Background and Aims: Guidelines recommend intravenous (IV) albumin after large-volume paracentesis to prevent post-paracentesis circulatory dysfunction and acute kidney injury (AKI). However, real-world effects of albumin on paracentesis outcomes in outpatient settings are understudied. We aimed to address this using national data from a well-established cirrhosis cohort. Methodology: This was a retrospective cohort study of Veterans with cirrhosis undergoing outpatient paracentesis. Albumin administration and paracentesis volumes were extracted, in addition to hospitalization for AKI within 7 days of outpatient paracentesis. Mixed-effects logistic regression identified factors associated with albumin administration and the association between albumin and incident AKI hospitalization. Results: Among 9,467 patients who received 56,941 outpatient paracentesis procedures, IV albumin was used 17% of the time. Use was higher with MELD-Na (OR 1.02, 95% CI 1.02-1.03, p <0.001), lower eGFR (OR 3.06 for <30 vs. ≥90 mL/min/1.73 m², 95% CI 2.64-3.54, p <0.001), and hepatic encephalopathy (OR 1.22, 95% CI 1.13-1.33, p <0.001). Albumin administration was associated with lower odds of AKI-related hospitalizations (OR 0.66, 95% CI 0.54–0.81, p <0.001) with greater effect observed in patients with lower eGFR (interaction p -value=0.03). In a subcohort of 48,401 procedures with available dosing information, higher-dose albumin (≥6-8 g/L removed) was associated with lower odds AKI hospitalization (OR 0.36, 95% CI 0.20-0.64, p =0.001) with similar associations noted irrespective of paracentesis volume. Conclusion: Albumin administration after outpatient paracentesis was associated with a reduced risk of hospitalization with AKI, with greater effect at lower eGFRs. Strategies that tailor albumin administration based on intravascular volume and hemodynamics should be prospectively tested.
背景和目的:指南推荐在大容量穿刺后静脉注射白蛋白以预防穿刺后循环功能障碍和急性肾损伤(AKI)。然而,白蛋白对门诊穿刺结果的实际影响尚未得到充分研究。我们的目的是通过一个完善的肝硬化队列的国家数据来解决这个问题。方法:这是一项对接受门诊穿刺的肝硬化退伍军人的回顾性队列研究。提取白蛋白给药量和穿刺量,并在门诊穿刺后7天内因AKI住院。混合效应logistic回归确定了与白蛋白给药相关的因素以及白蛋白与AKI住院事件之间的关联。结果:在接受56,941例门诊穿刺手术的9,467例患者中,静脉注射白蛋白的比例为17%。MELD-Na的使用率较高(OR 1.02, 95% CI 1.02-1.03, p <0.001), eGFR较低(OR 3.06,≥90 mL/min/1.73 m²,95% CI 2.64-3.54, p <0.001),肝性脑病(OR 1.22, 95% CI 1.13-1.33, p <0.001)。白蛋白给药与aki相关住院的几率较低相关(OR 0.66, 95% CI 0.54-0.81, p <0.001),在eGFR较低的患者中观察到更大的影响(相互作用p值=0.03)。在一项包含48,401例可获得剂量信息的手术亚队列中,高剂量白蛋白(≥6-8 g/L)与AKI住院率较低相关(OR 0.36, 95% CI 0.20-0.64, p =0.001),且与穿刺容积无关。结论:门诊穿刺术后白蛋白给药与AKI住院风险降低相关,egfr较低时效果更明显。根据血管内容量和血流动力学来调整白蛋白给药的策略应该进行前瞻性试验。

Background and Aims: Immune checkpoint blockade (ICB) shows therapeutic promise in hepatocellular carcinoma (HCC) but is associated with suboptimal responses in patients. Progenitor exhausted T (Tpex) cells are key responders to ICB, but the regulatory mechanisms regarding Tpex maintenance in HCC remain elusive. Approach and Results: Through an integrated analysis of HCC single-cell RNA-sequencing datasets, we constructed an exhausted CD8 + T cell atlas and identified FYN as a marker of Tpex cells in ICB responders. FYN deficiency in CD8 + T cells induced LCK hyperactivation, which drove terminal exhaustion under high-affinity antigen stimulation. Mechanistically, LCK hyperactivation disrupted metabolic homeostasis by triggering excessive glycolysis and impairing mitochondrial function in Tpex cells. Conversely, LCK inhibition elevated compensatory FYN activity, restored mitochondrial fitness and preserved Tpex cell stemness. In preclinical HCC models, transient LCK inhibition during T cell expansion enhanced adoptive cell therapy efficacy by increasing Tpex cell persistence and stemness. Besides, preemptive low-dose LCK inhibition prior to anti-PD1 therapy expanded the Tpex cell pool, reduced terminal exhaustion, and improved therapeutic outcomes. Conclusions: This study establishes the balance between SRC kinases FYN and LCK as a critical regulator of the terminal exhaustion of Tpex cell through metabolic reprogramming. The finding suggests that modulating the FYN/LCK kinase balance is a promising strategy to overcome immunotherapy resistance in HCC.
