SA-4-1BBL and monophosphoryl lipid A constitute an efficacious combination adjuvant for cancer vaccines.
Vaccines based on tumor-associated antigens (TAA) have limited therapeutic efficacy due to their weak immunogenic nature and the various immune evasion mechanisms active in advanced tumors. In an effort to overcome these limitations, we evaluated a combination of the T-cell costimulatory molecule SA-4-1BBL with the TLR4 agonist monophosphoryl lipid A (MPL) as a novel vaccine adjuvant system. In...
متن کاملThe adjuvant monophosphoryl lipid A increases the function of antigen-presenting cells.
The induction of immune responses in vivo is typically performed with antigens administered in external adjuvants, like alum, complete Freund's adjuvant, LPS and, more recently, monophosphoryl lipid A (MPL). However, the role of the adjuvant is still poorly defined. The aim of this study was to test whether the MPL affects the function of antigen-presenting cells (APC) in vitro and in vivo. Ant...
متن کاملMonophosphoryl Lipid a as an adjuvant for immune therapy? A detailed in vitro comparison to LPS
Monophosphoryl lipid A (MPL) is a non-toxic TLR4 ligand, derived from Salmonella minnesota R595 (Re) lipopolysaccharide (LPS) by chemical modification. It is clinically used as an adjuvant for cancer treatment (Fendrix, Ceravix) and allergen specific immunotherapy (Pollinex Quattro, ORALVAC). Nevertheless, reports on the mechanism of adjuvant activity are limited. The aim of this study was to c...
متن کاملRole of innate immune factors in the adjuvant activity of monophosphoryl lipid A.
Monophosphoryl lipid A (MPL) is a nontoxic derivative of lipopolysaccharide (LPS) that exhibits adjuvant properties similar to those of the parent LPS molecule. However, the mechanism by which MPL initiates its immunostimulatory properties remains unclear. Due to the involvement of Toll-like receptors in recognizing and transducing intracellular signals in response to LPS, the aim of the presen...
