Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

Advanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...

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

Advanced 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 ...

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

Advanced 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

Wearable Bioelectronics for Home‐Based Monitoring and Treatment of Muscle Atrophy

Advanced Science, EarlyView.
As an inevitable disease, muscle atrophy has received more attention. Because the factors that induce this disease are diverse, achieving a complete cure is still impossible. Wearable bioelectronics provides a more comfortable, low‐cost, and efficient way of home care for the monitoring and treatment of muscle atrophy. Therefore, this review summarizes

A Myelin Debris Cleaner for Spinal Cord Injury Recovery: Polycaprolactone / Cell Membrane Assembled Scaffolds

Advanced Science, EarlyView.
pMM‐PCL, made up of pretreated macrophage menbrane and polycaprolactone, boasts the adsorption of harmful myelin debris in the microenvironment of spinal cord injury. Abstract After spinal cord injury (SCI), a mass of myelin debris derived from injured myelin sheath will be consistently generated and induce macrophages to be foam cells.

3D‐Printing of Electroconductive MXene‐Based Micro‐Meshes in a Biomimetic Hyaluronic Acid‐Based Scaffold Directs and Enhances Electrical Stimulation for Neural Repair Applications

Advanced Science, EarlyView.
This study combined microscale 3D‐printing with 2D Ti3C2Tx MXene nanosheets to produce electroconductive microfibrous micro‐meshes. By embedding these MXene‐functionalized micro‐meshes within a growth‐supportive macroporous extracellular matrix (ECM)‐based biomaterial, multifunctional biomimetic MXene‐ECM scaffolds were developed.
