Abstract T-cell receptor (TCR) engineered therapy has recently emerged as a promising adoptive immunotherapy approach for tumor treatment, yet hindered by immune evasion resulting in poor therapeutic efficacy. The introduction of ferroptosis-targeted inducers offers potential solution, they empower T cells to induce ferroptosis and exert influence over the microenvironment. Atovaquone (ATO) stands prospective pharmaceutical candidate with target ferroptosis, effectively provoking an excessive generation accumulation reactive oxygen species (ROS). In this study, we evaluated effectiveness combination comprising ATO TCR-T against hepatocellular carcinoma (HCC), both vitro vivo. results lactate dehydrogenase cytokine assays demonstrated that enhanced cytotoxicity mediated AFP-specific promoted release IFN- γ vitro. Additionally, established HCC xenograft mouse model, combined low-dose exhibited heightened efficacy suppressing growth, no apparent adverse effects, comparable achieved through monotherapy. RNA-seq data unveiled significant activation ferroptosis-related pathway group comparison group. Mechanistically, synergy between augmented cells, while concurrently elevating intracellular mitochondrial levels ROS, expanding labile iron pool, impairing integrity membrane HepG2 cells. This multifaceted interaction culminated potentiation within tumor, primarily induced excess ROS. summary, co-administration vulnerability ferroptosis. susceptibility led inhibition growth stimulation anti-tumor response. These findings suggest repurposing atovaquone cell holds enhance treatment outcomes HCC.

The liver is rich in innate immune cells, such as natural killer (NK) T and Kupffer cells associated with the gut microbiome. These are dysfunctional owing to alcohol consumption. However, there insufficient data on association between microbiome alcoholic disease (ALD). Therefore, purpose of this study was evaluate effects probiotic strains NK ALD patients. In total, 125 human blood samples [control (n = 22), hepatitis 43), cirrhosis 60]) were collected for flow cytometric analysis. C57BL/6J mice divided into four groups (normal, EtOH-fed, 2 EtOH+strain [Phocaeicola dorei Lactobacillus helveticus]). Lymphocytes isolated from mouse livers analyzed using cytometry. frequency increased patients decreased cirrhosis. expression NKp46, an cell-activating receptor, compared that control group. number cytotoxic CD56dimCD16+ significantly reduced We tested effect oral administration P.

The incidence of hepatocellular carcinoma (HCC) ranks first among primary liver cancers, and its mortality rate exhibits a consistent annual increase. treatment HCC has witnessed significant surge in recent years, with the emergence targeted immune therapy as an adjunct to early surgical resection. Adoptive cell (ACT) using tumor-infiltrating lymphocytes (TIL) shown promising results other types solid tumors. This article aims provide comprehensive overview intricate interactions between different TILs their impact on HCC, elucidate strategies for targeting neoantigens through TILs, address challenges encountered TIL therapies along potential solutions. Furthermore, this specifically examines oncogenic signaling pathways activation within tumor microenvironment infiltration dynamics TILs. Additionally, concise is provided regarding preparation techniques update clinical trials investigating TIL-based immunotherapy

Abstract Hepatocellular carcinoma (HCC) remains a significant global health challenge, with over 800,000 new cases diagnosed annually. This comprehensive review examines current surgical approaches and emerging multidisciplinary strategies in HCC treatment. While traditional criteria, such as the Barcelona Clinic Liver Cancer (BCLC) staging system, have been relatively conservative, recent evidence from high-volume Asian centers supports more aggressive carefully selected patients. The discusses evolution of selection including “Borderline Resectable HCC” classification which provides explicit guidance for decision-making. Technical innovations significantly enhanced precision, three-dimensional simulation, intraoperative navigation systems, advancement minimally invasive approaches. evaluates ongoing debate between anatomical versus non-anatomical resection role robotic surgery. In liver transplantation, expanded criteria beyond Milan show promising outcomes, while integration novel biomarkers imaging techniques improves patient selection. preoperative adjuvant therapies is increasingly important, trials demonstrating potential immune checkpoint inhibitors combined anti-VEGF agents both settings. Despite these advances, postoperative recurrence challenge. concludes that successful treatment requires personalized approach, integrating expertise technologies systemic considering individual factors regional variations practice patterns.
