- Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related mortality worldwide, necessitating the identification of novel therapeutic targets. The transmembrane protein MAL2 has been implicated in various cancers, but its functional role and mechanistic underpinnings in HCC are not fully understood. To comprehensively understand its role in HCC, we analyze public single-cell RNA sequencing (scRNA-seq) data and find that MAL2 is significantly enriched in malignant HCC cells. , is stably knocked down by shRNA in Hep-3B and HCC-LM3 cell lines, and functional experiments including colony formation, EdU, transwell, and wound healing assays demonstrate that depletion markedly suppresses proliferation, invasion, and migration of HCC cell lines. , a subcutaneous tumor model using H22 cells reveals that knockdown inhibits tumor growth, accompanied by reduced Ki-67 level and increased apoptosis. Further analysis via mass cytometry indicates that MAL2 downregulation reshapes the immune microenvironment, notably reducing CD4 T cells, Tregs, CD8 T cells, and exhaustion markers (PD-L1, PD1, and TIGIT) while increasing B cells and myeloid-derived suppressor cells (MDSCs). Mechanistically, ELISA and immunofluorescence staining validate that knockdown impairs the secretion of CCL22, a chemokine known for recruiting Tregs, leading to reduced Treg recruitment and decreased production of the immunosuppressive cytokines IL-10 and TGF-β. In conclusion, MAL2 drives HCC progression by promoting tumor cell proliferation, invasion, and immunosuppression through CCL22-mediated Treg recruitment, positioning MAL2 as a promising therapeutic target to counteract tumor growth and remodel the immunosuppressive microenvironment in HCC. - Source: PubMed
Zhang QianSun XiaoweiZhang LantianNi TianyiWang YingyingTu LiyingYan WeiTang WeiweiWang Xuehao - Haemophilia A (HA) is an X-linked bleeding disorder caused by factor VIII (FVIII) deficiency, treated with FVIII infusions or, more recently, Emicizumab subcutaneously. Although Emicizumab is safe and effective, FVIII is still required for severe bleeding, trauma, or surgery, and few studies have compared these prophylactic options in paediatric patients. This study explores the immunological and haematological profiles of paediatric HA patients receiving FVIII or Emicizumab, using haemophilia B patients and healthy controls. Clinical parameters and immune cell populations showed no major differences aside from age-related variations. However, HA patients displayed higher HLA-DR expression on CD14 cells than healthy controls, and Emicizumab-treated patients showed increased HLA-DR expression on CD11c cells compared with FVIII-treated patients. Plasma cytokines including IL-12p40, TNF-α, CCL-22, IL-18, and CCL-4 were elevated in HA, suggesting a dysregulated myeloid compartment in HA. Patient-derived macrophages exhibited a stronger pro-inflammatory (M1-like) polarization after in vitro FVIII stimulation, with increased TNF-α and reduced TGF-β gene expression. Stratification by prophylaxis showed that macrophages from FVIII-treated patients maintained the M1 phenotype, whereas those from Emicizumab-treated patients showed no clear shift and tended toward an immune-regulatory profile. These findings highlight distinct myeloid and cytokine signatures associated with different prophylaxis, emphasizing the need for optimized therapeutic strategies. - Source: PubMed
Cottonaro AlessiaAkula SaicharanPollio BerardinoRicca IreneMartini TizianoAlbiani RobertoGiacchello Jacopo AgnelliSciancalepore PatriziaSanti RobertoFollenzi AntoniaMerlin Simone - Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality worldwide, increasingly driven by metabolic dysfunction-associated steatotic liver disease alongside viral and alcohol-related cirrhosis. The tolerogenic immune environment of the liver enables tumor immune escape, with regulatory T cells (Tregs) playing a central role. This review synthesizes human-focused evidence (tissues, blood, clinical cohorts, and single-cell/spatial studies) through September 2025 to define how Tregs are recruited, maintained, and functionally deployed in HCC. Across datasets, intratumoral effector-like Tregs (eTregs) expressing ICOS, CTLA-4, CCR8, and CD39/CD73 accumulate within tumors and co-localize with exhausted cytotoxic PD-1 CD8 T cells and suppressive myeloid cells. Recruitment is driven mainly by CCL20-CCR6 and CCL22/CCL17-CCR4 signaling, while CCR8 marks highly suppressive tumor-resident Tregs. Their persistence is supported by TGF-β, IL-10, IL-35, adenosine signaling, IL-2 sequestration, and metabolic adaptation. Spatial biomarkers, including ICOS/CCR8 eTreg density and CD8:Treg ratios, associate with prognosis and emerging immunotherapy responses. Etiology further shapes immune architecture: HBV-related HCC often forms Treg-exhausted T-cell niches around viral antigens, whereas MASLD/MASH promotes stromal and metabolic barriers that may reduce PD-(L)1 efficacy. Current treatments (PD-(L)1 blockade with anti-VEGF or CTLA-4, and some TKIs) intersect with Treg biology, while emerging strategies targeting CCR8, CCR4, ICOS, or the adenosine pathway aim to selectively disrupt intratumoral eTreg networks. This review underscores that an etiology-aware, spatial-biomarker framework may guide the integration of selective Treg targeting with PD-(L)1-based therapies in HCC. - Source: PubMed

Because few biomarkers reflect its underlying mechanisms, diagnosis at the initial visit is often difficult. Although steroid pulse therapy is widely used, approximately half of patients respond insufficiently. We therefore aimed to elucidate the immune mechanisms underlying AIGA and identify potential biomarkers for diagnosis and treatment response. - Source: PubMed

Takei ShingoHayashi RyotaOkamura ManonKatsumi TatsuyaKawai ToruAbe Riichiro - serovar Dublin ( Dublin) is a host-adapted pathogen that causes severe systemic disease in cattle and presents a zoonotic risk to humans. While macrophages play a pivotal role in host defense against they are also an intracellular niche for bacterial persistence. However, the mechanism underlying the early transcriptional response of macrophages to Dublin infection is poorly understood. This study used high-throughput sequencing to profile mRNA and miRNA expression in RAW 264.7 mouse macrophages 2 h after infection with Dublin compared to uninfected control cells. A total of 1,080 differentially expressed (DE) mRNAs were identified, of which 492 were up-regulated and 588 were down-regulated. In addition, 23 DE miRNAs, 18 up-regulated and 5 down-regulated, were identified. Meanwhile, KEGG enrichment analysis indicated significant enrichment of the DE mRNAs and miRNAs in signaling pathways associated with macrophage immune activation, including the TNF, HIF-1, and MAPK signaling pathways, as well as those involved in responses to infection. The accuracy of the mRNA sequencing results was verified using RT-qPCR. In conclusion, the findings showed significant up-regulation of , , , , and the early stages of Dublin infection of mouse macrophages, suggesting the involvement of these molecules in regulating the host immune response. - Source: PubMed
