Dose‐Dependent Biphasic Effect of Palmitic Acid on Oligodendrocyte Function: Impacts on Viability, Differentiation, and Myelination

open access: yesJournal of Cellular Physiology, Volume 241, Issue 2, February 2026.
Schematic diagram showing dose‐dependent effects of PA in oligodendrocyte precursor MO3.13 cells and rodent organotypic hippocampal and cerebellar slice cultures. High doses lead to cell death accompanied by mitochondrial impairment, whereas low doses activate the Nrf2 antioxidant response and exert neuroprotective effect while balancing mitochondrial ...
