Imai Y. Novel treatment strategies for hematological malignancies in the immunotherapy era. Int J Hematol 2024:10.1007/s12185-024-03793-1. [PMID: 38861242 DOI: 10.1007/s12185-024-03793-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 05/02/2024] [Accepted: 05/16/2024] [Indexed: 06/12/2024]
Abstract
The introduction of immunotherapies has led to remarkable progress in the treatment of hematological malignancies, including B-cell malignancies such as B-cell lymphoma and multiple myeloma (MM). Although conventional therapeutic antibodies are effective as immunotherapy for newly diagnosed and relapsed/refractory B-cell lymphoma and MM, some cases are resistant. Chimeric antigen receptor (CAR) T-cell therapies targeting B-cell lymphoma and MM have progressed through several generations, and have improved treatment strategies for relapsed/refractory disease. In addition to conventional therapeutic antibodies, bispecific antibodies targeting both tumor cells and T cells have been developed for MM. Both CAR T-cell therapies and bispecific antibodies are effective for heavily treated patients with relapsed/refractory disease. However, most patients treated with these therapies relapse, and serious adverse events like cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) are problematic. This Progress in Hematology, "Novel treatment strategies for hematological malignancies in the immunotherapy era," focuses on such limitations and the future outlook for CAR T-cell therapies and bispecific antibodies for B-cell malignancies. The role of NK cells in anti-tumor immunity for AML and various therapeutic strategies for NK-cell therapy in AML is also discussed.

Clinical Significance of Nectins in HCC and Other Solid Malignant Tumors: Implications for Prognosis and New Treatment Opportunities-A Systematic Review. Cancers (Basel) 2023; 15:3983. [PMID: 37568798 PMCID: PMC10416819 DOI: 10.3390/cancers15153983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 07/17/2023] [Accepted: 07/21/2023] [Indexed: 08/13/2023] Open
Abstract
The nectin family comprises four proteins, nectin-1 to -4, which act as cell adhesion molecules. Nectins have various regulatory functions in the immune system and can be upregulated or decreased in different tumors. The literature research was conducted manually by the authors using the PubMed database by searching articles published before 2023 with the combination of several nectin-related keywords. A total of 43 studies were included in the main section of the review. Nectins-1-3 have different expressions in tumors. Both the loss of expression and overexpression could be negative prognostic factors. Nectin-4 is the best characterized and the most consistently overexpressed in various tumors, which generally correlates with a worse prognosis. New treatments based on targeting nectin-4 are currently being developed. Enfortumab vedotin is a potent antibody-drug conjugate approved for use in therapy against urothelial carcinoma. Few reports focus on hepatocellular carcinoma, which leaves room for further studies comparing the utility of nectins with commonly used markers.

Risk Stratification for Breast Cancer Patient by Simultaneous Learning of Molecular Subtype and Survival Outcome Using Genetic Algorithm-Based Gene Set Selection. Cancers (Basel) 2022; 14:cancers14174120. [PMID: 36077657 PMCID: PMC9454699 DOI: 10.3390/cancers14174120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 08/18/2022] [Accepted: 08/20/2022] [Indexed: 11/26/2022] Open
Abstract
Simple Summary Patient stratification is clinically important because it allows us to understand the characteristics and establish treatment strategies for a group. Transcriptomic data play an important role in determining molecular subtypes and predicting survival. In the case of breast cancer, although the order of prognosis according to molecular subtypes is well known, there is heterogeneity even within a subtype. Therefore, patient stratification considering both molecular subtypes and survival outcomes is required. In this study, a methodology to handle this problem is presented. A genetic algorithm is used to select a set of genes, and a risk score is assigned to each patient using their expression level. According to the risk score, patients are ordered and stratified considering molecular subtypes and survival outcomes. Consequently, informative genes for patient stratification with respect to both aspects could be nominated, and the usefulness of the risk score was shown through comparison with other indicators. Abstract Patient stratification is a clinically important task because it allows us to establish and develop efficient treatment strategies for particular groups of patients. Molecular subtypes have been successfully defined using transcriptomic profiles, and they are used effectively in clinical practice, e.g., PAM50 subtypes of breast cancer. Survival prediction contributed to understanding diseases and also identifying genes related to prognosis. It is desirable to stratify patients considering these two aspects simultaneously. However, there are no methods for patient stratification that consider molecular subtypes and survival outcomes at once. Here, we propose a methodology to deal with the problem. A genetic algorithm is used to select a gene set from transcriptome data, and their expression quantities are utilized to assign a risk score to each patient. The patients are ordered and stratified according to the score. A gene set was selected by our method on a breast cancer cohort (TCGA-BRCA), and we examined its clinical utility using an independent cohort (SCAN-B). In this experiment, our method was successful in stratifying patients with respect to both molecular subtype and survival outcome. We demonstrated that the orders of patients were consistent across repeated experiments, and prognostic genes were successfully nominated. Additionally, it was observed that the risk score can be used to evaluate the molecular aggressiveness of individual patients.

