Description
MPL adjuvant is a chemically modified derivative of lipopolysaccharide that displays greatly reduced toxicity while maintaining most of the immunostimulatory activity of lipopolysaccharide. It has been used extensively in clinical trials as a component in prophylactic and therapeutic vaccines targeting infectious disease, cancer and allergies. MPL is a potent stimulator of T cell and antibody responses. MPL has been shown to be capable of binding and activating Tolllike receptor-4 (TLR-4), present on key antigen-presenting cells, which play an important role in the induction of the innate and subsequent adaptive immune responses. Recent observations suggest that MPL, directly affects adaptive immune responses via specific interactions with B cells. MPL is the first and only TLR ligand in licensed human vaccines, in the form of AS04. MPL is licensed in Europe for allergy treatment Pollinex Quattro. With over 33,000 doses administered to date, MPL adjuvant has emerged as a safe and effective vaccine adjuvant.
