Lipopolysaccharides found in gram-negative microbes have a terminal lipid A in their outer membrane. Here, we report that structural variations in symbiotic lipid A lead to divergent immune responses with each lipid A structure, eliciting effects distinct from those induced by classical lipid A. Certain lipid A structures can induce a sustained interferon (IFN)-β response orchestrated by Cdc42-facilitated Toll-like receptor 4 (TLR4) endocytosis and lipid droplet (LD) formation. This lipid A-directed IFN-β response is paramount for colon RORγt<sup>+</sup> regulatory T cell (Treg) induction while simultaneously suppressing colonic T<sub>H</sub>17 cells and controlling gut inflammation. Intriguingly, the quantitatively dominant penta-acylated lipid A species in Bacteroidetes fails to elicit an IFN-β response. Instead, a less abundant tetra-acylated lipid A species sustainably induces IFN-β, thereby contributing to RORγt<sup>+</sup> Treg homeostasis. Nuances in symbiont lipid A structure contribute to maintaining potent regulation of Tregs to maintain a healthy endobiotic balance.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"52 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677398","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}

To overcome this limitation, we developed SPIDR (split-and-pool identification of RBP targets), a highly multiplexed split-pool method that profiles the binding sites of dozens of RBPs simultaneously. SPIDR identifies precise, single-nucleotide binding sites for diverse classes of RBPs. Using SPIDR, we uncovered an interaction between LARP1 and the 18S rRNA and resolved this interaction to the mRNA entry channel of the 40S ribosome using cryoelectron microscopy (cryo-EM), providing a potential mechanistic explanation for LARP1’s role in translational suppression. We explored changes in RBP binding upon mTOR inhibition and identified that 4EBP1 preferentially associates with translationally repressed mRNAs upon mTOR inhibition.

To address this, we introduced a cell-type-specific, multi-target drug discovery strategy grounded in human data and real-world evidence. This approach integrates single-cell transcriptomics, drug perturbation databases, and clinical records. Using this framework, letrozole and irinotecan were identified as a potential combination therapy, each targeting AD-related gene expression changes in neurons and glial cells, respectively. In an AD mouse model with both Aβ and tau deposits, this combination therapy significantly improved memory performance and reduced AD-related pathologies compared with vehicle and single-drug treatments. Single-nucleus transcriptomic analysis confirmed that the therapy reversed disease-associated gene networks in a cell-type-specific manner. These results highlight the promise of cell-type-directed combination therapies in addressing multifactorial diseases like AD and lay the groundwork for precision medicine tailored to patient-specific transcriptomic and clinical profiles.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"29 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669960","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}

Mutations in MCT8 result in Allan-Herndon-Dudley syndrome (AHDS), an X-linked birth defect characterized by neurodevelopmental impairments and peripheral hyperthyroidism, whereas OATP1C1 deficiency is linked to brain hypometabolism and progressive neurodegeneration. Here, we report cryoelectron microscopy (cryo-EM) structures of MCT8 and OATP1C1 bound with the active thyroid hormone triiodothyronine (T3) and the prohormone thyroxine (T4) at 2.9 and 2.3 Å resolutions, respectively. Combined with functional studies, we elucidate their distinct thyroid hormone recognition and transport mechanisms and explain disease mutations. Although extracellular allosteric sites are not a common feature of SLC transporters, we identify one in OATP1C1.
