Fine-Tuning through Generations: Advances in Structure and Production of CAR-T Therapy.

Chimeric antigen receptor (CAR)-T cell therapy is a promising form of immunotherapy that has seen significant advancements in the past few decades. It involves genetically modifying T cells to target cancer cells expressing specific antigens, providing a novel approach to treating various types of cancer. However, the initial success of first-generation CAR-T cells was limited due to inadequate proliferation and undesirable outcomes. Nonetheless, significant progress has been made in CAR-T cell engineering, leading to the development of the latest fifth-generation CAR-T cells that can target m

Clinical application of cytokine-induced killer cells in cancer immunotherapy.

Cytokine-induced killer (CIK) cells exhibit potent antitumor activity with reduced dependence on strict MHC compatibility, mediated by a combination of T-cell receptor (TCR)-dependent recognition and natural killer (NK)-like, MHC-unrestricted cytotoxicity. This narrative review synthesizes evidence from clinical trial evaluations, including 48 published studies. We examine strategies to enhance CIK function, such as engineering, combination with checkpoint inhibitors, and co-administration with dendritic cells. CIK cell therapy effectively reduces post-treatment recurrence in the adjuvant sett

Nucleo-cytoplasmic transport as a therapeutic target of cancer.

Shuttling of specific proteins out of the nucleus is essential for the regulation of the cell cycle and proliferation of both normal and malignant tissues. Dysregulation of this fundamental process may affect many other important cellular processes such as tumor growth, inflammatory response, cell cycle, and apoptosis. It is known that XPO1 (Exportin-1/Chromosome Region Maintenance 1/CRM1) is the main mediator of nuclear export in many cell types. Nuclear proteins exported to the cytoplasm by XPO1 include the drug targets topoisomerase IIα (topo IIα) and BCR-ABL and tumor suppressor proteins s

KRAS mutation in secondary malignant histiocytosis arising from low grade follicular lymphoma.

BackgroundTransformation of follicular lymphoma most typically occurs as diffuse large B-cell lymphoma, however other forms of transformation such as classic Hodgkin lymphoma and lymphoblastic transformation can occur. Secondary malignant histiocytosis also represents a rare form of transformation, which is thought to occur due to a process of transdifferentiation whereby the lymphoma cells exhibit lineage plasticity and lose all evidence of B-cell phenotype and instead acquire the phenotype of a histiocytic neoplasm. Little is known about the underlying genetic alterations that occur during t

MDM2/X Inhibitors as Radiosensitizers for Glioblastoma Targeted Therapy.

Inhibition of the MDM2/X-p53 interaction is recognized as a potential anti-cancer strategy, including the treatment of glioblastoma (GB). In response to cellular stressors, such as DNA damage, the tumor suppression protein p53 is activated and responds by mediating cellular damage through DNA repair, cell cycle arrest and apoptosis. Hence, p53 activation plays a central role in cell survival and the effectiveness of cancer therapies. Alterations and reduced activity of p53 occur in 25-30% of primary GB tumors, but this number increases drastically to 60-70% in secondary GB. As a result, reacti

Dissecting the effects of 223Radium on the bone microenvironment.

Radium-223 (223Ra) is a bone-seeking, alpha-particle-emitting radionuclide that is approved for the treatment of patients with metastatic prostate cancer and is currently being tested in clinical trials for primary and metastatic cancers to the bone. 223Ra accumulates in mineralized bone areas with high bone turnover, where its effects are confined within 100 μm of the bone-marrow interface due to the short tissue penetrance of the alpha particles. A recent clinical study has shown a significantly increased fracture rate associated with the administration of 223Ra, mostly in tumor-free bones.

CAR-T Cell Therapy-An Overview of Targets in Gastric Cancer.

Gastric cancer (GC) is one of the most commonly diagnosed malignancies and, unfortunately, still has a high mortality rate. Recent research points to CAR-T immunotherapy as a promising treatment for this disease. Using genetically engineered T cells designed to target a previously selected antigen, researchers are able to harness the natural anti-tumor activity of T cells. For therapy to be successful, however, it is essential to choose antigens that are present on tumor cells but not on healthy cells. In this review, we present an overview of the most important targets for CAR-T therapy in th

P2X7 Receptor Function in Bone-Related Cancer.

Modulation of tumor microenvironment by different mediators is central in determining neoplastic formation and progression. Among these molecules extracellular ATP is emerging as a good candidate in promoting cell growth, neovascularization, tumor-host interactions, and metastatization. This paper summarizes recent findings on expression and function of P2X7 receptor for extracellular ATP in primary and metastatic bone cancers. Search of mRNA expression microchip databases and literature analysis demonstrate a high expression of P2X7 in primary bone tumors as well as in other malignancies such

γδ T cells are a unique subset of lymphocytes with both innate and adaptive features. They recognize and eradicate various hematological malignancies through different mechanisms, employing factors including γδ TCR, NKR, NKG2D, TRAIL, and perforin/granzyme. They also modulate other immune cells to enhance their antitumor activity. Moreover, γδ T cells have potent antiviral functions after hematopoietic stem cell transplantation (HSCT), which may improve the outcome of patients with hematological malignancies. In this review, we summarize the current knowledge on γδ T cell biology and function

Hematopoietic stem cell microtransplantation: current situation and challenges.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) stands as a cornerstone in the treatment of hematological malignancies, recognized for its remarkable efficacy. However, the persistent challenge of graft-versus-host disease (GVHD) continues to represent a significant barrier, often being the leading cause of nonrelapse mortality after allo-HSCT. To address this limitation, hematopoietic stem cell microtransplantation (MST) has emerged as a novel therapeutic strategy that synergistically combines chemotherapy, allo-HSCT, and cellular immunotherapy. This innovative approach is desi
