Similarly, decoy peptides targeting specific receptors, like the Toll-IL-1R domain, have shown efficacy in inhibiting downstream signaling events, such as LPS-induced inflammationWhat are Peptide Decoys?. For example, a TAT-4BB decoy peptide has been shown to diminish inward current facilitation in nociceptive neurons, highlighting their potential in pain management. In some cases, decoy peptides can directly block protein interactions, as seen with agents that block protein recruitment to Toll-like Receptors (TLRs).

Beyond directly targeting pathological proteins, decoy peptides can also be designed to interfere with viral mechanisms.
