Опубликована: Янв. 2, 2023

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.

The prevalence of heart failure is on the rise and imposes a major health threat, in part, due to rapidly increased overweight obesity. To this point, epidemiological, clinical, experimental evidence supports existence unique disease entity termed "obesity cardiomyopathy," which develops independent hypertension, coronary disease, other diseases. Our contemporary review evaluates for pathological condition, examines putative responsible mechanisms, discusses therapeutic options disorder. Clinical findings have consolidated presence left ventricular dysfunction Experimental investigations uncovered pathophysiological changes myocardial structure function genetically predisposed diet-induced Indeed, consolidates wide array cellular molecular mechanisms underlying etiology obesity cardiomyopathy including adipose tissue dysfunction, systemic inflammation, metabolic disturbances (insulin resistance, abnormal glucose transport, spillover free fatty acids, lipotoxicity, amino acid derangement), altered intracellular especially mitochondrial Ca2+ homeostasis, oxidative stress, autophagy/mitophagy defect, fibrosis, dampened flow reserve, microvascular (microangiopathy), endothelial impairment. Given important role risk failure, that with preserved systolic recent rises COVID-19-associated cardiovascular mortality, should provide compelling cardiomyopathy, various comorbid conditions, offer new insights into potential approaches (pharmacological lifestyle modification) clinical management cardiomyopathy.

Pressure overload-induced pathological cardiac hypertrophy is a common predecessor of heart failure, the latter which remains major cardiovascular disease with increasing incidence and mortality worldwide. Current therapeutics typically involve partially relieving heart's workload after onset failure. Thus, more pathogenesis-, stage-, cell type-specific treatment strategies require refined dissection entire progression at cellular molecular levels.By analyzing transcriptomes 11,492 single cells identifying types, including both cardiomyocytes noncardiomyocytes, on basis their signatures, different stages during pressure in mouse model, we characterized spatiotemporal interplay among tested potential pharmacological to retard its vivo.We illustrated dynamics all cardiomyocytes, endothelial cells, fibroblasts, macrophages, as well those respective subtypes, disease. Cellular crosstalk analysis revealed stagewise utilization specific noncardiomyocytes deterioration function. Specifically, macrophage activation subtype switching, key event middle-stage hypertrophy, was successfully targeted by Dapagliflozin, sodium glucose cotransporter 2 inhibitor, clinical trials for patients TD139 Arglabin, two anti-inflammatory agents new diseases, preserve function attenuate fibrosis. Similar patterns were also observed human patient samples hypertrophic cardiomyopathy failure.Together, our study not only dynamically changing type but shed light type- stage-specific intervention diseases.

Abstract Ischemia-reperfusion (I/R) injury paradoxically occurs during reperfusion following ischemia, exacerbating the initial tissue damage. The limited understanding of intricate mechanisms underlying I/R hinders development effective therapeutic interventions. Wnt signaling pathway exhibits extensive crosstalk with various other pathways, forming a network system pathways involved in injury. This review article elucidates signaling, as well complex interplay between and including Notch, phosphatidylinositol 3-kinase/protein kinase B, transforming growth factor-β, nuclear factor kappa, bone morphogenetic protein, N-methyl-D-aspartic acid receptor-Ca 2+ -Activin A, Hippo-Yes-associated toll-like receptor 4/toll-interleukine-1 domain-containing adapter-inducing interferon-β, hepatocyte factor/mesenchymal-epithelial transition factor. In particular, we delve into their respective contributions to key pathological processes, apoptosis, inflammatory response, oxidative stress, extracellular matrix remodeling, angiogenesis, cell hypertrophy, fibrosis, ferroptosis, neurogenesis, blood-brain barrier damage Our comprehensive analysis reveals that activation canonical promotes organ recovery, while non-canonical exacerbates Moreover, explore novel approaches based on these mechanistic findings, incorporating evidence from animal experiments, current standards, clinical trials. objective this is provide deeper insights roles its I/R-mediated processes dysfunction, facilitate innovative agents for

Mechanoregulation of YAP and TAZ in Cellular Homeostasis and Disease Progression

Frontiers in Cell and Developmental Biology, Год журнала: 2021, Номер 9

Опубликована: Май 24, 2021

Biophysical cues, such as mechanical properties, play a critical role in tissue growth and homeostasis. During organ development injury repair, compressive tensional forces generated by cell-extracellular matrix or cell-cell interaction are key factors for cell fate determination. In the vascular system, hemodynamic forces, shear stress, cyclic stretch modulate phenotypes susceptibility to atherosclerosis. Despite that emerging efforts have been made investigate how mechanotransduction is involved tuning functions various contexts, regulatory mechanisms remain largely unknown. One of challenges understand signaling cascades transmit cues from plasma membrane cytoplasm then nuclei generate mechanoresponsive transcriptomes. YAP its homolog TAZ, Hippo pathway effectors, identified mechanotransducers sense stimuli relay signals control transcriptional programs proliferation, differentiation, transformation. However, upstream mechanosensors YAP/TAZ downstream transcriptome responses following activation repression not well characterized. Moreover, mechanoregulation literature highly context-dependent. this review, we summarize biomechanical microenvironment provide an update on roles physiological pathological conditions.