背景和目的:免疫检查点阻断(ICB)在肝细胞癌(HCC)中显示出治疗前景,但与患者的次优反应相关。祖细胞耗竭T细胞(Tpex)是ICB的关键应答者,但HCC中Tpex维持的调控机制仍不明确。方法和结果:通过对HCC单细胞rna测序数据集的综合分析,我们构建了一个耗尽CD8 + T细胞图谱,并确定FYN是ICB应答者中Tpex细胞的标记物。CD8 + T细胞FYN缺乏诱导LCK过度激活,在高亲和力抗原刺激下导致终末衰竭。在机制上,LCK过度激活通过触发过度糖酵解和损害Tpex细胞的线粒体功能来破坏代谢稳态。相反,LCK抑制可提高代偿性FYN活性,恢复线粒体健康并保持Tpex细胞的干细胞性。在临床前HCC模型中,T细胞扩增过程中短暂的LCK抑制通过增加Tpex细胞的持久性和干性来增强过继细胞治疗的效果。此外,在抗pd1治疗前先发制人的低剂量LCK抑制扩大了Tpex细胞池,减少了末期衰竭,改善了治疗结果。结论:本研究确定了SRC激酶FYN和LCK之间的平衡是Tpex细胞通过代谢重编程最终衰竭的关键调节因子。这一发现表明,调节FYN/LCK激酶平衡是克服HCC免疫治疗耐药的一种有希望的策略。

Background and Aims: Severe (Pi*ZZ) and heterozygous (Pi*MZ) alpha-1 antitrypsin deficiency (AATD) confer increased liver- and lung-related mortality, but the phenotype is highly variable. We aimed to evaluate the impact of obesity and diabetes mellitus on individuals with/without AATD. Approach and Results: Cohort 1 prospectively recruited 1678 Pi*ZZ adults from an international initiative with a systematic liver assessment. 983 participants had a longitudinal follow-up. The data were compared to 16,768 Pi*MZ and 415,208 non-AATD individuals from the United Kingdom Biobank (cohort 2). Findings were ascertained by multivariable adjustment and propensity score matching. At baseline, diabetes was present in 52 (3%), overweight (BMI 25.0-29.9 kg/m 2 ) in 540 (52%) and obesity (BMI≥30 kg/m 2 ) in 266 (32%) Pi*ZZ adults. Pi*ZZ individuals with diabetes showed higher transaminases and surrogates of advanced liver fibrosis (APRI≥1.0, LSM≥15 kPa) were four to six times more common (adjusted Odds Ratio (aOR) 5.7/4.3, p <0.01). Elevated transaminases were rare among lean Pi*ZZ subjects, but more common in overweight (aOR 1.5/2.0) and obese Pi*ZZ participants (aOR 2.1/2.9). APRI≥1.0 was more than four times elevated in obese vs. lean Pi*ZZ individuals (aOR 4.1, p <0.001). During a median follow-up of 4.2 years, 54 Pi*ZZ participants experienced a hepatic and 64 a pulmonary endpoint. While Pi*ZZ participants with diabetes/obesity had an increased risk of hepatic endpoints (aHR 6.03/3.38, p <0.001) compared with non-diabetic/lean Pi*ZZ subjects, overweight was associated with a decreased risk of pulmonary endpoints (aHR 0.45, p =0.004). Conclusions: Our data demonstrate the interaction between genetic and metabolic risk factors in AATD and provide evidence for patient management.
