PSMα3 TFA

PSMα3 TFA is a peptide used to direct dendritic cells (DCs) towards a tolerogenic state, critical for DC vaccination approaches. It modulates human monocyte-derived DCs by disrupting maturation induced by TLR2 or TLR4, suppressing pro-inflammatory and anti-inflammatory cytokine secretion, and reducing antigen assimilation. Notably, PSMα3 TFA is a significant toxin secreted by highly virulent methicillin-resistant Staphylococcus aureus (MRSA) strains [1] [2].
