Research Abstract

It is essential to develop effective immunoadjuvants for tumor immunotherapy. We created new adjuvants based on the structure of mycoplasmal lipopeptide, which is a toll-like receptor (TLR) 2 ligand. Adjuvant engineering, substituting a functional motif for bacterial origin sequence of lipopeptide, is a novel drug design strategy. Here, we report the characterization of a new TLR2 ligand with complexation capability.
