Necroptosis is a form of regulated necrosis associated with different diseases. Here, we reported the identification of the first functional soluble tissue factor (sTF) in mediating blood coagulation, shed from the membrane full-length TF (flTF) by proteases, ADAMs, during necroptosis. By generating sTF-specific antibody and transgenic mice carrying knockin mutations at the ADAM cleavage site of TF (T211V212 mutated to E211E212), we demonstrated that this sTF is responsible for necroptosis-related thrombosis in inflammation and viral infection mouse models. Importantly, we showed that eliminating necroptosis or the cleavage of the flTF blocked the production of sTF and prevented thrombosis in mice. We also detected sTF in the plasma of human COVID-19 patients and showed that SARS-CoV-2 pseudovirus induced sTF production.

Here, we demonstrate that endosome-localized self RNA Rmrp directly binds to TLR3 and induces TLR3 dimerization in the early endosome but does not interact with endosome-localized TLR7, TLR8, TLR9 or cytoplasmic RNA sensor RIG-I under homeostatic conditions. Cryo-EM structure of Rmrp-TLR3 complex reveals a novel lapped conformation of TLR3 dimer engaged by Rmrp, which is distinct from the activation mechanism by dsRNA and the specific structural feature at the 3'-end of Rmrp is critical for its functional interaction with TLR3. Furthermore, K42 residue of TLR3 is essential for binding to Rmrp and subsequent dimerization. Rmrp dissociates from TLR3 following endosomal acidification, generating a matured TLR3 dimer which is primed for innate recognition and activation. Myeloid-cell deficiency of Rmrp reduces TLR3 dimerization and attenuates TLR3-mediated antiviral responses against influenza A both in vitro and in vivo. These findings elucidate the structural mode of self RNA Rmrp-primed TLR3 dimerization and ready for efficient innate recognition on endosomal membrane, extending our knowledge of how membrane-associated TLRs pre-dimerize and suggesting a new function of subcellular localized self RNAs in empowering innate activation.","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"11 1","pages":""},"PeriodicalIF":44.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Syngeneic mouse tumor models are critical for understanding tumor immune evasion and testing cancer immunotherapy. Derived from established mouse tumor cell lines that can already evade the immune system, these models cannot simulate early phases of immunoediting during initial tumorigenesis. We developed a syngeneic mouse teratoma model derived from noncancerous mouse embryonic stem cells and conducted a genome-wide CRISPR screen to identify genes that impact early phases of cancer immunoediting. We found that loss of pro-apoptotic tumor suppressor genes, including <i>Trp53</i>, increased necrosis in teratomas, releasing APOE lipid particles into the extracellular milieu. Infiltrating T cells drawn to tumor necrotic regions accumulated lipids and became dysfunctional. Blocking lipid uptake in T cells or reducing necrosis in teratomas by inactivating the mitochondrial permeability transition pore (mPTP) restored immunosurveillance. Because mouse teratomas were highly enriched for brain tissues, we next examined the tumor-immune interaction in human glioblastoma (GBM). Indeed, infiltrating T cells in TP53-mutated human GBM accumulated APOE and were dysfunctional. Anti-APOE and anti-PDCD1 antibodies synergistically boosted anti-GBM immunity and prolonged survival in mice. Our results link mPTP-mediated tumor necrosis to immune evasion and suggest that targeting the uptake of lipids released by necrotic tumor cells by infiltrating immune cells can enhance cancer immunotherapy.</p>","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"2 1","pages":""},"PeriodicalIF":44.1,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144930208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using proteomic and phosphoproteomic analyses of the bilateral striatum — a hub for important brain functions and a common node of autism pathophysiology — we identified significant phosphorylation asymmetries. Particularly,&nbsp;the phosphorylation processes&nbsp;in the left striatum appear more prone to disturbance. Notably, SH3RF2, whose single-copy knockout leads to autism spectrum disorder (ASD)-like behaviors in mice, is uniquely expressed in the striatum, forming a complex with CaMKII (an ASD-associated protein) and PPP1CC. Loss of SH3RF2 disturbs the CaMKII/PP1 “switch”, resulting in hyperactivity of CaMKII and increased phosphorylation of its substrate GluR1. In Sh3rf2-deficient mice, heightened GluR1-Ser831 phosphorylation and its aberrant postsynaptic membrane localization in the left striatum may impair the functional lateralization of striatal neurons and contribute to autism-like behaviors. This study unveils the first molecular mechanism governing brain lateralization in mammals, linking its impairment to autism development and treatment strategies.","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"35 10","pages":"762-774"},"PeriodicalIF":25.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41422-025-01174-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144928211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This post-translational modification of glutamate residues is catalyzed by the membrane-embedded vitamin K-dependent γ-carboxylase (VKGC), which typically recognizes protein substrates through their tightly bound propeptide that triggers γ-carboxylation. However, the osteocalcin propeptide exhibits negligible affinity for VKGC. To understand the underlying molecular mechanism, we determined the cryo-electron microscopy structures of VKGC with osteocalcin carrying a native propeptide or a high-affinity variant at different carboxylation states. The structures reveal a large chamber in VKGC that maintains uncarboxylated and partially carboxylated osteocalcin in partially unfolded conformations, allowing their glutamate-rich region and C-terminal helices to engage with VKGC at multiple sites. Binding of this mature region together with the low-affinity propeptide effectively stimulates VKGC activity, similar to high-affinity propeptides that differ only in closely fitting interactions. However, the low-affinity propeptide renders osteocalcin prone to undercarboxylation at low vitamin K levels, thereby serving as a discernible biomarker. Overall, our studies reveal the unique interaction of osteocalcin with VKGC and provide a framework for designing therapeutic strategies targeting osteocalcin-related bone and metabolic disorders.","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"35 10","pages":"735-749"},"PeriodicalIF":25.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144928541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
