摘要:Nonsense mutations are associated with numerous and diverse pathologies, yet effective treatment strategies remain elusive. A promising approach to combat these conditions involves the use of aminoglycosides, particularly in combination with stop-codon read-through enhancers, for developing drugs that can rescue the production of full-length proteins. Using X-ray crystallography and single-particle cryo-EM, we obtained structures of the eukaryotic ribosome in complexes with several aminoglycos...

摘要:Argonaute (AGO) proteins bind to small RNAs to induce RNA interference (RNAi), a conserved gene regulatory mechanism in animal, plant, and fungal kingdoms. Small RNAs of the fungal plant pathogen Botrytis cinerea were previously shown to translocate into plant cells and to bind to the host AGO, which induced cross-kingdom RNAi to promote infection. However, the role of pathogen AGOs during host infection stayed elusive. In this study, we revealed that members of fungal plant pathogen B. cinere...

摘要:Plasmid conjugation is a contact-dependent horizontal gene transfer mechanism that significantly contributes to the dissemination of antibiotic resistance among bacteria. While the molecular mechanisms of conjugation have been extensively studied, our understanding of plasmid transfer dynamics within spatially structured bacterial communities and the influence of community architecture on plasmid dissemination remains limited. In this study, we use live-cell fluorescence microscopy to investig...

摘要:Globally, rising temperatures are increasingly favoring warm-affiliated species. Although changes in community composition are typically measured by the mean temperature affinity of species (the community temperature index, CTI), they may be driven by different processes and accompanied by shifts in the diversity of temperature affinities and breadth of species thermal niches. To resolve the pathways to community warming in Finnish flora and fauna, we examined multidecadal changes in the domin...

摘要:The nature of solid phases and cross-over of order-disorder phase transitions from twodimensional (2D) layers to three-dimensional (3D) bulk in confined atomic systems remain largely unexplained. To this end, we consider noble gases and aluminum confined between graphene sheets at different pressures and temperatures. Using crystal structure search methods and molecular dynamics based on machine-learned potentials with quantum-mechanical accuracy, we identify structures of multilayer confined ...

摘要:Chronic inflammatory skin disorders are characterized by keratinocyte hyperproliferation and hyperactivation as well as immune cell infiltration. We investigated whether immune cell-derived acetylcholine (ACh) is a modulator of skin inflammation in mice. Here, we identify skin epithelial B cells as a key source of ACh that damps down inflammation. We used imiquimod (IMQ) to induce inflammatory skin disease (ISD) in mice lacking ACh production specifically in B cells (ChATfl/fl;Mb1-Cre mice). I...

摘要:Many GPCRs initiate a second phase of G protein-mediated signaling from endosomes. This inherently requires the GPCR to increase cognate G protein activity on the endosome surface. Gs-coupled GPCRs are thought to achieve this by internalizing and mediating a second round of allosteric coupling to G proteins on the endosome membrane. Here, we provide evidence that the mu- opioid receptor (MOR), a Gi-coupled GPCR, is able to increase endosomal G protein activity in a different way. Leveraging co...

摘要:UDP- glucuronic acid (UDP- GlcUA) is a nucleotide sugar essential for various biological processes in many organisms, and its excess within the cell can disrupt cellular functions. In Cryptococcus, mutations in the UXS1 gene which encodes an enzyme responsible for converting UDP- GlcUA into UDP- xylose, result in excessive accumulation of UDP- GlcUA and confer resistance to the antifungal drug 5- fluorocytosine. Here, we demonstrate that elevation of UDP- GlcUA affects several cellular process...
