PS2 wild-type (WT) and mutant (MT) mice aged 12-15 months were subjected to unpredictable chronic mild stress (UCMS) for 4 weeks, followed by sucrose preference, tail-hanging, and forced swimming tests.

Gene expression profiling of human hippocampal datasets confirmed upregulation of NOTCH2 in Alzheimer's disease and depression. Pharmacological inhibition of γ-secretase and Notch signaling with DAPT normalizes depressive behavior, reduces corticosterone release, attenuates GR phosphorylation, and inhibits Notch2 signaling in PS2 MT mice.

In vitro, oleic acid-induced hepatocytes were treated with licochalcone E to investigate its effect on lipid metabolic pathways. In animal experiments, male C57BL/6 mice were fed with a high-fat diet (HFD) and treated with licochalcone E by intraperitoneal injection for 12 weeks to assess its effects on biochemical indexes and hepatic steatosis. Furthermore, mice were fed a methionine/choline-deficient (MCD) diet and administered licochalcone E, followed by evaluation of liver fibrosis.

Licochalcone E treatment of obese mice also reduced hepatic lipid accumulation and improved hepatocyte steatosis. Licochalcone E regulated the expression of lipogenesis- and lipolysis-related genes in the livers of obese mice and increased AMPK phosphorylation and Sirt1 expression in the liver. Licochalcone E also attenuated hepatic inflammation and oxidative stress in obese mice. Furthermore, treatment of MCD-induced mice with licochalcone E reduced the number of lipid vacuoles and the extent of fibrosis and inhibited liver inflammation.

Ferroptotic chondrocytes release reactive lipid species and damage-associated molecular patterns (DAMPs) that induce paracrine senescence in neighboring cells, while senescent cells amplify oxidative stress and ferroptotic susceptibility, forming a self-perpetuating feed-forward loop that accelerates tissue degeneration. Histological, molecular, and in vivo studies demonstrate iron accumulation, lipid peroxidation, glutathione peroxidase 4 (GPX4) depletion, and SASP factor secretion in human OA cartilage, synovium, and animal models, linking these processes to ECM breakdown and joint inflammation.

Integration of biomarker-guided patient stratification, advanced imaging, and spatial transcriptomic profiling may enable precision-targeted, disease-modifying therapies.

The HBM-derived exosomes treatment decreased the expression of inflammatory mediators and proinflammatory cytokines in mouse peritoneal macrophages upon lipopolysaccharide stimulation.

Extracellular adenosine accumulates during wakefulness as a result of neuronal energy metabolism, particularly in the basal forebrain, and declines during recovery sleep, thereby reflecting the physiological need for sleep. The sleep-promoting effects of adenosine are mediated primarily by two G protein-coupled receptor subtypes, the adenosine A<sub>1</sub> receptor and the adenosine A<sub>2A</sub> receptor. The adenosine A<sub>1</sub> receptor, coupled to inhibitory Gi/o proteins and widely expressed in the cortex, hippocampus, thalamus, and basal forebrain, suppresses wake-promoting neuronal activity and facilitates slow-wave activity during non-rapid eye movement sleep. In contrast, the adenosine A<sub>2A</sub> receptor, coupled to stimulatory Golf proteins and enriched in the striatum and nucleus accumbens, promotes sleep by activating neurons in the preoptic hypothalamus and engaging the indirect basal ganglia pathway. Despite these well-established roles, the contributions of dysregulation of the adenosine A<sub>1</sub> receptor and the adenosine A<sub>2A</sub> receptor to specific sleep disorders remain incompletely understood.
