摘要：T cell therapy has proven challenging for pancreatic ductal adenocarcinoma (PDAC), partly due to heterogeneous expression of tumor-associated antigens (TAAs). To address tumor heterogeneity and mitigate immune evasion, an ex vivo expanded, polyclonal, T helper 1 cell-polarized T cell product targeting five TAAs—PRAME, SSX2, MAGEA4, Survivin and NY-ESO-1—was developed. These antigens were chosen based on their tumor specificity, oncogenicity, immunogenicity and level of expression. In a phase 1/2 trial, this autologous nonengineered T cell product was administered (1?×?107 cells m?2 per infusion) monthly to patients with advanced PDAC responding (arm A, n?=?13) or refractory (arm B, n?=?12) to first-line chemotherapy or with resectable disease (arm C, n?=?12). Primary endpoints were safety and feasibility of completing six infusions, whereas exploratory efficacy endpoints included persistence and evaluating the relationship between clinical benefit and the expansion of the infused effector T cells, as well as the induction of de novo immune responses. Of 56 participants procured, 37 were infused, with only 1 treatment-related serious adverse event. Disease control rates in arms A and B were 84.6% (95% confidence interval: 54.6–98.1%) and 25% (95% confidence interval: 5.5–57.2%), respectively. In arm C, two of nine resected participants remained disease free after 66?months of follow-up. The infused cells persisted up to 12?months posttreatment and elevated levels of tumor-directed T cells were detected during dosing (P?=?0.027) and follow-up in responders compared to nonresponders. Clinical outcomes correlated with peripheral expansion of functional TAA-targeted T cell clones and treatment-emergent antigen spreading. Thus, further investigation of this approach, either as a single agent or combined with other complementary modalities, is warranted (ClinicalTrials.gov identifier: NCT03192462).

Hepatocellular carcinoma (HCC) is the most common primary liver carcinoma with high lethality. Both of hepatitis B virus (HBV) and Clonorchis sinensis (C. sinensis) are critical infectious contributors to HCC development. However, the inter-tumor heterogeneity and tumor microenvironment (TME) of HCC patients with different infectious background remain largely unknown.
We compiled a cohort of 269 primary HCC patients to assess the clinical impact of C. sinensis and HBV infections on patient prognosis. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomic (ST-seq) analyses were performed on tumor and adjacent normal samples from C. sinensis-associated HCC (CP), and double-infection HCC (DP) patients. Additionally, we integrated publicly available scRNA-seq and ST-seq datasets from HBV-associated (HP) patients. Immunofluorescence, immunohistochemistry and in vitro experiments were conducted to validate inter-tumor heterogeneity among the three HCC subtypes.
C. Sinensis infection is significantly associated with poorer prognosis in HCC patients. Multi-omics analyses revealed distinct inter-tumor heterogeneity in epithelial, immune, and stromal compartments across different HCC subtypes. Tumor cells in the DP group exhibited more malignant marker expression, higher copy number variation scores, increased activation of p53 pathway, and worse survival outcomes. Compared with other HCC subtypes, the TME in DP samples was enriched with SPP1+ macrophages, exhausted CD8+ T cells and COL1A1+ fibroblasts. In contrast, the CP and HP groups showed higher proportions of M2-like macrophages and ENPP2+ liver vascular endothelial cells, respectively.
These findings decipher the cellular signatures and their interactions within the TME, shedding light on the inter-tumoral heterogeneity driven by different infections, and the development of targeted therapies for infectious HCC.

