Decoy peptides in some fields such as virus infection (for trapping viruses through binding to the surface ligands) have been studied; however, for CVDs only a few decoy peptides such as ΨPLB-SE/ΨPLB-TE decoy, chemokine decoy receptor D6, and decoy receptor OPG have been examined to date and more studies are needed. Here, TNFRSF11B is linked to viral infectious disease.