背景和目的:严重(Pi*ZZ)和杂合(Pi*MZ) α -1抗胰蛋白酶缺乏症(AATD)会增加肝脏和肺部相关的死亡率,但其表型是高度可变的。我们旨在评估肥胖和糖尿病对患有/不患有AATD的个体的影响。方法和结果:队列1前瞻性地从一项系统肝脏评估的国际倡议中招募了1678名Pi*ZZ成年人。983名参与者进行了纵向随访。将数据与来自英国生物银行(队列2)的16,768名Pi*MZ和415,208名非aatd个体进行比较。通过多变量调整和倾向评分匹配来确定研究结果。基线时,52名(3%)Pi*ZZ成人患有糖尿病,540名(52%)存在超重(BMI 25.0-29.9 kg/ m2), 266名(32%)存在肥胖(BMI≥30 kg/ m2)。Pi*ZZ糖尿病患者转氨酶较高,晚期肝纤维化(APRI≥1.0,LSM≥15 kPa)的代物发生率为4 ~ 6倍(校正优势比(aOR) 5.7/4.3, p <0.01)。转氨酶升高在瘦Pi*ZZ受试者中罕见,但在超重(aOR 1.5/2.0)和肥胖Pi*ZZ受试者(aOR 2.1/2.9)中更为常见。肥胖Pi*ZZ个体的APRI≥1.0比瘦弱Pi*ZZ个体高4倍以上(aOR 4.1, p <0.001)。在4.2年的中位随访期间,54名Pi*ZZ参与者经历了肝脏终点和64名肺部终点。与非糖尿病/瘦Pi*ZZ受试者相比,患有糖尿病/肥胖的Pi*ZZ受试者肝脏终点风险增加(aHR 6.03/3.38, p <0.001),而超重与肺部终点风险降低相关(aHR 0.45, p =0.004)。结论:我们的数据显示了AATD中遗传和代谢危险因素之间的相互作用,并为患者管理提供了证据。

Background and aims: Alcohol-associated liver disease (ALD) represents a global health burden with limited therapeutic strategies. While the hepatocyte transcription factor CCAAT/enhancer-binding protein α (CEBPA) regulates hepatic gene expression and liver fibrosis, its role in ALD pathogenesis remains undefined. Here, hepatocyte CEBPA was examined for its modulation of alcohol-associated hepatic steatosis and ALD. Approach and Results: Hepatocyte-specific CEBPA knockout mice, AAV transduction studies and reporter gene assays, were carried out using acute and chronic mouse ALD models. Western blotting was performed on liver tissues from human ALD patients. Hepatic CEBPA expression decreased during ALD progression in human patient cohorts. Hepatocyte-specific Cebpa -knockout mice exhibited exacerbated alcohol-associated steatosis in both the acute and chronic ALD models. Inducible ablation of CEBPA in hepatocytes during late-stage ALD, accelerated disease progression, demonstrating the persistent protective function of CEBPA. Global transcriptomics identified Orm1 encoding orosomucoid 1 (ORM1) as the top CEBPA-upregulated gene in hepatocytes, while reporter assays and chromatin immunoprecipitation revealed that CEBPA directly activates Orm1 transcription by binding CEBPA response elements upstream of the Orm1 promoter. Loss of hepatocyte ORM1 potentiated the severity of ALD in mice. Conversely, restoring CEBPA or ORM1 via intravenous AAV8 delivery or administering recombinant ORM1 protein, rescued hepatic lipid accumulation and reduced disease progression. Consistently, serum ORM1, a hepatocyte-secreted hepatokine, inversely correlated with ALD severity in patients. Conclusions: These findings identify the hepatocyte CEBPA-ORM1 axis as a critical suppressor of ALD, offering therapeutic targets and nominating serum ORM1 as a potential biomarker for staging ALD severity.