摘要：Glycolysis and mitochondrial fatty acid oxidation (FAO) regulate CD8+ T cell differentiation, but how this metabolic balance regulates T cell exhaustion is unclear. PD-1 signaling inhibits glycolysis and enhances FAO. Here, we show that CD8+ T cells in tumors adhere to glycolysis with attenuated FAO despite high PD-1 expression. Active aldehydes, final products of lipid peroxidation, accumulate in CD8+ T cells in proportion to their level of exhaustion, defined by mitochondrial mass and potential. Aldehydes promote glycolysis and inhibit FAO in T cells. Mice deficient in an FAO enzyme in T cells generate more acrolein, a representative aldehyde, enhancing T cell exhaustion and attenuating antitumor immunity. Acrolein is generated partly from mitochondria and damages mitochondrial architecture. Inhibitors of lipid peroxidation or aldehydes enhanced PD-1-blockade by rectifying metabolic imbalance. Therefore, active aldehydes resulting from FAO impairment can cause a vicious cycle of metabolic imbalance that leads to T cell exhaustion.

摘要：Treatment-refractory rheumatoid arthritis (RA) is a major unmet need, and the underlying mechanisms are poorly understood. To identify molecular determinants of refractory RA, we performed spatial transcriptomic profiling on synovial tissue biopsy samples taken 6 months before and after treatment. In the baseline biopsy samples of non-remitting patients, we identified increased fibrogenic signaling within vascular tissue niches, marked by high fibroblast COMP expression. We uncovered a role of endothelial-derived Notch signaling as an upstream regulator of fibroblast transforming growth factor beta (TGFβ) signaling via its opposing ability to induce TGFβ isoform expression while suppressing TGFβ receptors, generating a proximal-to-distal gradient of TGFβ sensitivity that can be altered with disruption of steady-state Notch signaling. In posttreatment biopsy samples, we observed significant immune depletion with expansion of fibrogenic niches, a process that can be reversed by inhibition of Notch and TGFβ signaling in RA patient-derived organoids. Collectively, our data implicate targeting of TGFβ signaling to prevent exuberant synovial tissue fibrosis as a potential therapeutic strategy for refractory RA.

摘要：Metabolic dysfunction-associated steatohepatitis (MASH) is an important phase in the progression of metabolic dysfunction-associated steatotic liver disease to end-stage liver diseases, posing an increasing threat to public health worldwide with limited treatment options. Here we show that GPR110 is a liver-selective G-protein-coupled receptor closely associated with MASH in a sex-specific manner. Hepatocyte-specific Gpr110 knockout protects against MASH in female, but not male mice. The GPR110 variant rs937057 T?>?C is associated with a higher prevalence of metabolic dysfunction-associated steatotic liver disease in women. The improved liver phenotypes in female mice are abrogated by knocking down the expression of hepatic oestrogen receptor alpha (Esr1). Mechanistically, GPR110 couples to Gαs and activates protein kinase A, thereby inducing phosphorylation of NFAT2, which inhibits its nuclear translocation and transcriptional activity, leading to suppressed Esr1 transcription in hepatocytes. Taken together, these results demonstrate a sex-specific role of GPR110 in MASH by regulating hepatic oestrogen sensitivity, suggesting inhibition of GPR110 as a potential sex-specific therapy for MASH.

摘要：Osteoarthritis (OA) remains a debilitating joint disorder due to the lack of disease-modifying therapies that can simultaneously halt cartilage degradation and modulate the aberrant immune microenvironment. This study demonstrated the therapeutic potential of extracellular vesicles derived from adipose-derived stem cells preconditioned with nanosecond pulsed electric fields (NsPEFs-ADSCs-EVs). Administration of NsPEFs-ADSCs-EVs significantly attenuated OA progression, as indicated by alleviated cartilage degradation, and a marked shift in synovial macrophage from the pro-inflammatory M1 to the pro-reparative M2 phenotype. Mechanistically, we discovered that NsPEFs-ADSCs-EVs, via surface-enriched ITGA4, activated the PI3K/Akt pathway to instruct the increased secretion of R-spondin 3 (RSPO3). We further unveiled a novel dual function of chondrocyte-derived RSPO3. It acted in an autocrine manner to enhance chondrocyte anabolism and in a paracrine manner to directly drive M2 macrophage polarization. The pro-M2 effect was specifically mediated through the activation of the LGR4/LRP6/β-catenin signaling axis in macrophages. Collectively, this work elucidates a previously unrecognized paracrine axis wherein NsPEFs-engineered EVs deploy RSPO3 as a significant coordinator to synchronously promote cartilage regeneration and immune resolution. Our findings not only reveal RSPO3 as a promising therapeutic target but also establish the NsPEFs platform as a efficient strategy for generating functionally enhanced EVs, offering a novel cell-free strategy for OA therapy.

