Psoriasis is a chronic inflammatory skin condition characterized by erythematous plaques with white scales. Its pathogenesis is closely linked to oxidative stress and an imbalance in Th1/Th2 immune responses. Current treatments for psoriasis, such as topical agents, systemic therapies and phototherapy, frequently fail to achieve complete remission in clinical settings. Monomethyl fumarate (MMF), which has been approved by the US Food and Drug Administration in 2020 for multiple sclerosis, has demonstrated efficacy in psoriasis management. Additionally, our previous studies have identified aluminum ions as beneficial in psoriasis treatment. This present study investigates the combined therapeutic effects of MMF and aluminum ions and observed that the combination treatment achieves superior efficacy compared to either treatment alone in a psoriasis mouse model through the modulation of the Nrf2/NF-κB signaling pathway, as demonstrated in cellular models. The combination first activates Nrf2 nuclear translocation and induces antioxidant gene expression, followed by the inhibition of NF-κB nuclear translocation and phosphorylation, which reduces Th1 cytokine production and cellular chemotaxis. Concurrently, the treatment elevates Th2 cytokine secretion, thereby increasing the anti-inflammatory response in HaCaT cells. Overall, these findings support the MMF and aluminum ions combination (MMFAL) as a potential therapeutic strategy for psoriasis, effectively diminishing inflammation and oxidative stress.
