Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

Advanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

MRI and non-cartilaginous structures in knee osteoarthritis

, 2006
SummaryMagnetic resonance imaging (MRI) provides a sensitive tool for examining all the structures involved in the osteoarthritis (OA) process. While much of the MRI literature previously focussed on cartilage, there is increasing research on whole-organ

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Osteoarthritis and Ageing

European Medical Journal, 2018
Ageing is a complex process of accumulation of molecular, cellular, and organ damage, leading to loss of function and increased vulnerability to disease and death, the rate and extent of which varies among individuals. Osteoarthritis (OA) is not only the most common joint disease, but is also one of the major causes of disability in people aged >65 ...

Bone Marrow Aspirate Concentrate-Enhanced Marrow Stimulation of Chondral Defects

Stem Cells International, 2017
Mesenchymal stem cells (MSCs) from bone marrow play a critical role in osteochondral repair. A bone marrow clot forms within the cartilage defect either as a result of marrow stimulation or during the course of the spontaneous repair of osteochondral ...

Senolytic Therapy as a Preventive Strategy for Spine Degeneration and Pain

Advanced Science, EarlyView.
Cellular senescence promotes inflammation, tissue degeneration, and chronic back pain. In sparc‐null mice, early oral administration of the senolytic agents o‐vanillin and RG‐7112 reduced senescent cell burden and pro‐inflammatory SASP signaling across intervertebral discs, endplates, vertebral bone, and spinal cord.

Numerical analysis of cartilage surfaces for osteoarthritis diagnosis using field and feature parameters

, 2011
Osteoarthritis (OA) is one of the most common degenerative wear diseases of knee joints worldwide. Within knee joint articular cartilage (AC), collagen structure losing integrity is a major symptom of OA.

An Implantable Optogenetics‐Engineered Hydrogel for Amelioration of Rheumatoid Arthritis through Light‐Controlled Metabolic Reprogramming of Synovial Macrophages

Advanced Science, EarlyView.
An implantable hydrogel is designed to enable in situ and on‐demand secretion of GLP‐1 in synovium through blue light irradiation to activate GLP‐1R/HK2/VDAC1 pathway for upregulating tricarboxylic acid cycle and oxidative phosphorylation in macrophage, facilitating tissue repair and bone erosion recovery.
