Monophosphoryl lipid A (MPLA), a vaccine adjuvant, can render endothelial cells tolerant to subsequent challenge by lipopolysaccharide (LPS). Tolerance results in impaired MyD88-dependent signalling, leading to reduced cytokine production. The present study highlights the potential use of immunomodulators to prevent infection-mediated endothelial dysfunction.
