Novel Therapeutic Approaches in Pediatric Acute Lymphoblastic Leukemia.

Acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy, characterized by the clonal proliferation of immature lymphoid precursors. The distinction between B-cell ALL (B-ALL) and T-cell ALL (T-ALL) is fundamental, as each subtype exhibits distinct cytomorphological, genetic, and clinical features influencing prognosis and therapeutic strategies. Conventional multi-phase chemotherapy has significantly improved survival rates, yet its efficacy is limited by severe short- and long-term toxicities, highlighting the need for more selective therapeutic approaches. Advances in mole

Neurotransmitters in cancer: how receptor signaling and posttranslational modifications modulate tumor progression and offer new therapeutic targets.

Recent studies highlight the multifaceted roles of neurotransmitters in tumor immunomodulation, offering novel avenues for increasing therapeutic efficacy. These signaling molecules are classified into cholinergic agents, monoamines, amino acids, and peptides and regulate tumorigenesis, metastasis, and immune evasion via autocrine/paracrine pathways and receptor-mediated interactions. Notably, neurotransmitters influence tumor cell proliferation, apoptosis, and immune cell activity by modulating intracellular signaling cascades through posttranslational modifications (serotonylation and dopami

Advances of HDAC inhibitors in tumor therapy: potential applications through immune modulation.

Histone deacetylase inhibitors (HDAC inhibitors, HDACi) have garnered considerable attention due to their potential in treating various types of malignant tumors. Histone deacetylases (HDACs) not only influence chromatin structure and gene transcription by regulating histone acetylation status but also acetylate various non-histone proteins. They are widely involved in several key biological processes, such as cell cycle regulation, apoptosis induction, and immune responses. HDACi exert their effects by inhibiting HDAC activity; however, these effects are highly concentration-dependent and non

Senescent immune cells in the tumor microenvironment: emerging insights into cancer immunotherapy resistance.

Cancer remains a leading cause of mortality worldwide, with rising incidence and death rates continuing to rise. While conventional treatments such as surgery, radiotherapy, and chemotherapy form the backbone of cancer care, they are often limited by adverse effects, recurrence risk, and incomplete tumor eradication. Tumor immunotherapy-particularly immune checkpoint inhibitors and chimeric antigen receptor (CAR) T cell therapy-has emerged as a transformative approach by activating and reprogramming anti-tumor immune responses. Despite these advances, significant challenges persist, including

Molecular Mechanisms Underlying Curcumin-Mediated Therapeutic Effects in Type 2 Diabetes and Cancer.

The growing prevalence of age-related diseases, especially type 2 diabetes mellitus (T2DM) and cancer, has become global health and economic problems. Due to multifactorial nature of both diseases, their pathophysiology is not completely understood so far. Compelling evidence indicates that increased oxidative stress, resulting from an imbalance between production of reactive oxygen species (ROS) and their clearance by antioxidant defense mechanisms, as well as the proinflammatory state contributes to the development and progression of the diseases. Curcumin (CUR; diferuloylmethane), a well-kn

A Rare and Fatal Case of Hemophagocytic Lymphohistiocytosis Associated with Sarcoidosis.

BACKGROUND Sarcoidosis is a systemic inflammatory disorder characterized by a classic pathologic feature of non-caseating granulomas involving any organ system. Hemophagocytic lymphohistiocytosis (HLH) is a catastrophic cytokine surge characterized by dysregulation of the macrophage response, which can be rapidly fatal. Recognition of HLH has been increasing over the past decade. HLH can present with features of sepsis that can make the diagnosis challenging and requires high clinical suspicion.

Heterogeneous Contributing Factors in MPM Disease Development and Progression: Biological Advances and Clinical Implications.

Malignant pleural mesothelioma (MPM) tumors are remarkably aggressive and most patients only survive for 5-12 months; irrespective of stage; after primary symptoms appear. Compounding matters is that MPM remains unresponsive to conventional standards of care; including radiation and chemotherapy. Currently; instead of relying on molecular signatures and histological typing; MPM treatment options are guided by clinical stage and patient characteristics because the mechanism of carcinogenesis has not been fully elucidated; although about 80% of cases can be linked to asbestos exposure.

Similarly, 73% of patients in DREAMM-2 had keratopathy (71% in 2.5 mg/kg versus 75% in 3.4 mg/kg) with the most common symptoms being blurred vision and dry eyes. Ocular

Chronic stress in solid tumor development: from mechanisms to interventions.

Chronic stress results in disturbances of body hormones through the neuroendocrine system. Cancer patients often experience recurrent anxiety and restlessness during disease progression and treatment, which aggravates disease progression and hinders treatment effects. Recent studies have shown that chronic stress-regulated neuroendocrine systems secret hormones to activate many signaling pathways related to tumor development in tumor cells. The activated neuroendocrine system acts not only on tumor cells but also modulates the survival and metabolic changes of surrounding non-cancerous cells.

Вирус Эпштейн-Барр, витамин D и иммунная реакция: связи с последствиями множественного склероза.

Множественный склероз (MS) — аутоиммунное заболевание центральной нервной системы (CNS) без какого-либо окончательного запуска. Однако эпидемиологические исследования показывают, что важными факторами риска являются такие экологические факторы, как инфекция вируса Эпштейн-Барр (ЭБВ) и низкий уровень витамина D (вид D) у генетически предрасположенных лиц. Одно из ведущих предложений заключается в том, что EBV приводит в действие MS с помощью таких механизмов, как молекулярная имитация, где активированные автоматически реактивные B и T лимфоциты ошибочно нацелены на самоантигены.
