Propofol Modulates Fear Memory Reconsolidation by Inhibiting D2 Receptor‐Expressing Neurons in the Medial Prefrontal Cortex

Advanced Science, EarlyView.
This study shows that propofol modulates fear‐memory reconsolidation in mice. It works by suppressing D2 receptor‐expressing neurons within the medial prefrontal cortex and their connections to the basolateral amygdala. D2‐receptor agonists reproduce this fear‐reducing effect, offering potential non‐anesthetic therapeutic strategies for trauma‐related ...

Blocking Honeybee Preference for Neonicotinoids by Interfering With Dopamine Signaling

Advanced Science, EarlyView.
Honeybees (Apis mellifera) paradoxically prefer nectar containing the harmful neonicotinoid thiamethoxam. This preference is associated with transient brain dopamine elevation during proboscis extension reflex (PER) responses and active feeding, and is reduced by the dopamine receptor antagonist fluphenazine.

Integrated Single‐Cell and Spatial Transcriptomics Reveal Convergence on a Senescence‐Associated B Cell–MIF Signaling Axis in Joint Aging and Osteoarthritis Progression

Advanced Science, EarlyView.
Single‐cell and spatial transcriptomics implicate senescent B cells and macrophage migration inhibitory factor (MIF) signaling in aging and osteoarthritic joints. An injectable hydrogel combining quercetin with siRNA targeting MIF attenuates cartilage degeneration in a mouse model of osteoarthritis.

A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

Advanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

Targeting Mitochondrial Redox Signaling Promotes Neuroregeneration and Functional Recovery in a Multiple Sclerosis Model

Advanced Science, EarlyView.
Modulation of mitochondrial redox signaling by furapyrrodole activates CYB5R3 and suppresses Notch signaling, unlocking the regenerative potential of endogenous neural progenitor cells. This approach promotes neurogenesis, oligodendrogenesis, and remyelination, thereby improving neuronal function in a mouse model of multiple sclerosis and identifying ...

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

Advanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene
