WTAP‐Mediated m6A Modification Targets the LRP1‐Lipid Metabolism Axis to Regulate Joint Cartilage Regeneration

Advanced Science, EarlyView.
WTAP drives cartilage regeneration by activating an LRP1‐dependent lipid metabolic program in macrophages, enhancing IL‐10 and TGF‐β secretion to promote chondrogenic differentiation. Leveraging this mechanism, virtual screening identifies LRP1‐targeting compounds that effectively stimulate cartilage repair, highlighting a druggable epigenetic ...

Possibility of using the infrapatellar (Hoffa’s) fat pad as a source of autologous stem cells

Сибирский научный медицинский журнал, 2020
Stem cells are the basis for the creation of tissue-engineered structures in regenerative medicine. The most well-studied sources of stem cells are the embryo and bone marrow.

Anti‐inflammatory and osteogenic effects of transcutaneous electrical nerve stimulation in knee osteoarthritis rats via the regulation of the intestinal microbiota

Animal Models and Experimental Medicine, EarlyView.
Transcutaneous electrical nerve stimulation (TENS) improved knee osteoarthritis (KOA) in rats by regulating interleukin‐1β (IL‐1β), IL‐6, and IL‐8 expressions and the bone morphogenetic protein 2 (BMP‐2)/transforming growth factor β (TGF‐β) signaling pathway.

The Potential Role of Synovial T Cell Infiltration Following Knee Joint Injury in Symptoms and Progression to Osteoarthritis

Arthritis &Rheumatology, EarlyView.
Objective Identification of osteoarthritis (OA)–specific synovial inflammatory pathways and their temporal relevance is critical for therapeutic targeting. We compared mononuclear inflammatory/immune cell responses following joint injury that does or does not lead to OA to define bona fide OA‐associated cellular events.

CD8+ T‐cells, CD86+ macrophages and TNF‐α signalling pathways are correlated with fetlock osteoarthritis in racehorses

Equine Veterinary Journal, EarlyView.
Abstract Background There is emerging evidence for the role of the immune system in osteoarthritis (OA) pathophysiology; however, little is known about how immune cells and the synovial transcriptome are altered in naturally occurring equine OA. Objectives To evaluate synovial fluid (SF) and synovial membrane (SM) immune cell populations and the SM ...

Epigenomic profiling of the infrapatellar fat pad in osteoarthritis. [PDF]

Hum Mol Genet, 2023
Abstract Osteoarthritis is a prevalent, complex disease of the joints, and affects multiple intra-articular tissues. Here, we have examined genome-wide DNA methylation profiles of primary infrapatellar fat pad and matched blood samples from 70 osteoarthritis patients undergoing total knee replacement surgery.

Mapping Fatty Acid Composition in the Human Knee: Short‐Term Repeatability at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Alterations in periarticular lipid composition are implicated in musculoskeletal diseases, yet short‐term reliability of MRI‐based triglyceride composition mapping in the knee is not fully established. Purpose To evaluate 1‐week repeatability of proton‐density fat fraction (PDFF) and triglyceride fatty‐acid composition—saturated ...

Phenotypic and functional properties of dedifferentiated fat cells derived from infrapatellar fat pad

Regenerative Therapy, 2022
Introduction: Mature adipocyte-derived dedifferentiated fat cells (DFATs) are mesenchymal stem cell (MSC)-like cells with high proliferative ability and multilineage differentiation potential.

Osteoarthritis: An Immuno‐Inflammatory Disease‐Mechanisms of Immune Cell Dysregulation and Potential Therapeutic Strategies

Med Research, EarlyView.
This review summarizes the immuno‐inflammatory mechanisms driving the pathogenesis of osteoarthritis (OA), extending beyond the traditional view of OA as a purely degenerative disease to incorporate immune cell infiltration, inflammatory factor release, and the formation of a chronic low‐grade inflammatory microenvironment.

Exploratory pilot study of infrapatellar fat pad inflammation and treatment response in anterior knee pain: a single-center, ultrasound-guided injection trial in osteoarthritis and non-OA cohorts

Egyptian Rheumatology and Rehabilitation
Background Osteoarthritis (OA) is a leading cause of knee pain, and the infrapatellar fat pad (IPFP) may play a role via local inflammation. Objective This exploratory pilot study assessed infrapatellar fat pad (IPFP) inflammation using Doppler ...
