Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

open access: yesAdvanced Science, EarlyView.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

Type I Interferon Signaling Augments Autoimmunity in Neuromyelitis Optica Spectrum Disorder

open access: yesAdvanced Science, EarlyView.
The cGAS‐STING innate immune pathway is excessively activated both in peripheral monocytes and CNS microglia in patients with NMOSD, leading to an overproduction of IFN‐I. IFN‐I subsequently acts on AQP4‐specific autoreactive T cells. Blocking this pathway may offer novel therapeutic options for individuals with NMOSD.

Sleep Deprivation Aggravates Periodontitis Through Trigeminal‐Periodontal Neuroimmune Pathway Mediated by the AChE‐ACh‐α7nAChR Axis

open access: yesAdvanced Science, EarlyView.
Sleep deprivation (SD) exacerbates ligature‐induced periodontitis (LIP) through the trigeminal nerve‐periodontal neuroimmune pathway mediated by the acetylcholinesterase (AChE)‐acetylcholine (ACh)‐α7 nicotinic receptor (α7nAChR) axis. While electroacupuncture (EA) alleviates the condition of LIP combined with SD by activating the α7nAChR.

Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

open access: yesAdvanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

Extracellular LCN2 Binding to 24p3R in Astrocytes Impedes α‐Synuclein Endocytosis in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
24p3R is an astrocytic receptor for α‐Syn uptake. When LCN2 is secreted from astrocytes, it binds to its receptor 24p3R in astrocytes and this binding impedes the α‐Syn PFF binding to 24p3R. This in turn inhibits 24p3R‐mediated α‐Syn PFF uptake and reduces the clearance of extracellular α‐Syn by astrocytes, which contributes to α‐Syn spread and ...

Post‐Translational Modified Neoantigens in Autoimmune Diseases: Challenges of Immune Tolerance

open access: yesAdvanced Science, EarlyView.
Autoimmune diseases have a high incidence and disability rate. The pathogenesis of autoimmune diseases involves the interaction among genetic factors, environmental factors, and immune disorders. The post‐translational modified neoantigens are the key nodal of these three factors. And these post‐translational modified neoantigens, after being presented

A Peripheral Mechanism of Depression: Disturbed Intestinal Epithelial Per2 Gene Expression Causes Depressive Behaviors in Mice with Circadian Rhythm Disruption via Gut Barrier Damage and Microbiota Dysbiosis

open access: yesAdvanced Science, EarlyView.
Circardian rhythm disorder (CRD) causes abnormal expression of intestinal Period 2 (Per2) gene, which compromising intestinal barrier integrity and altering the gut microenvironment. Microbiota dysbiosis and aberrant metabolites production drive central inflammation, impair neurogenesis, and promote functional deficits, ultimately facilitating the ...

Activation of Kir4.1 Channels by 2‐D08 Promotes Myelin Repair in Multiple Sclerosis

open access: yesAdvanced Science, EarlyView.
Multiple sclerosis causes myelin loss and neurological dysfunction. This study shows that 2‐D08, a small molecule targeting Kir4.1 channels, promotes OPCs differentiation via FYN tyrosine kinase phosphorylation and the FYN/MYRF pathway. It significantly improves myelin repair and motor deficits in EAE mice and marmosets, highlighting its potential as a

PIEZO1‐GPX4 Axis Mediates Mechanical Stress‐Induced Vertebral Growth Plate Dysplasia via Ferroptosis Activation

open access: yesAdvanced Science, EarlyView.
Mechanical stress activates PIEZO1 in vertebral growth plate chondrocytes, triggering ferroptosis through direct binding and inhibition of GPX4. This axis promotes lipid peroxidation and pathological ossification, accelerating spinal deformities. Clinical and genetic evidence (Piezo1‐cKO) confirms its role in scoliosis progression.

Long Term High‐Salt Diet Induces Cognitive Impairments via Down‐Regulating SHANK1

open access: yesAdvanced Science, EarlyView.
The study identifies a novel mechanistic link between long‐term HS diet and cognitive impairment, wherein PKA/CREB axis inactivation leads to SHANK1 reduction, synaptic damage, and cognitive deficits. Abstract High‐salt (HS) diet is an established risk factor for cognitive impairment, but the underlying mechanisms remain unclear.
