Scutellarin Attenuates Pro-Inflammatory Foam Cell Formation and Facilitates M2 Polarization in Microglia during Copper Homeostasis Imbalance via the MAPK Signaling Pathway

Here, we demonstrated that copper can induce microglia to damage myelinating cells, with the key mechanism involving the phosphorylation of p38 MAPK. Scutellarin partially reversed the positive effects of copper on promoting microglial M1 polarization, lipid deposition, and lipid oxidation by mediating the p38 MAPK signaling pathway. Taken together, these results suggest that scutellarin may be a promising drug for the treatment of demyelinating diseases such as multiple sclerosis.
