T cells are key drivers of the pathogenesis autoimmune diseases by producing cytokines, stimulating generation autoantibodies, and mediating tissue cell damage. Distinct mitochondrial metabolic pathways govern direction T-cell differentiation function rely on specific nutrients enzymes. Metabolic substrate uptake metabolism form foundational elements for activation, proliferation, differentiation, effector function, contributing to dynamic interplay between immunological signals in coordinating adaptive immunity. Perturbations availability enzyme activity may impair immunosuppressive fostering autoreactive responses disrupting immune homeostasis, ultimately disease pathogenesis. A growing body studies has explored how processes regulate diverse subsets such as systemic lupus erythematosus (SLE), multiple sclerosis (MS), hepatitis (AIH), inflammatory bowel (IBD), psoriasis.

SLC7A11 is importantly in both ferroptosis and disulfidptosis which participated human development homeostasis. By utilizing bioinformatics vitro validation, we explored SLC7A11's role cervical cancer. From the TCGA database, analyzed expression profiles validated its promoting cancer by vitro. Patients were divided into two subgroups according to levels, differentially expressed genes (DEGs) identified between these groups. Then mechanism was then clarified function enrichment analysis. The association immune microenvironment investigated. Finally, explore potential drugs oncoPredict. Our findings suggest that could serve as a valuable prognostic biomarker Besides, positively regulated cells' proliferation, migration invasion. We 113 DEGs subgroups. Functional analysis revealed are linked immune-related pathways. high group showed greater of resting NK cells, neutrophils, M0 macrophages, activated mast whereas low had higher levels dendritic follicular helper T cells. there TMB scores patients with expression. 37 kinds may improve prognosis.

Immunometabolism of ferroptosis in the tumor microenvironment

Frontiers in Oncology, Год журнала: 2024, Номер 14

Опубликована: Авг. 12, 2024

Ferroptosis is an iron-dependent form of cell death that results from excess lipid peroxidation in cellular membranes. Within the last decade, physiological and pathological roles for ferroptosis have been uncovered autoimmune diseases, inflammatory conditions, infection, cancer biology. Excitingly, metabolism may be targeted to induce by cancers are resistant other forms death. sensitivity regulated oxidative stress, metabolism, iron which all influenced tumor microenvironment (TME). Whereas some types shown adapt these stressors, it not clear how immune cells regulate their sensitivities ferroptosis. In this review, we discuss mechanisms different subsets, influences infiltrate TME, interactions can determine epithelial-to-mesenchymal transition (EMT) metastasis. While much focus has placed on inducing cells, important considerations ferroptosis-modulating strategies impact anti-tumor immunity. From perspective, also promising immunotherapies field challenges associated with targeting specific populations.

The solute carrier transporters (SLCs) family in nutrient metabolism and ferroptosis

Biomarker Research, Год журнала: 2024, Номер 12(1)

Опубликована: Сен. 2, 2024

Abstract Ferroptosis is a novel form of programmed cell death caused by damage to lipid membranes due the accumulation peroxides in response various stimuli, such as high levels iron, oxidative stress, metabolic disturbance, etc. Sugar, lipid, amino acid, and iron metabolism are crucial regulating ferroptosis. The solute carrier transporters (SLCs) family, known “metabolic gating” cells, responsible for transporting intracellular nutrients metabolites. Recent studies have highlighted significant role SLCs family members ferroptosis controlling transport nutrients. Here, we summarized function mechanism regulated ion, control nutrients, multiple signaling pathways, with focus on SLC–related that primarily five components: glucose, trace metal other ion. Furthermore, potential clinical applications targeting inducers diseases, including tumors, discussed. Overall, this paper delves into roles ferroptosis, aiming enhance our understanding regulatory mechanisms identify new therapeutic targets applications.

Biosynthetic plasticity enables CD8+ T cell functional resilience under nutrient stress

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Янв. 24, 2025

Summary / Abstract To maintain lineage-specific functions, cells must acquire and allocate nutrients across diverse cellular processes, even in metabolically-dysregulated environments. The mechanisms allowing CD8+ T to immune function perturbed environments are poorly understood. We find that adapt nutrient stresses over time, reconfiguring gene-regulatory metabolic networks license functional recovery. Under acute stress, reorient translational programming, limiting demand while prioritizing stress-sensitive transcriptional responses. Within these responses, the transcription factors ATF4 CEBPG jointly establish an adaptive program, promoting amino acid synthesis uptake maintaining mitochondrial anaplerosis. Despite diminished energetic capacity under environmental this program prevents failure of central carbon metabolism, mitigating stress amplification dysfunction potentiate anti-tumor immunity. Altogether, we demonstrate biosynthetic plasticity via reprioritization confers resilience unfavorable environments, offering novel strategies enhance immunotherapies.

Targeting novel regulated cell death: disulfidptosis in cancer immunotherapy with immune checkpoint inhibitors

Biomarker Research, Год журнала: 2025, Номер 13(1)

Опубликована: Фев. 26, 2025

Abstract The battle against cancer has evolved over centuries, from the early stages of surgical resection to contemporary treatments including chemotherapy, radiation, targeted therapies, and immunotherapies. Despite significant advances in treatment recent decades, these therapies remain limited by various challenges. Immune checkpoint inhibitors (ICIs), a cornerstone tumor immunotherapy, have emerged as one most promising advancements treatment. Although ICIs, such CTLA-4 PD-1/PD-L1 inhibitors, demonstrated clinical efficacy, their therapeutic impact remains suboptimal due patient-specific variability immune resistance. Cell death is fundamental process for maintaining tissue homeostasis function. Recent research highlights that combination induced regulatory cell (RCD) ICIs can substantially enhance anti-tumor responses across multiple types. In cells exhibiting high levels recombinant solute carrier family 7 member 11 (SLC7A11) protein, glucose deprivation triggers programmed (PCD) pathway characterized disulfide bond formation REDOX (reduction-oxidation) reactions, termed “disulfidptosis.” Studies suggest disulfidptosis plays critical role efficacy SLC7A11 cancers. Therefore, investigate potential synergy between this study will explore mechanisms both processes progression, with goal enhancing response targeting intracellular pathway.