背景和目的:酒精相关性肝病(ALD)是一种全球健康负担,治疗策略有限。虽然肝细胞转录因子CCAAT/增强子结合蛋白α (CEBPA)调节肝脏基因表达和肝纤维化,但其在ALD发病机制中的作用尚不清楚。本研究检测了肝细胞CEBPA对酒精相关性肝脂肪变性和ALD的调节作用。方法和结果:采用急性和慢性小鼠ALD模型,对肝细胞特异性CEBPA敲除小鼠进行AAV转导研究和报告基因检测。对人ALD患者肝组织进行Western blotting。在人类患者队列中,肝脏CEBPA表达在ALD进展过程中下降。肝细胞特异性Cebpa敲除小鼠在急性和慢性ALD模型中均表现出加剧的酒精相关脂肪变性。在晚期ALD期间,诱导消融肝细胞中的CEBPA,加速疾病进展,证明CEBPA的持续保护功能。全球转录组学鉴定出Orm1编码orosomucoid 1 (Orm1)是肝细胞中CEBPA上调最多的基因,而报告基因分析和染色质免疫沉淀显示,CEBPA通过结合Orm1启动子上游的CEBPA应答元件直接激活Orm1的转录。肝细胞ORM1的缺失增强了小鼠ALD的严重程度。相反,通过静脉注射AAV8或给予重组ORM1蛋白来恢复CEBPA或ORM1,可以挽救肝脏脂质积累并减少疾病进展。一致地,血清ORM1(一种肝细胞分泌的肝因子)与患者的ALD严重程度呈负相关。结论:这些发现确定了肝细胞CEBPA-ORM1轴是ALD的关键抑制因子,提供了治疗靶点,并将血清ORM1作为ALD严重程度分期的潜在生物标志物。

The hepatitis C virus (HCV) is a major cause of liver cirrhosis and cancer in humans, and an effective vaccine is urgently needed. Here, we evaluated the immunogenicity of a DNA prime and modified vaccinia Ankara (MVA) boost vaccine expressing H77 genotype 1a HCV immunogens to induce both T and B cell responses. The non-structural (NS) immunogens expressed NS3, NS4, and NS5. The structural plus p7 immunogen (S-p7) expressed Core, E1, E2 and p7. We tested the immunogenicity of these vaccines in mice and rhesus macaques (RMs) with 2 or 3 doses of DNA followed by 1 or 2 doses of MVA. The NS immunogens induced CD4 and CD8 T cell responses against multiple NS proteins with a dominant CD4 T cell response to NS3 and NS5, and a dominant CD8 T cell response to NS3. The S-p7 immunogen induced E2-binding IgG titer with neutralizing activity against autologous and heterologous HCV pseudovirus particles. Additionally, the S-p7 immunogen induced a CD4 and CD8 T cell response directed against E1 (0.08% and 0.09%, respectively) and E2 (0.13% and 0.18%, respectively) in RMs. Co-delivery of S-p7 and NS vaccines elicited a T cell response against the majority of HCV proteins, which was comparable to the T cell response observed in humans with HCV resolution. These findings show that the DNA/MVA prime/boost vaccination induces a strong and broad CD4 and CD8 T cell response to multiple HCV proteins and a neutralizing antibody response. These results aid in the development of vaccines for HCV.
