Molecular hybridization modification improves the stability and immunomodulatory activity of TP5 peptide [PDF]

Frontiers in Immunology
Thymopentin (TP5) plays an important role in host immunomodulation, yet its bioavailability is significantly limited by its short half-life. YW12D is a peptide with strong stability but relatively weak immunoactivity.
