β-arrestin1 promotes tauopathy by transducing GPCR signaling, disrupting microtubules and autophagyGPCRs regulator, β-arrestin1, is increased in FTLD-tau patients, is required for β2-adrenergic receptor and metabotropic glutamate receptor 2-induced tau phosphorylation, promotes tau aggregation by impairing autophagy, and destabilizes microtubule dynamics, whereas genetic reduction in β-arrestin1 mitigates tauopathy and cognitive impairments.
Bis-choline tetrathiomolybdate prevents copper-induced blood–brain barrier damageThe blood–brain barrier endothelial cell monolayer becomes permeable to elevated copper loosely bound to albumin, which can be avoided by a high-affinity copper chelator but not by D-penicillamine.
Transcriptomics reveals immune-metabolism disorder in acute-on-chronic liver failure in ratsLiver tissue transcriptomics of liver cirrhosis (LC)–based acute-on-chronic liver failure (ACLF) rats reveal immune-metabolism disorder as the core mechanism underlying ACLF development and prognosis.
Fundamentals of vaping-associated pulmonary injury leading to severe respiratory distressVaping promotes pathological structural remodeling and functional impairment of the cardiopulmonary system in a mouse inhalation model. This model of vaping-associated pulmonary injury (VAPI) demonstrates potential health risks and provides mechanistic insights on cellular and molecular levels.
Bimodal fibrosis in a novel mouse model of bleomycin-induced usual interstitial pneumoniaA novel mouse model of induced-usual interstitial pneumonia shows bimodal fibrosis with honeycombing, similar to chronic lung disease seen with idiopathic pulmonary fibrosis.
Single-domain antibody screening by isPLA-seqThis study describes a high-sensitive, high-throughput single-domain antibody library screening approach, which is applicable for any given interested protein at single-cell resolution by isPLA-seq.
Autoimmune anti-DNA and anti-phosphatidylserine antibodies predict development of severe COVID-19COVID-19 induces high levels of autoimmune anti-DNA and anti-phosphatidylserine antibodies that are detected in some patients upon hospital admission and predict later development of severe disease.
Serum proteomics reveals disorder of lipoprotein metabolism in sepsisThis study illustrated that lipoprotein and lipid metabolism might play a significant role in patients with sepsis and that complement activation was significantly enriched in patients with sepsis-associated encephalopathy.
Improved systemic AAV gene therapy with a neurotrophic capsid in Niemann–Pick disease type C1 miceThis work highlights the importance of CNS transduction for treatment of neurological diseases, a finding with significant clinical implications considering the long-lasting effects of gene therapy.
Negative correlation of single-cell PAX3:FOXO1 expression with tumorigenicity in rhabdomyosarcomaSingle-cell PAX3:FOXO1 expression in rhabdomyosarcoma is variable. PAX3:FOXO1 low cell states are characterized by more efficient adhesion, migration and tumor-propagating capacity.