丙型肝炎病毒(HCV)是人类肝硬化和癌症的主要病因,迫切需要一种有效的疫苗。在这里,我们评估了表达H77基因型1a HCV免疫原的DNA引物和修饰的安卡拉牛痘(MVA)增强疫苗诱导T细胞和B细胞反应的免疫原性。非结构性免疫原表达NS3、NS4和NS5。结构加p7免疫原(S-p7)表达Core、E1、E2和p7。我们在小鼠和恒河猴(RMs)中测试了这些疫苗的免疫原性,先注射2或3剂DNA,然后注射1或2剂MVA。NS免疫原诱导CD4和CD8 T细胞对多种NS蛋白产生应答,CD4 T细胞对NS3和NS5产生显性应答,CD8 T细胞对NS3产生显性应答。S-p7免疫原诱导e2结合IgG滴度,对自身和外源HCV假病毒颗粒具有中和活性。此外,S-p7免疫原诱导针对E1(分别为0.08%和0.09%)和E2(分别为0.13%和0.18%)的CD4和CD8 T细胞应答。S-p7和NS疫苗的共同递送引起了针对大多数HCV蛋白的T细胞应答,这与在HCV分解的人身上观察到的T细胞应答相当。这些发现表明,DNA/MVA启动/增强疫苗可诱导CD4和CD8 T细胞对多种HCV蛋白产生强烈和广泛的应答,并产生中和抗体应答。这些结果有助于开发丙肝病毒疫苗。

BACKGROUNDAminoacyl-tRNA synthetases (ARSs) exert canonical and emerging non-canonical roles in cancer. Given the frequent alterations in aspartate metabolism in hepatocellular carcinoma (HCC), we investigated the clinical and functional significance of aspartyl-tRNA synthetase (DARS1) in HCC.METHODSDARS1 expression was evaluated in tumor and matched non-tumoral tissues, in silico cohorts, and plasma samples. Functional assays were performed in liver cancer cell lines after genetic and pharmacological modulation of DARS1. In vivo validation was conducted using xenograft and orthotopic tumor models. Protein interactors of DARS1 were characterized by quantitative proteomics and confirmed by biochemical approaches.RESULTSDARS1 abundance was increased in HCC, especially in highly aggressive tumours, and in plasma from HCC patients. DARS1 overexpression increased aggressiveness in vitro and xenograft and orthotopic tumour formation in vivo, while genetic and pharmacological blockade of DARS1 impaired stemness in vitro without affecting normal-like cells. Proteomic profiling revealed a significant enrichment of high-aspartate proteins in DARS1-overexpressing cells, demonstrating a reshaping of the HCC proteome. Beyond its canonical role, DARS1 was found in the nucleus interacting with members of the SAGA transcriptional co-activator complex, including SUPT7L. This interaction affected MYC regulation, as DARS1 depletion reduced MYC protein levels, increased its phosphorylation, and enhanced drug-induced senescence, linking DARS1-SAGA activity to MYC-driven oncogenic pathways.CONCLUSIONSDARS1 is frequently overexpressed in HCC and detectable in plasma, supporting its potential as liquid biopsy biomarker. Functionally, DARS1 represents a novel vulnerability of HCC, acting through both proteome reshaping and non-canonical nuclear interactions with the SAGA complex that modulate MYC activity.
