Hyaluronic acid and tissue mechanics orchestrate mammalian digit tip regeneration

Tissue regeneration is rare in mammals, but the digit tip can regrow after amputation, whereas injuries beyond the nail do not. We found that the ECM and tissue mechanics govern the amputation response. Nonregenerative regions were stiffer and contained dense, organized collagen, whereas regenerative regions were soft and enriched in hyaluronic acid (HA). Depleting HA inhibited regeneration and promoted fibrosis. Stabilization of HA with HAPLN1 after nonregenerative amputations tuned ECM mechanics, reduced scarring, and enhanced bone repair. ECM-targeted strategies could help unlock mammalian regeneration.

CAR-M2免疫治疗通过促进再血管化并诱导促纤维化Cxcr2+内皮细胞凋亡缓解肾纤维化

CAR-M2 immunotherapy resolves renal fibrosis via revascularization and apoptosis of profibrotic Cxcr2+ endothelial cells

Renal fibrosis is a common outcome of chronic kidney disease (CKD), forming a fibrotic niche characterized by fibroblast activation and vascular rarefaction. Currently, there are no effective treatment strategies targeting fibrotic niche. Here, we show that chimeric antigen receptor-modified M2 macrophages (CAR-M2) targeting FAP and secreting interleukin (IL)-4 are delivered via an injectable HAMA-CS hydrogel beneath the renal subcapsule and attenuate renal fibrosis while promoting renal revascularization. The single-cell RNA sequencing reveals the heterogeneity and interaction of stroma and endothelial cells (ECs). A fibrosis-related Cxcr2+ EC subset is identified, and its specific depletion effectively mitigates renal fibrosis. Further results reveal that CAR-M2 can release matrix metalloproteinase 2 (MMP2) in close proximity to activate retinoid X receptor alpha (Rxra) in the Cxcr2+ ECs and further triggers its mitochondrial autophagy, leading to apoptosis. Our research provides innovative strategies and proof of principle for the immunotherapy of organ fibrosis.

The skin microbiota drives cutaneous immune checkpoint inhibitor toxicity in genetically susceptible mice

Immune checkpoint inhibitors (ICIs) show increasing promise for cancer therapy. However, patients can experience adverse events, particularly those with pre-existing autoimmune disease. We determined that the microbiome can drive ICI-induced systemic toxicity in a mouse model of autoimmune susceptibility. Specifically, ICI treatment of specific pathogen-free (SPF) Act1-/- mice, which develop spontaneous autoimmunity due to a deficiency in an immune adaptor, resulted in systemic adverse events that were ameliorated by topical antibiotics. Moreover, germ-free (GF) Act1-/- mice failed to develop ICI toxicity. Transfer of gut or skin microbiota from SPF Act1-/- mice to GF Act1-/- mice showed that only the skin microbiota rendered exGF mice sensitive to ICI toxicity. Notably, therapeutic application of topical antibiotics decoupled ICI-induced toxicity from anti-tumor efficacy in SPF Act1-/- mice. This model provides a paradigm for future translational studies in cancer patients to mitigate adverse effects of ICIs and maximize their efficacy by targeting skin microbes.

Peritumoural adipose tissue promotes ferroptosis resistance by 3-hydroxykynurenine-mediated suppression of ferritinophagy - Nature Cell Biology

The peritumoural adipose tissue (PAT) is a key contributor to cancer therapy resistance, yet its role in regulating ferroptosis remains unclear. Here we demonstrate that PAT confers ferroptosis resistance to cancer cells by upregulating ferritin (FTH1/FTL) and sequestering intracellular iron. PAT-derived kynurenine (KYN) was identified as the principal mediator. KYN is taken up by cancer cells and metabolized to 3-hydroxykynurenine, which directly binds to nuclear receptor coactivator 4 (NCOA4). This interaction inhibits NCOA4-mediated ferritinophagy, preventing ferritin degradation and limiting the free iron pool required for ferroptosis. In murine models, pharmacological inhibition of the KYN pathway synergized with PD-1 blockade to overcome ferroptosis resistance and suppress tumour progression. These findings reveal a PAT–KYN–ferritinophagy axis that promotes ferroptosis resistance, highlighting the potential of targeting adipose–tumour cross-talk to enhance immunotherapy in PAT-associated tumours. Zhang, Han, Tan, Lu, Ma et al. report that kynurenine derived from peritumoural adipose tissue is hijacked by cancer cells to mediate ferroptosis resistance, a process that could potentially be targeted with immunotherapy to inhibit tumour growth.

