA病毒。近年来随着基因工程技术的飞跃发展,经基因改造的溶瘤病毒在肿瘤治疗领域取得很大进展,很多不同类型的病毒(包括单纯疱疹病毒、腺病毒、痘病毒、麻疹病毒和呼肠孤病毒等)正处于临床前研究、临床试验阶段或已批准上市,显示了良好的安全性和临床疗效。普遍认为溶瘤病毒靶向杀伤肿瘤细胞是通过选择性在肿瘤细胞内自我复制,最终裂解肿瘤细胞,同时可激发机体的免疫应答反应,进而增强抗肿瘤免疫效果,靶向杀伤肿瘤细胞而对正常细胞无明显影响。运用基因重组技术将溶瘤病毒与免疫检查点相结合以及肿瘤免疫联合疗法的兴起和不断进步,使溶瘤病毒的应用更加广泛,但仍存在病毒靶向性、安全性、给药途径等瓶颈问题。本文综述了溶瘤病毒的发展史、病毒分类、不同类型溶瘤病毒产品的临床研究进展、溶瘤病毒靶向杀伤肿瘤的免疫学机制及未来发展面临的挑战与展望等。 相似文献

Cyclooxygenase-2 is a very important physiological enzyme playing key roles in various biological functions especially in the mechanism of pain and inflammation, among other roles, making it a molecule of high interest to the pharmaceutical community as a target. COX 2 enzyme is induced only during inflammatory processes or cancer and reflects no role in the guarding stomach lining. Thus, selective COX-2 inhibition can significantly reduce the adverse effects including GI tract damage and hepatotoxic effects of traditional NSAIDs like aspirin, ibuprofen, etc. Recent developments on COX-2 inhibitors is primarily focused on improving the selectivity index of the drug towards COX-2 along with enhancing the potency of the drug by modifying the scaffolds of Coxibs currently in the market like Celecoxib, Indomethacin, Oxaprozin, etc. We have reported the progress on new COX-2 inhibitors in the last decade (2008–2019) focussing on five heterocyclic rings- Pyrazole, Indole, Oxazole, Pyridine and Pyrrole. The addition of various moieties to these core rings and their structure-activity relationship along with their molecular modelling data have been explored in the article. This review aims to aid medicinal chemists in the design and discovery of better COX-2 inhibitors constructed on these five heterocyclic pharmacophores. 相似文献
