Notes: Pam3CSK4 is a synthetic bacterial lipopeptide that binds to and acts as an agonist at toll-like receptor 2 (TLR2).{38691} It induces proliferation of isolated mouse spleen cells and activates lymphocytes at a concentration of 50 µg/ml.{38692} Pam3CSK4 is a potent immune adjuvant in mice, enhancing the response to antigen, as measured by IgM and IgG levels, when used at a dose of 200 µg/animal. It inhibits Th1 and Th2 responses, suppresses eosinophil infiltration, and induces CD4+ T cell apoptosis in a mouse model of allergic conjunctivitis.{38693} Pam3CSK4 (50 µg) decreases lesion size and parasite burden in genetically-resistant and -susceptible mice when administered with L. major to induce leishmaniasis.{38694} It also enhances Th1 responses and stimulates IL-17 production in the early phase of infection.
