Background/aims: Thyroid hormones have been recently linked to senescence and longevity. Given the recent description of TSHB mRNA in human adipose tissue (AT), we aimed to investigate the relationship between local AT TSH and adipose tissue senescence.
Methods: TSHB mRNA (measured by real-time PCR) and markers of adipose tissue senescence [BAX, DBC1, TP53, TNF (real-time PCR), telomere length (Telo TAGGG Telomere Length Assay) and lipidomics (liquid chromatography mass spectrometry)] were analysed in subcutaneous (SAT) and visceral (VAT) AT from euthyroid subjects. The chronic effects of TSH were also investigated in AT from hypothyroid rats and after recombinant human TSH (rhTSH) administration in human adipocytes.
Results: Both VAT and SAT TSHB gene expression negatively correlated with markers of AT cellular senescence (BAX, DBC1, TP53, TNF gene expression and specific glucosylceramides) and positively associated with telomere length. Supporting these observations, both rhTSH administration in human adipocytes and increased TSH in hypothyroid rats resulted in decreased markers of cellular senescence (Bax and Tp53 mRNA) in both gonadal and subcutaneous white adipose tissue.
Conclusion: These data point to a possible role of TSH in AT cellular senescence.

Bone healing requires Schwann cells (SCs) paracrine factors for mesenchymal stem cell function. Diabetes mellitus (DM) patients are susceptible to developing SCs dysfunction and impairing bone healing. Rare research considered reconstructing mesenchymal stem cell-schwann cell circuitry in diabetic bone regeneration.

Background: Individuals born after intrauterine growth restriction (IUGR) have a higher risk of developing metabolic syndrome (MetS) in adulthood. In a rat model, male IUGR offspring exhibit MetS features-including elevated systolic blood pressure, glucose intolerance, non-alcoholic fatty liver disease, and increased visceral adipose tissue (VAT)-by 6 months of age. Female offspring, however, do not.

The incidence of traumatic brain injury (TBI) has demonstrated a marked escalation recently. Nevertheless, there remains a critical paucity of effective drug interventions targeting persistent neuroinflammation-induced damage following TBI. STING/NF-κB axis-induced pyroptosis emerges as a pivotal mechanism driving persistent neuroinflammation, providing it as a potential target for multi-pathway precision therapeutic in TBI.

Spinal cord injury (SCI) is a devastating condition characterized by the accumulation of myelin debris (MD), persistent neuroinflammation, and impaired neural regeneration. Although macrophages are pivotal for MD clearance, the impact of excessive MD phagocytosis on macrophage phenotype and function remains poorly understood. Building upon our prior evidence that exendin-4 (Ex-4), a glucagon-like peptide-1 receptor (GLP-1R) agonist, mitigates microglia-driven neuroinflammation post-SCI, this study elucidates the therapeutic efficacy and underlying mechanisms of Ex-4 in alleviating macrophage senescence, restoring efferocytotic capacity, and facilitating neural repair.

Chronic kidney disease (CKD) substantially increases cardiovascular risk, with endothelial dysfunction as its central pathological mechanism. This review summarises the molecular regulatory mechanisms underlying endothelial dysfunction in CKD and highlights recent advances in treatment strategies. The pathophysiology of endothelial injuries involves a complex network of multiple factors and mechanisms, including oxidative stress, inflammation, glycocalyx damage, ischaemia, hypoxia, cellular senescence and endothelial-mesenchymal transition (EndMT).
