Platelet COX and LOX enzymes orchestrate amyloid-β secretion via RhoA signaling: Implications for neurodegenerative diseases

Arachidonic acid metabolism through cyclooxygenase (COX) and lipoxygenase (LOX) pathways is fundamental to inflammation, vascular homeostasis, and neuronal signaling. Here, we investigated the roles of platelet-expressed COX (PTGS1) and LOX (ALOX12) isoforms in amyloid-β (Aβ) secretion, a process im...
