Genomic and Cis‐Regulatory Basis of a Plastic C3‐C4 Photosynthesis in Eleocharis Baldwinii

Advanced Science, EarlyView.
The sedge Eleocharis baldwinii remarkably switches between C3‐like and C4‐like photosynthesis in response to environmental conditions. Combining gap‐free genome assembly with single‐cell multi‐omics, this study uncovers how subgenome dominance and cell‐specific cis‐regulation enable C4 photosynthesis.

Engineered Foxp1high Exosomes Ameliorates Systemic Lupus Erythematosus

Advanced Science, EarlyView.
This study presents a dual‐engineering strategy combining mesenchymal stem cell aggregation and Foxp1 overexpression to generate Foxp1high aggregation exosomes with enhanced immunomodulatory properties. These engineered exosomes exhibit immune organ targeting and superior efficacy in systemic lupus erythematosus treatment by promoting Treg ...

Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

Post‐Translational Modifications in Cilia and Ciliopathies

Advanced Science, EarlyView.
This review synthesizes current understanding of post‐translational modifications (PTMs) in ciliary proteins and emphasizes their roles in ciliary formation, homeostasis, and signaling. This review also discusses the implication of PTM dysregulation in ciliopathies and explores therapeutic strategies targeting PTM‐modifying enzymes.