GREM1 通过 LEPR 阳性骨骼细胞介导植入周纤维化

GREM1 acts in leptin receptor-expressing skeletal cells to mediate peri-implant fibrosis - Nature Communications

Globally, approximately 1.3 million total joint implants are placed annually, and around 80,000 patients develop aseptic loosening, a leading cause of implant failure driven by peri-implant fibrosis. Here, we show that the BMP-antagonist Gremlin-1 (GREM1), expressed by leptin receptor–expressing skeletal (LEPR+) cells, is a key regulator of this process. GREM1 is highly expressed by LEPR+ cells in peri-implant fibrotic tissue in mice and humans. Conditional deletion of Grem1 in LEPR+ cells attenuate peri-implant fibrosis and enhances peri-implant osteogenesis. Transcriptomic and functional analyses show that loss of Grem1 in LEPR+ cells upregulate the bone morphogenetic protein (BMP) and WNT pathways, increasing in vivo osteogenesis and reducing fibrous tissue formation. As proof-of-concept, intra-articular administration of a neutralizing antibody against GREM1 (anti-GREM1) in mice prevents and reverses peri-implant fibrous tissue while promoting peri-implant bone formation. Inhibition of GREM1 in LEPR+ cells therefore represent a promising strategy to prevent and treat aseptic loosening.

腱周感觉神经中 YAP1/pSTAT3/NRP1 轴的激活促进肌腱愈合

Activation of the YAP1/pSTAT3/NRP1 axis in peritendinous sensory nerves promotes tendon healing

Chemotactic migration of peritendinous nerves is essential for tendon regeneration, yet the underlying neuroelectrical mechanisms remain unclear. Here, we identify an electrically responsive yes-associated protein 1 (YAP1)/phosphorylated signal transducer and activator of transcription 3 (pSTAT3)/neuropilin-1 (NRP1) signaling axis in sensory neurons. Electrical stimulation enhances YAP1-pSTAT3 interaction, promotes pSTAT3 nuclear translocation and transcriptional activity, and up-regulates NRP1 to support growth of calcitonin gene-related peptide (CGRP)–positive sensory fibers. Guided by these findings, we engineered a bifunctional piezoelectric patch composed of poly(vinylidene difluoride-trifluoroethylene) [P(VDF-TrFE)] and regenerated silk fibroin@poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (RSF@P:P), coupling mechanically induced electrical cues with dynamic lubrication. Under ultrasound activation, the P(VDF-TrFE) layer generates localized electrical signals that facilitate sensory-nerve and vascular ingrowth, while the RSF@P:P layer undergoes piezoelectric-triggered gel-sol transition to form a low-friction interface and reduce adhesion. In rat and Bama minipig models, the patch markedly enhanced tendon regeneration and decreased adhesion scores by ~50%. These findings establish a neuroelectrically guided strategy for enhancing tendon healing.

Reciprocal regulation of fibroblast–macrophage equilibrium governs skin integrity

Fibroblast-macrophage crosstalk is well-established in vitro, and fibroblast-derived colony-stimulating factor 1 (CSF1) supports macrophages in select tissues. However, whether macrophages regulate fibroblasts in vivo remains unknown. Leveraging genetic mouse models, single-cell multi-omics, flow cytometry and imaging, we show that fibroblast depletion or loss of fibroblast-derived growth factors impacts skin macrophage populations in the dermis and hypodermis. Conditional deletion of Csf1 in Dpt+ fibroblasts progressively decreases CD64+ and CD11c+ macrophages, impairing skin wound healing. Reduced macrophage abundance disrupts fibroblast cell cycle regulation, metabolism and immune signaling, and increases fibroblast abundance, affirming a reciprocal relationship. In human systemic sclerosis (scleroderma), elevated fibroblast-derived CSF1 and increased macrophage abundance correlate with disease severity, implicating the CSF1-CSF1R axis in pathology. These findings provide in vivo evidence of macrophage regulation of fibroblasts, revealing a bidirectional interplay that advances understanding of tissue homeostasis and immune regulation in skin.

Lactate derived from macrophages drives skin dermal fibroblasts phenotypic remodeling via MCT1-primed histone H3 lysine 23 lactylation in hypertrophic scar - Nature Communications

Hypertrophic scar (HS) is a fibroproliferative disorder characterized by fibroblast hyperactivation and aberrant extracellular matrix deposition. This study identifies macrophage-derived lactate as a key mediator of fibroblast phenotypic remodeling via monocarboxylate transporter 1 (MCT1)-mediated histone H3 lysine 23 lactylation (H3K23la) in HS. Elevated lactate levels and MCT1 expression were observed in HS tissues, with macrophages in stiff mechanical microenvironments identified as the primary lactate source. Lactate influx through MCT1 upregulated H3K23la, thereby promoting transcriptional activation of profibrotic genes HEY2 and COL11A1. Mechanistically, HEY2 activated YAP1/SMAD2 signaling, while COL11A1 stabilized MCT1 to enhance lactate transport, forming a positive loop that amplified fibrosis. Fibroblast-specific Mct1 deletion or pharmacological inhibition of Mct1 in male mice reduced collagen deposition, accelerated wound healing, and attenuated scar formation. Our findings redefine the macrophage-fibroblast crosstalk in HS and establish the MCT1-H3K23la-HEY2/COL11A1 axis, particularly its self-reinforcing loop, as a novel therapeutic target. The study identified macrophage-derived lactate as a driver of hypertrophic scar. Lactate influx via MCT1 triggers histone lactylation in fibroblasts to activate profibrotic genes.

