Proteolytic remodelling of the extracellular matrix by pericytes

The FEBS Journal, Volume 293, Issue 13, Page 3899-3953, July 2026.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.

Trained Memory of Uterine Macrophages Improves Subsequent Pregnancy Outcomes

Advanced Science, Volume 13, Issue 31, 4 June 2026.
This study identifies that pregnancy imprints a durable, pregnancy‐specific form of trained immune memory in uterine macrophages, marked by the emergence of LILRB3+/PIR‐B+ cells that expand across gestations, acquire a tolerogenic and metabolically rewired phenotype, and actively protect against inflammatory pregnancy loss in mice.

Contributions of the Alzheimer's Disease Neuroimaging Initiative to advancing AD research: a targeted review of recent publications

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently celebrated its 20th anniversary, reflecting two decades of major contributions to Alzheimer's research through open data sharing and longitudinal multimodal assessments. This review synthesizes 122 high‐impact studies using ADNI data or biospecimens from 2023 to mid‐2025 to ...

Transcriptome profiling revealed early vascular smooth muscle cell gene activation following focal ischemic stroke in female rats – comparisons with males

BMC Genomics, 2020
Background Women account for 60% of all stroke deaths and are more often permanently disabled than men, despite their higher observed stroke incidence. Considering the clinical population affected by stroke, an obvious drawback is that many pre-clinical ...

A Network‐Based Approach to Understanding Key Signaling Pathways in Intervertebral Disc Biology

JOR SPINE, Volume 9, Issue 2, June 2026.
A literature‐based signaling network capturing the most relevant pathways in human nucleus pulposus cells was first constructed from curated biological evidence. The network was then translated into a system of ordinary differential equations to derive steady‐state solutions and define median baseline activity levels.

Detrimental Effect of Low‐Magnitude High‐Frequency Vibration in an Ex Vivo Model of Intervertebral Disc Degeneration Despite Estrogen Treatment

JOR SPINE, Volume 9, Issue 2, June 2026.
Low‐magnitude high‐frequency vibration (LMHFV), with or without 17β‐oestradiol (E2), exacerbated papain‐induced bovine intervertebral disc degeneration, reducing cell viability, impairing matrix production, and increasing inflammation. E2 showed no protective effect against papain‐induced degeneration or LMHFV.

Dynamics of N6‐methyladenosine modification during aging and their potential roles in the degeneration of intervertebral disc

JOR Spine
Background The N6‐methyladenosine (m6A) dynamics in the progression of intervertebral disc (IVD) aging remain largely unknown. This study aimed to explore the distribution and pattern of m6A modification in nucleus pulpous (NP) tissues of rats at ...

Nicotinamide Phosphoribosyltransferase Inhibitor APO866 Prevents IL-1β-Induced Human Nucleus Pulposus Cell Degeneration via Autophagy

Cellular Physiology and Biochemistry, 2018
Background/Aims: Intervertebral discs consist of an extracellular matrix (ECM) with a central gelatinous nucleus pulposus (NP) enclosed in an outer layer known as the annulus fibrosus.

Comparative Analysis of Dual‐miRNA Mediated Stimulation of Nucleus Pulposus and Bone Marrow Derived Stem Cells for Intervertebral Disc Repair

JOR SPINE, Volume 9, Issue 2, June 2026.
Nucleus pulposus (NP) and bone marrow derived stem cells (BMSCs) transfected with miRNA‐149‐5p‐mimic and 221‐3p‐inhibitor were evaluated in goat monolayer, microtissue, and ex vivo organ cultures of mild degeneration. miRNA‐treated NP cells demonstrated an anti‐catabolic and pro‐discogenic response in organs, highlighting its potential as a ...

Tenascin-C induces inflammatory mediators and matrix degradation in osteoarthritic cartilage

BMC Musculoskeletal Disorders, 2011
Background Tenascin-C (TN-C) is an extracellular matrix glycoprotein that is involved in tissue injury and repair processes. We analyzed TN-C expression in normal and osteoarthritic (OA) human cartilage, and evaluated its capacity to induce inflammatory ...
