Regulatory effect of curcumin on CD40:CD40L interaction and therapeutic implications

Natural compounds have garnered significant attention as potential therapeutic agents due to their inherent properties. Their notable qualities, including safety, efficacy, favorable pharmacokinetic properties, and heightened effectiveness against certain diseases, particularly inflammatory conditions, make them particularly appealing. Among these compounds, curcumin has attracted considerable interest for its unique therapeutic properties and has therefore been extensively studied as a potential therapeutic agent for treating various diseases. Curcumin exhibits diverse anti-inflammatory, antioxidant, and antimicrobial effects. Curcumin's immune system regulatory ability has made it a promising compound for treatment of various inflammatory diseases, such as psoriasis, atherosclerosis, asthma, colitis, IBD, and arthritis. Among the signaling pathways implicated in these conditions, the CD40 receptor together with its ligand, CD40L, are recognized as central players. Studies have demonstrated that the interaction between CD40 and CD40L interaction acts as the primary mediator of the immune response in inflammatory diseases. Numerous studies have explored the impact of curcumin on the CD40:CD40L pathway, highlighting its regulatory effects on this inflammatory pathway and its potential therapeutic use in related inflammatory conditions. In this review, we will consider the evidence concerning curcumin's modulatory effects in inflammatory disease and its potential therapeutic role in regulating the CD40: CD40L pathway.
