Epoxy-Oxylipins as a Potential Means to Reduce Chronic Inflammation
Researchers have identified soluble epoxide hydrolase (sEH) inhibition as a means to boost epoxy‑oxylipin levels, notably 12,13‑EpOME and 14,15‑EET, in humans. Elevated epoxy‑oxylipins selectively reduce intermediate monocytes through p38 MAPK inhibition, accelerating pain resolution while leaving acute inflammatory markers largely unchanged. The approach uncouples chronic inflammatory cell activity from essential short‑term immune responses, offering a targeted strategy to mitigate age‑related inflammatory diseases. Clinical data already confirm the safety profile of sEH inhibitors, positioning them for rapid therapeutic development.

Reduced Mechanical Stimulation in Aged Bone Marrow Contributes to Cell Dysfunction
Researchers discovered that aging diminishes mechanical stimulation in bone marrow, lowering intracellular traction forces of mesenchymal stem cells. Applying low‑frequency vibration restores these forces, re‑opening chromatin and reactivating FOXO1 transcription. The mechanical rescue improves locomotor activity, reduces frailty, and dampens...