摘要：Cardiac aging is a major driver of cardiovascular diseases and associated mortality, yet its therapeutic options are limited. While long interspersed nuclear element-1 (LINE-1) retrotransposons are known to drive cellular senescence, their role in cardiac aging is poorly defined. Here we showed that LINE-1 expression increased in the heart with age. To investigate their role in cardiac aging, we generated cardiomyocyte-specific Mov10-knockout mice, which failed to suppress LINE-1. These mice developed LINE-1 derepression, cardiac dysfunction and premature cardiac aging by 3 months of age, accompanied by cGAS–STING activation. Pharmacological inhibition of LINE-1 reverse transcription (with 3TC) or STING (with H-151) suppressed cGAS–STING activation and attenuated senescence in Mov10-knockout H9C2 cells. Notably, both inhibitors improved cardiac function and reduced cardiac inflammation and senescence phenotypes in naturally aged mice. Together, our findings establish LINE-1 as a driver of cardiac aging via cGAS–STING activation, highlighting LINE-1 and its downstream effectors as therapeutic targets for age-related cardiac dysfunction.

摘要：Osteochondral defects involving articular cartilage and subchondral bone remain clinically challenging due to limited regenerative capacity and the suboptimal outcomes of current therapies. Recent studies underscore the critical role of the immune microenvironment, particularly macrophage polarization, in modulating chondrogenic and osteogenic differentiation, whereas dysregulated inflammation leads to fibrocartilage formation and impaired tissue regeneration. To address these challenges, we developed a UV-triggered injectable dual-network hydrogel, representing the first application of Bletilla striata polysaccharide (BSP) in osteochondral repair. By combining methacrylamide-modified BSP (BSPMA) with nitrobenzaldehyde-functionalized hyaluronic acid (HANB), the dual-network hydrogel integrates immunomodulatory capacity, mechanical robustness, and tissue integration. BSPMA targets macrophage mannose receptors, suppressing pro-inflammatory M1 polarization and promoting M2 phenotypes to establish a regenerative immune niche. Simultaneously, HANB forms dynamic Schiff base bonds with host tissue, enhancing interfacial integration and reducing secondary damage. This dual-network strategy overcomes the mechanical and adhesive limitations of conventional BSP-based systems, offering a promising platform for osteochondral tissue regeneration.

摘要：Ultraviolet irradiation, particularly ultraviolet B (UVB), damages keratinocytes, potentially causing actinic cheilitis. Commensal bacteria help maintain barrier function and protect the host. However, it is unclear if commensal bacteria can protect the host from UVB irradiation. Here, we demonstrate that Rothia mucilaginosa (R. mucilaginosa)-derived membrane vesicles (RMVs) contain ferrochelatase, which stabilizes labile iron in host cells to alleviate UVB-induced ferroptosis. We demonstrate that R. mucilaginosa abundance on lip vermilion inversely correlates with actinic cheilitis severity in patients. Mechanistically, we find that UVB induces R. mucilaginosa to release RMVs, which are internalized by host cell lysosomes. The ferrochelatase contained within these RMVs catalyzes conversion of Fe2+ and porphyrin into heme, thereby alleviating UVB-induced iron overload and ferroptosis. Topical application of RMVs relieves actinic cheilitis in patients (ChiCTR, no. ChiCTR2500100015). Collectively, we reveal an iron stabilization mechanism through which commensal bacteria protect the host against UVB and expand our understanding of the relationship between commensal bacteria and hosts.
