Abstract
The pericardium plays several homeostatic roles to support and maintain everyday cardiac function. Recent advances in techniques and experimental models have allowed for further exploration into the cellular contents of the pericardium itself. Of particular interest are the various immune cell populations present in the space within the pericardial fluid and fat. In contrast to immune cells of the comparable pleura, peritoneum and heart, pericardial immune cells appear to be distinct in their function and phenotype. Specifically, recent work has suggested these cells play critical roles in an array of pathophysiological conditions including myocardial infarction, pericarditis, and post-cardiac surgery complications. In this review, we spotlight the pericardial immune cells currently identified in mice and humans, the pathophysiological role of these cells, and the clinical significance of the immunocardiology axis in cardiovascular health.

Adoptive T-cell immunotherapy in digestive tract malignancies: Current challenges and future perspectives. Cancer Treat Rev 2021; 100:102288. [PMID: 34525422 DOI: 10.1016/j.ctrv.2021.102288] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/31/2021] [Accepted: 09/02/2021] [Indexed: 12/15/2022]
Abstract
Multiple systemic treatments are currently available for advanced cancers of the digestive tract, but none of them is curative. Adoptive T-cell immunotherapy refers to the extraction, modification and re-infusion of autologous or allogenic T lymphocytes for therapeutic purposes. A number of clinical trials have investigated either non-engineered T cells (i.e., lymphokine-activated killer cells, cytokine induced killer cells, or tumor-infiltrating lymphocytes) or engineered T cells (T cell receptor-redirected T cells or chimeric antigen receptor T cells) in patients with digestive tract malignancies over the past two decades, with variable degrees of success. While the majority of completed trials have been primarily aimed at assessing the safety of T-cell transfer strategies, a new generation of studies is being designed to formally evaluate the antitumor potential of adoptive T-cell immunotherapy in both the metastatic and adjuvant settings. In this review, we provide an overview of completed and ongoing clinical trials of passive T-cell immunotherapy in patients with cancers of the digestive tract, focusing on present obstacles and future strategies for achieving potential success.

Pharmaceuticals (Basel) 2021; 14:656. [PMID: 34358082 PMCID: PMC8308499 DOI: 10.3390/ph14070656] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 07/01/2021] [Accepted: 07/07/2021] [Indexed: 02/07/2023] Open
Abstract
Hepatocellular carcinoma (HCC) has emerged as one of the most lethal cancers worldwide because of its high refractoriness and multi-drug resistance to existing chemotherapies, which leads to poor patient survival. Novel pharmacological strategies to tackle HCC are based on oral multi-kinase inhibitors like sorafenib; however, the clinical use of the drug is restricted due to the limited survival rate and significant side effects, suggesting the existence of a primary or/and acquired drug-resistance mechanism. Because of this hurdle, HCC patients are forced through incomplete therapy. Although multiple approaches have been employed in parallel to overcome multidrug resistance (MDR), the results are varying with insignificant outcomes. In the past decade, cancer immunotherapy has emerged as a breakthrough approach and has played a critical role in HCC treatment. The liver is the main immune organ of the lymphatic system. Researchers utilize immunotherapy because immune evasion is considered a major reason for rapid HCC progression. Moreover, the immune response can be augmented and sustained, thus preventing cancer relapse over the post-treatment period. In this review, we provide detailed insights into the immunotherapeutic approaches to combat MDR by focusing on HCC, together with challenges in clinical translation.

Abstract
At present, there is no accurate and effective method for treating neoplastic pericardial effusion. This study analyzed the current literature on the treatment of neoplastic pericardial effusion to provide advice and guidance for clinical treatment. Surgical treatments include pericardial puncture, extension of catheter drainage, pericardial window, and surgical pericardiotomy. Each surgical procedure has a corresponding indication, and the best treatment is selected according to the patient's specific conditions. Systemic chemotherapy is effective in lymphoma and small cell lung cancer that are sensitive to chemotherapeutic drugs. Although pericardial injection of drugs is effective for pericardial tamponade and recurrent pericardial effusion, these methods can only temporarily relieve symptoms and cannot prolong the life of patients. In recent years, immunotherapy, especially adoptive immunotherapy, has achieved good results in the treatment of neoplastic pericardial effusion, thus providing a novel treatment option for neoplastic pericardial effusion.

