Transmembrane signaling receptors, such as integrins, organize nanoclusters that provide several advantages, including increasing avidity, sensitivity (increasing the signal-to-noise ratio), and robustness (signaling threshold) of signal in contrast to by single receptors. Furthermore, compared large micron-sized clusters, offer advantage rapid turnover for disassembly signal. However, whether function hubs remains poorly understood. Here, we employ fluorescence nanoscopy combined with photoactivation photobleaching at subdiffraction limited resolution ∼100 nm length scale within a focal adhesion examine dynamics diverse proteins.

Abstract Integrins are considered the main cell-adhesion transmembrane receptors that play multifaceted roles as extracellular matrix (ECM)-cytoskeletal linkers and transducers in biochemical mechanical signals between cells their environment a wide range of states health diseases. Integrin functions dependable on delicate balance active inactive status via multiple mechanisms, including protein-protein interactions, conformational changes, trafficking. Due to exposure cell surface sensitivity molecular blockade, integrins have been investigated pharmacological targets for nearly 40 years, but given complexity sometimes opposite characteristics, targeting integrin therapeutics has challenge. To date, only seven drugs successfully marketed, abciximab, eptifibatide, tirofiban, natalizumab, vedolizumab, lifitegrast, carotegrast. Currently, there approximately 90 kinds integrin-based therapeutic or imaging agents clinical studies, small molecules, antibodies, synthetic mimic peptides, antibody–drug conjugates (ADCs), chimeric antigen receptor (CAR) T-cell therapy, agents, etc. A serious lesson from past drug discovery research efforts is successes rely both deep understanding integrin-regulatory mechanisms unmet needs. Herein, we provide systematic complete review all family members integrin-mediated downstream signal transduction highlight ongoing develop new therapies/diagnoses bench clinic. In addition, further discuss trend development, how improve success rate trials therapies, key points research, basic translational research.

Abstract Blood protein extravasation through a disrupted blood–brain barrier and innate immune activation are hallmarks of neurological diseases emerging therapeutic targets. However, how blood proteins polarize cells remains largely unknown. Here, we established an unbiased blood-innate immunity multiomic genetic loss-of-function pipeline to define the transcriptome global phosphoproteome blood-induced polarization its role in microglia neurotoxicity. induced widespread microglial transcriptional changes, including changes involving oxidative stress neurodegenerative genes. Comparative functional multiomics showed that induce distinct receptor-mediated programs macrophages, such as redox, type I interferon lymphocyte recruitment.

Integrins link the extracellular environment to actin cytoskeleton in cell migration and adhesiveness. Rapid coordination between events outside inside is essential. Single-molecule fluorescence dynamics show that ligand binding bent-closed integrin conformation, which predominates on surfaces, followed within milliseconds by two concerted changes, leg extension headpiece opening, give high-affinity conformation. The extended-closed conformation not an intermediate but can be directly accessed from extended-open provides a pathway for dissociation. In contrast ligand, talin, links β-subunit cytoplasmic domain cytoskeleton, modestly stabilizes does induce or opening. Integrin activation thus initiated outside-in signaling inside-out signaling. Our results further imply talin insufficient tensile force transmission through ligand-integrin-talin-actin complex required.

Inspired by the extracellular matrix (ECM), biomaterials have emerged as promising strategies in biomedical research and engineering domain, offering unique characteristics for tissue regeneration, drug delivery, therapeutic interventions, cellular investigations. The ECM, a dynamic network structure secreted various cells, primarily comprises diverse proteins capable of facilitating tissue-ECM signaling regulatory functions through its rich array bioactive substances multi-level structural properties. Drawing inspiration from intricate biochemical composition natural researchers developed to encapsulate these features create biomimetic microenvironments, such electrospinning, hydrogels/hydrogel microspheres, decellularized ECM(dECM), ECM-mimicking peptides. Furthermore, mimicking ECM components, ECM-inspired exhibit varying degrees functionalization, including providing support, cell adhesion, signal transduction, mitigating immune responses, remodeling.

Many cancer cells exhibit increased amounts of paucimannose glycans, which are truncated N-glycan structures rarely found in mammals. Paucimannosidic proteins proposedly generated within lysosomes and exposed on the cell surface through a yet uncertain mechanism. In this study, we revealed that paucimannosidic produced by lysosomal glycosidases secreted via exocytosis. Interestingly, exocytosis preferentially occurred vicinity focal adhesions, protein complexes connecting actin cytoskeleton to extracellular matrix. Through genome-wide knockout screening, identified MYO18B, an crosslinker, is required for adhesion maturation, facilitating release milieu. Moreover, mechanosensitive cation channel PIEZO1 locally activated at adhesions imports Ca2+ necessary lysosome-plasma membrane fusion. Collectively, our study unveiled intimate relationship between adhesion, shedding light unexpected interplay activities cellular mechanosensing.

Redox signaling acts as a critical mediator in the dynamic interactions between organisms and their external environment, profoundly influencing both onset progression of various diseases. Under physiological conditions, oxidative free radicals generated by mitochondrial respiratory chain, endoplasmic reticulum, NADPH oxidases can be effectively neutralized NRF2-mediated antioxidant responses. These responses elevate synthesis superoxide dismutase (SOD), catalase, well key molecules like nicotinamide adenine dinucleotide phosphate (NADPH) glutathione (GSH), thereby maintaining cellular redox homeostasis. Disruption this finely tuned equilibrium is closely linked to pathogenesis wide range Recent advances have broadened our understanding molecular mechanisms underpinning dysregulation, highlighting pivotal roles genomic instability, epigenetic modifications, protein degradation, metabolic reprogramming. findings provide foundation for exploring regulation mechanistic basis improving therapeutic strategies. While antioxidant-based therapies shown early promise conditions where stress plays primary pathological role, efficacy diseases characterized complex, multifactorial etiologies remains controversial. A deeper, context-specific signaling, particularly redox-sensitive proteins, designing targeted aimed at re-establishing balance. Emerging small molecule inhibitors that target specific cysteine residues proteins demonstrated promising preclinical outcomes, setting stage forthcoming clinical trials. In review, we summarize current intricate relationship disease also discuss how these insights leveraged optimize strategies practice.
