Breast cancer is the most common malignant tumor in women, and the incidence of this disease has increased in recent years because of changes in diet, living environment, gestational age, and other unknown factors. Previous studies focused on cancer cells, but an increasing number of recent studies have analyzed the contribution of cancer microenvironment to the initiation and progression of breast cancer. Cancer-associated fibroblasts (CAFs), the most abundant cells in tumor stroma, secrete various active biomolecules, including extracellular matrix components, growth factors, cytokines, proteases, and hormones. CAFs not only facilitate the initiation, growth, angiogenesis, invasion, and metastasis of cancer but also serve as biomarkers in the clinical diagnosis, therapy, and prognosis of breast cancer. In this article, we reviewed the literature and summarized the research findings on CAFs in breast cancer.

Lung cancer is the most common incident cancer and the leading cause of cancer death. In recent years, the development of tumor immunotherapy especially chimeric antigen receptor T (CAR-T) cell has shown a promising future. Epidermal growth factor receptor variant III (EGFRvIII) is a tumor-specific mutation expressed in various types of tumors and has been detected in non-small cell lung cancer with a mutation rate of 10%. Thus, EGFRvIII is a potential antigen for targeted lung cancer therapy. In this study, CAR vectors were constructed and transfected into virus-packaging cells. Then, activated T cells were infected with retrovirus harvested from stable virus-producing single clone cell lines. CAR expression on the surfaces of the T cells was detected by flow cytometry and Western blot. The function of CAR-T targeting EGFRvIII was then evaluated. The EGFRvIII-CAR vector was successfully constructed and confirmed by DNA sequencing. A stable virus-producing cell line was produced from a single clone by limited dilution. The culture conditions for the cell line, including cell density, temperature, and culture medium were optimized. After infection with retrovirus, CAR was expressed on more than 90% of the T cells. The proliferation of CAR-T cells were induced by cytokine and specific antigen in vitro. More importantly, EGFRvIII-CART specifically and efficiently recognized and killed A549-EGFRvIII cells with an effector/target ratio of 10:1 by expressing and releasing cytokines, including perforin, granzyme B, IFN-g, and TNF-α. The in vivo study indicated that the metastasis of A549-EGFRvIII cells in mice were inhibited by EGFRvIII-CART cells, and the survival of the mice was significantly prolonged with no serious side effects. EGFRvIII-CART showed significantly efficient antitumor activity against lung cancer cells expressing EGFRvIII in vivo and in vitro. Therefore, CAR-T targeting EGFRvIII is a potential therapeutic strategy in preventing recurrence and metastasis of lung cancer after surgery.

由于缺乏经证实具备免疫原性的多肽,基于肿瘤抗原的免疫治疗应用受到限制。在本研究中,利用肝胆肿瘤类器官分析了环状RNA(circRNA)作为肿瘤抗原肽新来源的潜力。使用RNA测序(RNA-seq)和基于算法的评分工具,预测出27 个类器官中3950 个肿瘤特异性circRNA 可翻译18 971 条抗原肽。抗原图谱显示,11 个氨基酸长度(mer)的肽和人类白细胞抗原(HLA)-A结合肽的免疫原性相关评分最高。通过对5 个类器官进行基于质谱的免疫肽组学分析,直接证实其中三个类器官的13 条抗原肽为HLA-A、HLA-B 和HLA-C(HLA-ABC)结合肽。通过流式细胞仪和酶联免疫分析发现,HLA-ABC 呈递的cricRNA来源肿瘤特异性肽可以刺激CD8 T细胞,使其CD107a 和干扰素γ(IFNγ)共表达提高、IFNγ分泌增加。细胞杀伤实验证实,经circRNA 来源免疫原性肽活化的T 细胞可杀伤类器官细胞。值得注意的是,来自circTBC1D15 的抗原肽YGFNEILKK不仅可以被HLA-ABC呈递,还能活化T细胞,显著降低肿瘤类器官活率。本研究的发现提供了一种产生肿瘤抗原的重要来源,提示肿瘤特异性circRNA 可作为抗肿瘤靶点。

Allogeneic hematopoietic stem cell transplantation (HSCT) is one of the most effective options for hematological malignancies, and human leukocyte antigen-partially matched related donors (PMRDs) are a valuable option for HSCT. Several protocols (with or without ex vivo T-cell depletion (TCD)) have been established worldwide. TCD including CD34+positive selection and CD3/CD19 depletion has successfully overcome the human leukocyte antigen disparity. However, TCD is associated with prolonged immune deficiencies, increased risks of infectious complications, and high transplantation-related mortality. PMRD HSCT without ex vivo TCD is well developed, and numerous patients have benefitted from it. Here, we review the literature on PMRD HSCT.

Tumor microenvironment (TME) is comprised of cellular and non-cellular components that exist within and around the tumor mass. The TME is highly dynamic and its importance in different stages of cancer progression has been well recognized. A growing body of evidence suggests that TME also plays pivotal roles in cancer treatment responses. TME is significantly remodeled upon cancer therapies, and such change either enhances the responses or induces drug resistance. Given the importance of TME in tumor progression and therapy resistance, strategies that remodel TME to improve therapeutic responses are under developing. In this review, we provide an overview of the essential components in TME and the remodeling of TME in response to anti-cancer treatments. We also summarize the strategies that aim to enhance therapeutic efficacy by modulating TME.
