Synthetic. Selective agonist of TLR1/TLR2 complex. Cell permeable, water soluble synthetic cationic lipohexapeptide analog of the immunologically active N-terminal portion of bacterial lipoprotein that potently activates monocytes and macrophages. Potent and effective immune adjuvant. Exerts strong local response, enhances IgG2a and IgG1 titers and upregulates proinflammatory and Th1 cytokine genes. Potent activator of the proinflammatory transcription factor NF-kappaB. Activates/represses at least 140 genes involved in signal transduction and regulation of the immune response.
