Use of PSMα3

PSMα3 is a peptide for manipulating DCs to become tolerogenic for DC vaccination strategies. PSMα3 penetrates and modulates human monocyte-derived DCs by altering the TLR2- or TLR4-induced maturation, inhibiting pro- and anti-inflammatory cytokine production and reducing antigen uptake. PSMα3 is an important toxin released by the most virulent strains of methicillin-resistant Staphylococcus aureus (MRSA)[1][2].
