STAT3 and systemic lupus erythematosus: In order to further elucidate the possible molecular mechanisms involved in the immunomodulatory effects of an OLA-enriched diet, we evaluated the protein expression of several signaling pathways implicated in SLE pathogenesis: MAPKs, the Nrf-2/HO-1 axis, JAK3/STAT3 phosphorylation, and the NF-κB signaling pathways.