Abstract
In recent years, a set of immune receptors that interact with members of the nectin/nectin-like (necl) family has garnered significant attention as possible points of manipulation in cancer. Central to this axis, CD226, TIGIT, and CD96 represent ligand (CD155)-competitive co-stimulatory/inhibitory receptors, analogous to the CTLA-4/B7/CD28 tripartite. The identification of PVRIG (CD112R) and CD112 has introduced complexity and enabled additional nodes of therapeutic intervention. By virtue of the clinical progression of TIGIT antagonists and emergence of novel CD96- and PVRIG-based approaches, our overall understanding of the ‘CD226 axis’ in cancer immunotherapy is starting to take shape. However, several questions remain regarding the unique characteristics of, and mechanistic interplay between, each receptor-ligand pair. This review provides an overview of the CD226 axis in the context of cancer, with a focus on the status of immunotherapeutic strategies (TIGIT, CD96, and PVRIG) and their underlying biology (i.e., cis/trans interactions). We also integrate our emerging knowledge of the immune populations involved, key considerations for Fc gamma (γ) receptor biology in therapeutic activity, and a snapshot of the rapidly evolving clinical landscape.

Abstract
The recent discovery of immune checkpoint inhibitors is a significant milestone in cancer immunotherapy research. However, some patients with primary or adaptive drug resistance might not benefit from the overall therapeutic potential of immunotherapy in oncology. Thus, it is becoming increasingly critical for oncologists to explore the availability of new immune checkpoint inhibitors. An emerging co-inhibitory receptor, CD112R (also called PVRIG), is most commonly expressed on natural killer (NK) and T cells. It binds to its ligand (CD112 or PVRL2/nectin-2) and inhibits the strength with which T cells and NK cells respond to cancer. Therefore, CD112R is being presented as a new immune checkpoint inhibitor with high potential in cancer immunotherapy. CD112 is easily detectable on antigen-presenting or tumor cells, and its high level of expression has been linked with tumor progression and poor outcomes in most cancer patients. This review explores the molecular and functional relationship between CD112R, TIGIT, CD96, and CD226 in T cell responses. In addition, this review comprehensively discusses the recent developments of CD112R/CD112 immune checkpoints in cancer immunotherapy and prognosis.

Abstract
It is increasingly clear that the nectin family and its immunoreceptors shape the immune response to cancer through several pathways. Yet, even as antibodies against TIGIT, CD96, and CD112R advance into clinical development, biological and therapeutic questions remain unanswered. Here, we review recent progress, prospects, and challenges to understanding and tapping this family in cancer immunotherapy.

Abstract
CD226, a member of the immunoglobulin superfamily, is a functional protein initially expressed on natural killer and T cells. In recent years, the function of CD226 has been increasingly realized and researched. Accumulating evidence shows that CD226 is closely related to the occurrence of autoimmune diseases, infectious diseases, and tumors. Because of the CD226’s increasing importance, the author herein discusses the structure, mechanism of action, and role of CD226 in various pathophysiological environments, allowing for further understanding of the function of CD226 and providing the basis for further research in related diseases.

