摘要:Only two nonvisual arrestins recognize many hundreds of different, intracellularly phosphorylated G protein-coupled receptors (GPCRs). Due to the highly dynamic nature of GPCR center dot arrestin complexes, the critical determinants of GPCR-arrestin recognition have remained largely unclear. We show here that arrestin2 recruitment to the R1-adrenergic receptor (R1AR) can be induced by an arrestin-activating phosphopeptide that is not covalently linked to the receptor and that the recruitment i...

摘要:Intermolecular interactions underlie all cellular functions, yet visualizing these interactions at the single-molecule level remains challenging. Single-molecule localization microscopy (SMLM) offers a potential solution. Given a nanoscale map of two putative interaction partners, it should be possible to assign molecules either to the class of coupled pairs or to the class of noncoupled bystanders. Here, we developed a probabilistic algorithm that allows accurate determination of both the abs...

摘要:Concussions can cause debilitating symptoms despite no evidence of structural changes on diagnostic imaging. The cellular events occurring in the brain parenchyma following concussion, especially repetitive concussion, are not well elucidated. We developed a concussion model to induce a confined area of injury without causing frank hemorrhage. Using intravital microscopy, we observe activation of the vasculature that supported neutrophil rolling and platelet adhesion but no overt cellular recr...

摘要:We perceive a stable, continuous world despite drastic changes of retinal images across saccades. However, while persistent objects in daily life appear stable across saccades, stimuli flashed around saccades can be grossly mislocalized. We address this puzzle with our recently proposed circuit model for perisaccadic receptive-field (RF) remapping in the lateral interparietal area (LIP) and frontal eye fields (FEF). The model uses center-excitation/surround-inhibition connections to store a re...

摘要:The process of domestication is commonly perceived as a human achievement, and domestic species are typically assumed to be those under human control. Domestic species have emerged from a greater diversity of interactions than this perspective allows, and none of the many definitions proposed for domestication can readily, reliably, and consistently distinguish domestic and nondomestic populations. Here, we propose that the process of domestication should instead be defined solely as evolution...

摘要:Distribution networks, with large-scale integration of distributed renewable resources, particularly rooftop solar photovoltaic systems, represent the most extensive yet vulnerable components of modern electric power systems during climate extremes such as hurricanes. However, existing day-ahead electricity dispatch approaches primarily focus on the transmission network and lack the capability to manage the spatiotemporal risks associated with the vast distribution networks, which can potentia...

摘要:State- of- the- art synthesis strategies of two- dimensional (2D) materials have been designed following the nucleation- dominant pattern for structure control. However, this classical methodology fails to achieve the precise layer- and stacking- resolved growth of wafer- scale few- layer 2D materials due to its intrinsically low energy resolution. Here, we present an intelligent self- correcting method for the high- resolution growth of uniform few- layer graphene. We demonstrate the layer- r...

摘要:Recent increases in woody plant density in dryland ecosystems-or woody encroachment-around the world are often attributed to land-use changes such as increased livestock grazing and wildfire suppression or to global environmental trends (e.g., increasing atmospheric carbon dioxide). While such changes have undoubtedly impacted ecosystem structure and function, the evidence linking them to woody encroachment is mixed, and the underlying processes are not fully understood. To clarify the role of...

摘要:Cystic fibrosis (CF) is a lethal genetic disorder caused by variants in CF transmembrane conductance regulator (CFTR). Many variants are treatable with correctors, which enhance the folding and trafficking of CFTR. However, approximately 3% of persons with CF harbor poorly responsive variants. Here, we used affinity purification mass spectrometry proteomics to profile the protein homeostasis (proteostasis) changes of CFTR variants during correction to assess modulated interactions with protein...