Metabolic support protects mucosa from ferroptosis in radiation-induced mucositis

Ionizing radiation is effective in treating cancer but causes significant damage to the mucosa, thereby increasing patient discomfort, delaying therapy, and raising the risk of mortality. The underlying mechanisms of this damage remain poorly understood, and current treatments are largely palliative. In this study, ferroptosis was identified as the primary mode of cell death responsible for the radiation-induced depletion of oral mucosal epithelial cells. Notably, a compensatory phase was also discovered in the early stages following radiation exposure, during which fibroblasts provide crucial metabolic support. Specifically, fibroblasts supply polyamines that are readily absorbed by basal epithelial cells, protecting them from ferroptosis. Supplementation with polyamines was found to effectively prevent mucosal injury. These findings highlight the critical role of fibroblast-mediated metabolic support in protecting the oral mucosa from radiation-induced damage and offer insights into enhancing the body's intrinsic protective mechanisms against radiation-related diseases.

A single-cell and spatial genomics atlas of human skin fibroblasts reveals shared disease-related fibroblast subtypes across tissues

Fibroblasts sculpt the architecture and cellular microenvironments of various tissues. Here we constructed a spatially resolved atlas of human skin fibroblasts from healthy skin and 23 skin diseases, with comparison to 14 cross-tissue diseases. We define six major skin fibroblast subtypes in health and three that are disease-specific. We characterize two fibroblast subtypes further as they are conserved across tissues and are immune-related. The first, F3: fibroblastic reticular cell-like fibroblast (CCL19+CD74+HLA-DRA+), is a fibroblastic reticular cell-like subtype that is predicted to maintain the superficial perivascular immune niche. The second, F6: inflammatory myofibroblasts (IL11+MMP1+CXCL8+IL7R+), characterizes early human skin wounds, inflammatory diseases with scarring risk and cancer. F6: inflammatory myofibroblasts were predicted to recruit neutrophils, monocytes and B cells across multiple human tissues. Our study provides a harmonized nomenclature for skin fibroblasts in health and disease, contextualized with cross-tissue findings and clinical skin disease profiles.

骨桥蛋白减轻硅胶植入物的异物反应

Osteopontin attenuates the foreign-body response to silicone implants

Silicone implants are widely used in plastic and reconstructive surgery, but their efficacy is limited by the foreign-body response (FBR), which causes capsular contracture, implant failure, and secondary surgeries. Acellular dermal matrices (ADMs) reduce the FBR clinically, but the molecular mechanism is unclear. Here we show that osteopontin (SPP1) secreted by monocyte/macrophage clusters adjacent to the ADM is both necessary and sufficient to attenuate the FBR to silicone implants, and that SPP1 acts via CD44 receptor signalling and upregulation of matrix metalloproteinase 9. Sustained local delivery of SPP1 via injectable, self-healing polymer-nanoparticle hydrogels phenocopies the protective effect of ADMs in both immunocompetent and SPP1-knockout mice, suggesting a potential strategy to mitigate the FBR without the need for ADMs.

Prevention and treatment of peri-implant fibrosis by functionally inhibiting skeletal cells expressing the leptin receptor - Nature Biomedical Engineering

The cellular and molecular mediators of peri-implant fibrosis—a most common reason for implant failure and for surgical revision after the replacement of a prosthetic joint—remain unclear. Here we show that peri-implant fibrotic tissue in mice and humans is largely composed of a specific population of skeletal cells expressing the leptin receptor (LEPR) and that these cells are necessary and sufficient to generate and maintain peri-implant fibrotic tissue. In a mouse model of tibial implantation and osseointegration that mimics partial knee arthroplasty, genetic ablation of LEPR+ cells prevented peri-implant fibrosis and the implantation of LEPR+ cells from peri-implant fibrotic tissue was sufficient to induce fibrosis in secondary hosts. Conditional deletion of the adhesion G-protein-coupled receptor F5 (ADGRF5) in LEPR+ cells attenuated peri-implant fibrosis while augmenting peri-implant bone formation, and ADGRF5 inhibition by the intra-articular or systemic administration of neutralizing anti-ADGRF5 in the mice prevented and reversed peri-implant fibrosis. Pharmaceutical agents that inhibit the ADGRF5 pathway in LEPR+ cells may be used to prevent and treat peri-implant fibrosis.

Multi-omics single-cell data integration and regulatory inference with graph-linked embedding

Despite the emergence of experimental methods for simultaneous measurement of multiple omics modalities in single cells, most single-cell datasets include only one modality. A major obstacle in integrating omics data from multiple modalities is that different omics layers typically have distinct feature spaces. Here, we propose a computational framework called GLUE (graph-linked unified embedding), which bridges the gap by modeling regulatory interactions across omics layers explicitly. Systematic benchmarking demonstrated that GLUE is more accurate, robust and scalable than state-of-the-art tools for heterogeneous single-cell multi-omics data. We applied GLUE to various challenging tasks, including triple-omics integration, integrative regulatory inference and multi-omics human cell atlas construction over millions of cells, where GLUE was able to correct previous annotations. GLUE features a modular design that can be flexibly extended and enhanced for new analysis tasks. The full package is available online at https://github.com/gao-lab/GLUE.
