Pancreatic ductal adenocarcinoma (PDAC) is characterized by perineural invasion and modulated by autonomic (sympathetic and parasympathetic) and sensory innervations. Here, we further demonstrated that within the tumor microenvironment of PDAC, nociceptor neurons interacted with cancer-associated fibroblasts (CAFs) through calcitonin gene-related peptide (CGRP) and nerve growth factor (NGF). This interaction led to the inhibition of interleukin-15 expression in CAFs, suppressing the infiltration and cytotoxic function of natural killer (NK) cells and thereby promoting PDAC progression and cancer pain. In PDAC patients, nociceptive innervation of tumor tissue is negatively correlated with the infiltration of NK cells while positively correlated with pain intensity. This association serves as an independent prognostic factor for both overall survival and relapse-free survival for PDAC patients. Our findings highlight the crucial regulation of NK cells by nociceptor neurons through interaction with CAFs in the development of PDAC. We also propose that targeting nociceptor neurons or CGRP signaling may offer a promising therapy for PDAC and cancer pain.","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"35 5","pages":"362-380"},"PeriodicalIF":25.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143677992","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}

However, its detailed mechanisms remain poorly understood. In this study, we investigated the SPARDA system from Novosphingopyxis baekryungensis (NbaSPARDA) and discovered an unexpected filament configuration upon target DNA binding, which strongly correlated with collateral nuclease activity. Filament formation and nuclease activation require a guide–target heteroduplex of sufficient length with perfect complementarity at the central region. A series of cryo-EM structures of NbaSPARDA complexes, loaded with guide RNA, target DNA of varying lengths, and substrate ssDNA, were determined at ~3.0 Å resolution. Structural analyses indicated that guide RNA binding induces dimerization of the NbaSPARDA complex, while target DNA engagement disrupts this dimerization. Further propagation of the guide–target heteroduplex triggers filament formation through a checkpoint mechanism. The NbaSPARDA filament consists of a backbone formed by interlocking short Argonaute proteins, with an inner layer composed of DREN nuclease domains. Filament formation leads to tetramerization of the monomeric DREN nuclease domain, activating its collateral nuclease activity against environmental nucleic acids — a feature leveraged for molecular diagnostics. For bacteria heterologously expressing the NbaSPARDA system, defense against invading bacteriophages and plasmids relies on filament formation. Collectively, these findings illustrate the detailed working mechanism of the NbaSPARDA complex and highlight the importance of its filament formation in host defense.","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"35 7","pages":"510-519"},"PeriodicalIF":25.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41422-025-01100-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678022","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}

Although structures of GPCRs in complex with G protein or GRK in a BAM-bound state have recently been resolved, revealing that BAM can induce biased signaling by directly modulating interactions between GPCRs and these two transducers, no BAM-bound GPCR–arrestin complex structure has yet been determined, limiting our understanding of the full pharmacological profile of BAMs. Herein, we developed a chemical protein synthesis strategy to generate neurotensin receptor 1 (NTSR1) with defined hexa-phosphorylation at its C-terminus and resolved high-resolution cryo-EM structures (2.65–2.88 Å) of NTSR1 in complex with both β-arrestin1 and the BAM SBI-553. These structures revealed a unique “loop engagement” configuration of β-arrestin1 coupling to NTSR1 in the presence of SBI-553, markedly different from the typical “core engagement” configuration observed in the absence of BAMs. This configuration is characterized by the engagement of the intracellular loop 3 of NTSR1 with a cavity in the central crest of β-arrestin1, representing a previously unobserved, arrestin-selective conformation of GPCR. Our findings fill the critical knowledge gap regarding the regulation of GPCR–arrestin interactions and biased signaling by BAMs, which would advance the development of safer and more efficacious GPCR-targeted therapeutics.","PeriodicalId":9926,"journal":{"name":"Cell Research","volume":"35 4","pages":"284-295"},"PeriodicalIF":28.1,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41422-025-01095-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672367","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}