Abstract
Primary liver cancer is a common kind of digestive cancers with high malignancy, causing 745,500 deaths each year. Hepatocellular carcinoma is the major pathological type of primary liver cancer. Traditional treatment methods for patients with hepatocellular carcinoma have shown poor efficacy in killing residual cancer cells for a long time. In recent years, tumor immunotherapy has emerged as a promising method owing to its safety and efficacy with respect to delaying the progression of advanced tumors and protecting postoperative patients against tumor relapse and metastasis. Immune tolerance and suppression in tumor microenvironments are the theoretical basis of immunotherapy. Adoptive cell therapy functions by stimulating and cultivating autologous lymphocytes ex vivo and then reinfusing them into the patient to kill cancer cells. Cancer vaccination is performed using antigenic substances to activate tumor-specific immune responses. Immune checkpoint inhibitors can reactivate tumor-specific T cells and develop an antitumor effect by suppressing checkpoint-mediated signaling. Oncolytic viruses may selectively replicate in tumor cells and cause lysis without harming normal tissues. Here, we briefly introduce the mechanism of immunosuppression in hepatocellular carcinoma and summarize the rationale of the four major immunotherapeutic approaches with their current advances.

Abstract
Objective Combination therapy for cancer is more effective than using only standard chemo- or radiotherapy. Our previous results showed that dendritic cell-activated α-fetoprotein (AFP)-specific T-cells inhibit tumor in vitro and in vivo. In this study, we focused on antitumor function of CD8+ T-cells combined with or without JAK2 inhibitor. Methods Proliferation and cell cycle were analyzed by CCK-8 and flow cytometry. Western blot was used to analyze the expression level of related protein and signaling pathway. Results We demonstrated reduced viability and induction of apoptosis of tumor cells with combination treatment. Intriguingly, cell cycle was blocked at the G1 phase by using AFP-specific CD8+ T-cells combined with JAK2 inhibitor (AG490). Furthermore, an enhanced expression of BAX but no influence on Fas/FasL was detected from the tumor cells. Conclusion These results indicate a Fas/FasL-independent pathway for cellular apoptosis in cancer therapies with the treatment of AFP-specific CD8+ T-cells combined with JAK2 inhibitor.

Combined IFN-gamma-endostatin gene therapy and radiotherapy attenuates primary breast tumor growth and lung metastases via enhanced CTL and NK cell activation and attenuated tumor angiogenesis in a murine model. Ann Surg Oncol 2009; 16:1403-11. [PMID: 19263173 DOI: 10.1245/s10434-009-0343-6] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2008] [Revised: 10/31/2008] [Accepted: 01/09/2009] [Indexed: 12/26/2022]
Abstract
BACKGROUND Gene-radiotherapy, a combination of gene therapy and radiotherapy, is a new paradigm for cancer treatment, with the potential to simultaneously improve local and systemic breast cancer control. The aim of this study was to evaluate antitumor effect of interferon (IFN)-gamma-endostatin-based gene-radiotherapy in a murine metastatic breast tumor model, and to elucidate possible mechanisms involved. METHODS Murine mammary adenocarcinoma 4T1 cells transfected with pEgr-IFN-gamma and pEgr-endostatin plasmids were irradiated (2-20 Gy). IFN-gamma and endostatin levels in the culture supernatants were measured. In vivo female BALB/c mice were inoculated with 1 x 10(5) 4T1 cells by mammary fat pad injection and divided into control, empty vector, gene therapy (pEgr-IFN-gamma and pEgr-endostatin), radiotherapy, and combined gene-radiotherapy groups. Tumor growth, tumor/body weight ratio, lung metastases, and survival of the tumor-bearing mice were observed. Splenic cytotoxic T-lymphocyte (CTL) and natural killer (NK) cell activity and intratumor microvessel density were also assessed. RESULTS Irradiation significantly enhanced IFN-gamma and endostatin secretion from the transfected 4T1 cells. In vivo mice that received combined gene-radiotherapy showed maximal attenuation in tumor growth rate and lung metastases with increased survival compared with mice that received gene therapy or radiotherapy alone. This was associated with significantly enhanced CTL and NK cell activity and reduced intratumor microvessel density. CONCLUSION These results demonstrate that IFN-gamma-endostatin-based gene-radiotherapy provide a potent antitumor effect in a murine metastatic breast tumor model, which may relate to IFN-gamma-stimulated CTL and NK cell activation, and endostatin-induced antiangiogenic activity. Thus, gene-radiotherapy may represent a useful addition to neoadjuvant management of locally advanced breast cancer.
