Reading the evidence in bones, joints, muscles and skin
Joint, bone, muscle and skin conditions are often judged by pain scores, function questionnaires, imaging or photographs, and symptoms can fluctuate, so placebo response and natural improvement matter. Imaging changes are common in people without symptoms. Nothing on this page is advice about treatment. Check how outcomes were measured, whether the comparison group received a placebo or usual care, and how long the benefit lasted.
Evidence from open-access studies
These open-access studies come from PubMed’s best-match results for this heading (papers whose main topic it is), ranked here by citation count, with one recent addition. Each abstract is reproduced in full under its recorded open licence so that you can read the authors’ own words. They illustrate the literature; they are not a systematic summary of it. Citation counts measure attention, not reliability or clinical benefit.

Intervertebral disc degeneration is a leading contributor to chronic back pain and disability worldwide. This review comprehensively explores the complex interplay of cellular, molecular, and biomechanical alterations within the disc microenvironment that underlie intervertebral disc degeneration pathophysiology. Emphasis is placed on extracellular matrix degradation, cellular senescence, inflammation, oxidative stress, angiogenesis, and multiple forms of programmed cell death including apoptosis, pyroptosis, and ferroptosis. An in-depth analysis of key signaling pathways and regulatory molecules illustrates how these processes disrupt homeostasis and drive disease progression. Additionally, the review highlights emerging therapeutic approaches aimed at modifying the disc microenvironment, including mesenchymal and notochordal cell-based therapies, senolytics, ferroptosis inhibitors, gene therapy, and biomaterial innovations such as hydrogels, scaffolds, and nanocarriers. These strategies target degenerative cascades at the molecular level and represent a shift toward regenerative and disease-modifying interventions. While several approaches show promise in preclinical and early clinical studies, challenges related to safety, delivery, and long-term efficacy remain. This review underscores the importance of integrating molecular insights with translational innovations to develop targeted therapies for intervertebral disc degeneration and guide future research efforts.

Chronic lower back pain (LBP) is the leading cause of disability worldwide. Due to its close relationship with intervertebral disc (IVD) degeneration (IVDD), research has historically focused more on understanding the mechanism behind IVDD while clinical efforts prioritize pain management. More recently, there has been a shift toward understanding LBP as a distinct pathological entity. This review synthesizes current knowledge on discogenic LBP, combining known pathophysiology, molecular mechanisms, risk factors, diagnostic challenges, and available experimental models. IVDD is a complex, multifactorial process involving biochemical, mechanical, and inflammatory changes within the disc, leading to structural breakdown and potential discogenic pain. Key mechanisms include extracellular matrix degradation, upregulation of inflammatory mediators, immune cell infiltration, and aberrant nerve and vascular ingrowth. However, not all cases of IVDD result in LBP, highlighting the need for further investigation into the cellular, molecular, and biomechanical factors contributing to symptom development. Current diagnostic tools and experimental models for studying discogenic LBP remain limited, impeding the development of targeted treatments. Existing therapies primarily focus on symptom management rather than addressing underlying disease mechanisms.

Cellular mechanotransduction, essential for many biological functions, involves the conversion of mechanical signals into biochemical signals related to cell activities and metabolism. Physical factors in the local cellular microenvironment include external mechanical forces, mechanical stimulation generated by the extracellular matrix and intercellular mechanical interactions mediated through cell-cell adhesions. Intervertebral disc degeneration (IDD) is a complex pathological process involving diverse etiological contributors, such as mechanical wear, oxidative damage and nutritional deficiency. Notably, aberrant mechanical loading has been identified as a pivotal driver in both the initiation and progression of IDD. The mechanical microenvironment in intervertebral discs mainly includes pressure, tension, hydrostatic pressure, osmotic pressure and extracellular matrix stiffness. A thorough understanding of the mechanotransduction process of intervertebral disc cells in response to various mechanical stimuli and its regulatory mechanism is of great significance for the prevention and treatment of IDD. Here, therefore, we systematically review the research progress in understanding the mechanical microenvironment and mechanotransduction in IDD.

ROS-Responsive Wedelolactone Hydrogel Promotes Intervertebral Disc Repair by Disrupting the NF-κB-LCN2 Inflammatory Feedback Loop [4]

Intervertebral disc degeneration (IVDD) is driven by persistent inflammation-oxidative stress that disrupts annulus fibrosus (AF) homeostasis. Guided by network pharmacology and docking, we prioritized the NF-κB-LCN2 axis as a druggable target of wedelolactone (WDL). To achieve targeted modulation, we engineered a dual-network ROS-responsive hydrogel (WPG) in which a phenylboronic-ester/PVA redox-cleavable network interpenetrates a covalently crosslinked GelMA-elastin matrix, enabling mechanically robust yet stimulus-triggered WDL release. WDL suppressed NF-κB activation and downregulated LCN2 in both macrophages and AF cells. Conditioned-medium co-culture demonstrated that WDL disrupts macrophage-derived LCN2-mediated paracrine amplification, breaking the self-sustaining inflammatory loop. Bulk RNA-seq across both cell types revealed coordinated downregulation of NF-κB - driven chemokine cascades and restoration of adhesion and ECM gene programs following WPG treatment. In a rat AF-defect model, intradiscal WPG administration preserved disc height and T2-weighted MRI signal, reduced MMP13 while increasing Collagen I and Aggrecan expression, suppressed nuclear P-p65 and LCN2, and improved segment biomechanics-without eliciting adverse hematological or organ responses. Collectively, these findings establish that aligning molecular targeting (NF-κB-LCN2 modulation) with the pathophysiological context via ROS-gated delivery provides a synergistic strategy for AF repair and attenuation of IVDD progression.
