Sympathetic Activation Promotes Kidney Fibrosis in Mice via Macrophage‐Derived N2ICD‐Enriched Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
Norepinephrine/α2B‐adrenoceptor axis promotes the secretion of Notch2 intracellular domain (N2ICD)‐enriched extracellular vesicles (EVs) from macrophages. These EVs deliver N2ICD into fibroblasts, thereby inducing their activation. Deletion of Notch2 or α2B‐AR in macrophages disrupts N2ICD‐enriched EV formation and alleviates kidney fibrosis in mice ...

Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron‐Mediated Lung‐to‐Brain Axis

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSC) are considered a promising alternative for neuropathic pain (NP) treatment, but underlying mechanisms remain elusive. Huang et al. illustrate that a Npy2r sensory neuron‐related lung–brain axis contributes to MSC analgesia.

SIRT6 Lysine‐Demyristoylates ATF2 to Ameliorate Vascular Injury via PRKCD/VE‐Cadherin Pathway Regulating Vascular Endothelial Barrier

open access: yesAdvanced Science, EarlyView.
A novel modified SIRT6 variant (dSIRT6) H133Y‐mediated enrichment technique unmasks 15 new human lysine‐myristoylated proteins. Notably, Sirtuin 6 (SIRT6) demyristoylation of activating transcription factor 2 (ATF2) at K296 orchestrates its nucleoplasmic translocation.

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

open access: yesAdvanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

Forelimb Motor Learning and Memory Consolidation Drives Distinct Oligodendrocyte Plasticity to Regulate Task‐related Neuronal Activity

open access: yesAdvanced Science, EarlyView.
Genetic and chemical tracking of oligodendrogenesis, combining fiber photometric neuronal activity recording, reveals that distinct oligodendrocyte plasticities are adopted during different phases of motor learning to fine‐tune task‐related neuronal activity, with a preferential involvement of oligodendrogenesis suppression and node lengthening (type 2

Microglial Deletion of Hrh4 Alleviates Alzheimer's Disease Pathologies by Enhancing Microglial Phagocytosis of Amyloid‐β and Tau

open access: yesAdvanced Science, EarlyView.
Histamine H4 receptor (H4R) antagonist VUF6002 mimics low‐dose X‐ray irradiation in aged Alzheimer's disease (AD) mice, enhancing microglial clearance of amyloid‐beta/hyperphosphorylated tau aggregates and restoring cognition. Microglial H4R deletion activates cAMP/TGF‐β1/Smad3 pathway, enhancing phagocytosis, while TGF‐β receptor 1 deletion abolishes ...