氨基酰基- trna合成酶(ARSs)在癌症中发挥着典型和新兴的非典型作用。鉴于肝细胞癌(HCC)中天冬氨酸代谢的频繁改变,我们研究了天冬氨酸- trna合成酶(DARS1)在HCC中的临床和功能意义。方法在肿瘤和匹配的非肿瘤组织、计算机队列和血浆样本中评估sdars1的表达。在基因和药理学调控DARS1后,对肝癌细胞系进行功能检测。使用异种移植和原位肿瘤模型进行体内验证。用定量蛋白质组学方法对DARS1蛋白相互作用物进行了表征,并用生化方法对其进行了验证。结果在HCC中,尤其是高侵袭性肿瘤和HCC患者血浆中,dars1丰度升高。DARS1过表达增加了体外侵袭性以及体内异种移植物和原位肿瘤的形成,而遗传和药物阻断DARS1在体外损害了干细胞性,而不影响正常样细胞。蛋白质组学分析显示,在dars1过表达的细胞中,高天冬氨酸蛋白显著富集,证明了HCC蛋白质组的重塑。除了其典型的作用,DARS1在细胞核中被发现与SAGA转录共激活因子复合体的成员相互作用,包括SUPT7L。这种相互作用影响MYC调控,因为DARS1缺失降低了MYC蛋白水平,增加了其磷酸化,并增强了药物诱导的衰老,将DARS1- saga活性与MYC驱动的致癌途径联系起来。结论sdars1在HCC中经常过表达,且可在血浆中检测到,支持其作为液体活检生物标志物的潜力。在功能上,DARS1代表了HCC的一种新的脆弱性,通过蛋白质组重塑和与SAGA复合物的非规范核相互作用来调节MYC活性。

BACKGROUNDOncostatin M (OSM) has been shown to contribute to metabolic dysfunction-associated steatohepatitis (MASH) progression to hepatocellular carcinoma (HCC). Here we investigated its role in shaping an immunosuppressive tumor microenvironment (TIME) in MASH-HCCs.APPROACHOSM role was investigated through combined analyses of MASLD/MASH patients with or without HCC, MASH-related HCCs originating in wild type and hepatocyte-specific OSM receptor-β (hOSMRβ-/-) deficient mice and in vitro experiments performed on liver cancer and immune cell lines.RESULTSAnalysis of OSM-expressing HCC patients with mixed etiology (TCGA-database) revealed a positive correlation between OSM transcripts and those of several TIME markers. A similar pattern was also observed in murine MASH-HCC tumors. hOSMRβ-/- mice had significantly reduced tumor volume and weight without altering macrophage infiltration and OSM production. However, TIME markers transcripts were lower in HCCs from hOSMRβ-/- mice. These effects associated with a lowering in tumor STAT3 phosphorylation and COX-2 activity. Single-cell RNAseq analysis of human HCCs identified malignant hepatocyte as source of CCL15, a cytokine associated with immunosuppression in HCCs. Circulating CCL15 was markedly elevated in either human and rodent MASH-HCCs and significantly reduced by hOSMRβ deletion. Blocking autocrine OSM signaling in HepG2 or Huh7 cells overexpressing OSM reduced STAT3 phosphorylation, CCL15 production and prevented TIME markers expression by co-cultured macrophage-derived THP1 cells.CONCLUSIONSOur findings provide compelling evidence for an autocrine role of OSM/OSMRβ axis in promoting CCL15 production by tumor cells which, in turn, stimulates an immunosuppressive TIME in MASH-HCCs, suggesting OSM as a potential therapeutic target for HCC treatment.
