Biology of stem cell paradox: a double-edged sword-implications for cancer therapy.

This comprehensive review investigates the complex interactions between oncogenesis and stem cells, underscoring the crucial importance of cancer stem cells (CSCs) in the mechanisms of tumorigenesis, metastatic dissemination, and resistance to therapeutic interventions. CSCs constitute a distinct subset within neoplasms, defined by unique characteristics such as the ability to self-renew, the potential to differentiate into various cellular phenotypes, and an inherent resistance to conventional treatment strategies. It is hypothesized that these properties are regulated by a multitude of signa

Strategic Combinations of Antibody-Drug Conjugates from 2023 to 2025: From Dual Therapies to Innovative ADC-Based Regimens.

Antibody-drug conjugates (ADCs) are a potent class of targeted cancer therapies that combine the specificity of monoclonal antibodies with the cytotoxic potency of chemotherapeutic agents. By targeting tumor cells with minimal impact on healthy tissues, ADCs achieve a favorable balance between efficacy and systemic toxicity. This therapeutic modality has demonstrated significant clinical success, as evidenced by the FDA approval of 15 ADCs by 2025, with one later withdrawn due to safety concerns, and indications continuing to expand across various cancer types. Beyond monotherapy, there is gro

CAR-T-Cell-Based Cancer Immunotherapies: Potentials, Limitations, and Future Prospects.

Cancer encompasses various elements occurring at the cellular and genetic levels, necessitating an immunotherapy capable of efficiently addressing both aspects. T cells can combat cancer cells by specifically recognizing antigens on them. This innate capability of T cells has been used to develop cellular immunotherapies, but most of them can only target antigens through major histocompatibility complexes (MHCs). New gene-editing techniques such as clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein 9 (CRISPR-cas9) can precisely edit the DNA sequences. CRISPR-c

Contribution of Macrophages and T Cells in Skeletal Metastasis.

Bone is a common site for metastases with a local microenvironment that is highly conducive for tumor establishment and growth. The bone marrow is replete with myeloid and lymphoid linage cells that provide a fertile niche for metastatic cancer cells promoting their survival and growth. Here, we discuss the role of macrophages and T cells in pro- and anti-tumoral mechanisms, their interaction to support cancer cell growth, and their contribution to the development of skeletal metastases. Importantly, immunotherapeutic strategies targeting macrophages and T cells in cancer are also discussed in

CAR-T cell therapy: A new dawn in the treatment of autoimmune disease.

Autoimmune diseases (AIDs) are a class of diseases caused by autoimmune intolerance, which can be divided into systemic and organ-specific diseases. AIDs affect approximately 10% of the global population and rank among the leading causes of disability and mortality. At present, immunosuppressive agents are the first choice for the treatment of AIDs. B-cell-targeted therapies-particularly CD20 monoclonal antibodies-have brought new hope for systemic AIDs, yet a subset of patients still respond poorly. As a rapidly developing cellular immunotherapy technology, Chimeric antigen receptor T cell (C

Hematopoietic Niche Hijacking in Bone Metastases: Roles of Megakaryocytes, Erythroid Lineage Cells, and Perivascular Stromal Subsets.

Bone metastases mark a critical and often terminal phase in cancer progression, where disseminated tumor cells (DTCs) manage to infiltrate and exploit the complex microenvironments of the bone marrow. While most current therapies focus on the well-known late-stage "vicious cycle" of osteolysis, they often overlook the earlier stages, namely, tumor cell colonization and dormancy. During these early phases, cancer cells co-opt hematopoietic stem cell (HSC) niches, using them as sanctuaries for long-term survival. In this review, we bring together emerging insights that highlight a trio of undera

The role of CD8+ T cells in the immunoregulation of osteoporosis.

INTRODUCTION: Osteoporosis weakens the skeleton by lowering bone mass and damaging bone microarchitecture. A growing body of evidence points to disruptions in osteoimmune homeostasis as a key driver of this disease. In particular, apoptosis of bone cells and immune cells appears to be a critical contributing mechanism. Within the bone marrow, CD8+ T cells display a surprising functional duality: whether they protect bone or promote its loss depends heavily on local signals. Under healthy conditions or after mechanical loading, activated CD8+ T cells help maintain bone mass. They do so mainly b

Next-Generation HDAC Inhibitors: Advancing Zinc-Binding Group Design for Enhanced Cancer Therapy.

Histone deacetylases (HDACs) are pivotal epigenetic regulators that control gene expression, cell proliferation, and differentiation, and their dysregulation is closely associated with the onset and progression of multiple cancers. The therapeutic importance of these enzymes is reflected by FDA approval of HDAC inhibitors for oncology indications. Despite this clinical success, most FDA-approved agents employ conventional zinc-binding groups (ZBGs) such as hydroxamic acid and 2-aminoanilide, which are frequently linked to metabolic instability, genotoxicity, and poor pharmacokinetic behavior.
