Decanoic acid additively suppresses IL-1β and enables pharmacologic dexamethasone dose-sparing in LPS/ATP-stimulated THP-1 macrophages

Systemic inflammatory response syndrome, driven by trauma or infection, involves excessive innate immune activation. Dexamethasone (DEX), a synthetic glucocorticoid, suppresses inflammation, although adverse side effects limit its clinical use. The inflammasome, a multiprotein complex that assembles in response to infl...

Decanoic acid reduces extracellular prostaglandin accumulation, inhibits MRP4 transport, and enhances low-dose dexamethasone effects in IL-1β-stimulated human osteoarthritis synoviocytes

Objective Persistent extracellular prostaglandin signaling contributes to synovial inflammation and pain in osteoarthritis (OA), although prostaglandin E2 (PGE2) can also have context-dependent homeostatic functions. Decanoic acid (DA) is a 10-carbon medium-chain fatty acid with reported peroxisome proliferator-activat...

Complementary Regulation of Inflammatory, Catabolic, and PPARγ Signaling by Dexamethasone and Decanoic Acid in Donor-Specific Human Chondrocyte Models

Background/Objectives: This study examined whether dexamethasone (Dex) and decanoic acid (DA) exert complementary effects on inflammatory signaling, catabolic gene expression, and peroxisome proliferator-activated receptor gamma (PPARγ) activation in human chondrocytes. Methods: Two donor-specific primary human chondro...

Aging as Loss of Biological Self-Correction: A Geroscience Framework for Longevity, Inflammaging, and Restored Resilience

A complementary conceptual framework in which aging is viewed as progressive impairment of biological self-correction: the distributed capacity to sense consequential perturbations, scale an appropriate response, scale an appropriate response, repair or remove damage, terminate the response, and recover or adaptively r...