背景:doncostatin M (OSM)已被证明与代谢功能障碍相关的脂肪性肝炎(MASH)进展为肝细胞癌(HCC)有关。在这里,我们研究了它在mash - hcc中形成免疫抑制肿瘤微环境(TIME)的作用。通过对伴有或不伴有HCC的MASLD/MASH患者、源自野生型和肝细胞特异性OSM受体-β (hOSMRβ-/-)缺陷小鼠的MASH相关HCC以及肝癌和免疫细胞系的体外实验,研究了APPROACHOSM的作用。结果对混合病因表达OSM的HCC患者的分析(tcga数据库)显示OSM转录物与多个TIME标记物呈正相关。在小鼠MASH-HCC肿瘤中也观察到类似的模式。在不改变巨噬细胞浸润和OSM产生的情况下,hOSMRβ-/-小鼠的肿瘤体积和重量显著减少。然而,在来自hOSMRβ-/-小鼠的hcc中,TIME标记物转录较低。这些作用与肿瘤STAT3磷酸化和COX-2活性的降低有关。人类hcc的单细胞RNAseq分析发现,恶性肝细胞是CCL15的来源,CCL15是一种与hcc免疫抑制相关的细胞因子。在人和啮齿类msh - hcc中,循环CCL15显著升高,hOSMRβ缺失后循环CCL15显著降低。在过表达OSM的HepG2或Huh7细胞中,阻断自分泌OSM信号传导可减少STAT3磷酸化、CCL15的产生,并阻止共培养巨噬细胞来源的THP1细胞表达TIME标记物。结论本研究结果提供了令人信服的证据,证明OSM/OSMRβ轴在促进肿瘤细胞产生CCL15中的自分泌作用,进而刺激msh -HCC中的免疫抑制TIME,提示OSM可能是HCC治疗的潜在治疗靶点。

BACKGROUND AND AIMSWhile gemcitabine/cisplatin (GC) combined with anti-PD-L1 is a first-line regimen for advanced intrahepatic cholangiocarcinoma (ICC), efficacy remains limited and toxicity significant, highlighting the need to optimize therapeutic strategy. We sought to investigate whether low-dose GC (LDGC) could unleash anti-PD-L1-mediated antitumor immunity along with reduced toxicity.APPROACH AND RESULTSMultiple preclinical ICC mouse models were used to assess the anti-tumor efficacy and toxicity of LDGC combined with anti-PD-L1. Mechanisms were investigated via single-cell RNA sequencing, flow cytometry, and in vivo/vitro functional assays. Clinical correlation was evaluated in patient-derived tumor fragments and a pilot clinical trial in ICC patients. LDGC combined with anti-PD-L1 treatment efficiently improved tumor immune microenvironment (TIME) through reducing immunosuppressive SPP1+ tumor-associated macrophages (TAMs) while promoting CD8⁺ T cell infiltration and cytotoxicity. LDGC reprograms the interplay between STAT1 and STAT3 transcriptional pathways in TAMs, thereby reducing SPP1 expression and weakening the inhibitory effect of the SPP1-VLA-4 signaling axis on CD8+ T cell, ultimately enhancing T cell cytotoxicity and sensitizing antitumor response to anti-PD-L1. Furthermore, the ICC patients exhibited superior response and tolerance to LDGC combined with immunotherapy.CONCLUSIONSThis study highlights that LDGC remodels the immunosuppressive microenvironment and potentiates anti-PD-L1 therapy, providing a rational regimen for ICC.
背景和目的虽然吉西他滨/顺铂联合抗pd - l1是晚期肝内胆管癌(ICC)的一线治疗方案,但疗效仍然有限,毒性显著,突出了优化治疗策略的必要性。我们试图研究低剂量GC (LDGC)是否可以释放抗pd - l1介导的抗肿瘤免疫,同时降低毒性。方法与结果采用多种临床前ICC小鼠模型,评估LDGC联合抗pd - l1的抗肿瘤疗效和毒性。通过单细胞RNA测序、流式细胞术和体内/体外功能测定来研究机制。临床相关性在患者来源的肿瘤碎片和在ICC患者的试点临床试验中进行了评估。LDGC联合抗pd - l1治疗通过减少免疫抑制性SPP1+肿瘤相关巨噬细胞(tam)有效改善肿瘤免疫微环境(TIME),同时促进CD8 + T细胞浸润和细胞毒性。LDGC重编程tam中STAT1和STAT3转录通路之间的相互作用,从而降低SPP1的表达,减弱SPP1- vla -4信号轴对CD8+ T细胞的抑制作用,最终增强T细胞的细胞毒性,增强抗pd - l1的抗肿瘤反应。此外,ICC患者对LDGC联合免疫治疗表现出更好的反应和耐受性。结论LDGC可重塑免疫抑制微环境,增强抗pd - l1治疗,为ICC提供合理的治疗方案。