Abstract
Sarcomas are malignancies of mesenchymal origin that occur in bone and soft tissues. Many are chemo- and radiotherapy resistant, thus conventional treatments fail to increase overall survival. Natural Killer (NK) cells exert anti-tumor activity upon detection of a complex array of tumor ligands, but this has not been thoroughly explored in the context of sarcoma immunotherapy. In this study, we investigated the NK cell receptor/ligand immune profile of primary human sarcoma explants. Analysis of tumors from 32 sarcoma patients identified the proliferative marker PCNA and DNAM-1 ligands CD112 and/or CD155 as commonly expressed antigens that could be efficiently targeted by genetically modified (GM) NK cells. Despite the strong expression of CD112 and CD155 on sarcoma cells, characterization of freshly dissociated sarcomas revealed a general decrease in tumor-infiltrating NK cells compared to the periphery, suggesting a defect in the endogenous NK cell response. We also applied a functional screening approach to identify relevant NK cell receptor/ligand interactions that induce efficient anti-tumor responses using a panel NK-92 cell lines GM to over-express 12 different activating receptors. Using GM NK-92 cells against primary sarcoma explants (n = 12) revealed that DNAM-1 over-expression on NK-92 cells led to efficient degranulation against all tested explants (n = 12). Additionally, NKG2D over-expression showed enhanced responses against 10 out of 12 explants. These results show that DNAM-1+ or NKG2D+ GM NK-92 cells may be an efficient approach in targeting sarcomas. The degranulation capacity of GM NK-92 cell lines was also tested against various established tumor cell lines, including neuroblastoma, Schwannoma, melanoma, myeloma, leukemia, prostate, pancreatic, colon, and lung cancer. Enhanced degranulation of DNAM-1+ or NKG2D+ GM NK-92 cells was observed against the majority of tumor cell lines tested. In conclusion, DNAM-1 or NKG2D over-expression elicited a dynamic increase in NK cell degranulation against all sarcoma explants and cancer cell lines tested, including those that failed to induce a notable response in WT NK-92 cells. These results support the broad therapeutic potential of DNAM-1+ or NKG2D+ GM NK-92 cells and GM human NK cells for the treatment of sarcomas and other malignancies.

Abstract
Nectin-2 is overexpressed in cancer cells and is associated with poor prognosis in patients with various types of cancers. However, its involvement in esophageal squamous cell carcinoma (ESCC) remains unknown. The present study aimed to investigate the expression pattern of Nectin-2, its clinical significance and its roles in the malignant phenotypes of ESCC. Expression levels of Nectin-2 mRNA and protein were respectively detected by reverse transcription-quantitative polymerase chain reaction, western blotting and immunohistochemistry, based on 106 newly diagnosed ESCC patients. The associations between Nectin-2 expression and clinicopathological characteristics of ESCC patients were statistically analyzed. The effects of Nectin-2 in migration and invasion were then determined by wound healing and Transwell assays performed using ESCC cell lines (ECA109 and KYSE510) transfected with small interfering (si) RNA against Nectin-2. It was found that Nectin-2 expression was significantly elevated at the mRNA and protein levels in ESCC tissues, compared with the normal esophageal mucosa (P<0.001). Nectin-2-positive immunoreactivity was mainly localized in the cytoplasm of cancer cells in ESCC tissues. In addition, the expression levels of Nectin-2 protein in ESCC tissues with advanced tumor stage (P=0.006) and poor differentiation (P=0.02) were increased compared with patients with early tumor stage and well to moderate differentiation. Additionally, knockdown of Nectin-2 in the 2 ESCC cell lines could effectively suppress the cell migration and invasion abilities (P<0.05). In conclusion, these findings revealed that Nectin-2 is generally overexpressed in ESCC and associated with aggressive cancer progression. The present data also indicated that the silencing of Nectin-2 with siRNA in ESCC cells may inhibit cell malignant biological properties, indicating its potential as a potential marker or a therapeutic target for ESCC.

Abstract
Our study is aim to investigate the influence of miR-892a on proliferative and invasive activities of human hepatocellular carcinoma (HCC) cells through regulating CD226 expression. QRT-PCR was used to detect the expression levels of miR-892a and CD226 mRNA in HCC tissues and adjacent tissues or HCC cells and normal cells whereas Western Blot was used to detect the CD226 protein expression in tissue and cell samples. Then HuH-7 cell line was selected for following assays and respectively transfected with miR-892a mimics, miR-NC, Plenti-GIII-Ubc-CD226, and Plenti-GIII-Ubc followed by qRT-PCR assay to detect the miR-892a and CD226 expression. The luciferase reporter assay was conducted to determine if miR-892a directly targeted CD226 and then CCK-8 assay, wound healing assay, Transwell assay, and flow cytometry were used to detect cell proliferation, migration, invasion ability, cell cycle, and cell apoptosis. What's more, relationships between expression levels of miR-892a or CD226 and overall survival (OS) or disease-free survival (DFS) of HCC patients were investigated based on TCGA database. MiR-892a was high-expressed in HCC tissues or cells while CD226 was low-expressed. MiR-892a directly targeted CD226 and up-regulating miR-892a expression could promote proliferative, migrating, and invasive activities of HCC cells. Different expression levels of miR-892a and CD226 both related to the prognosis of HCC. MiR-892a promotes hepatocellular carcinoma cells proliferation and invasion through regulating CD226 expression. J. Cell. Biochem. 118: 1489-1496, 2017. © 2016 Wiley Periodicals, Inc.
