The synthetic immunomodulators muramyl dipeptide (MDP), thymopoietin pentapeptide (TP5), and CP-46,665 were examined for their effects on wound healing in mice. We found no differences in wound disruption strength between immunomodulator-treated animals and saline controls on days 11, 14, and 21. The only exception was with high-dose CP-46,665, which produced weakened wounds on day 14 (p < 0.05) and 21 (p < 0.01). CP-46,665 was further studied by injecting high and low doses 48 hours before or after wounding. No differences were seen for these groups compared to controls at 11 and 21 days. Finally, to stimulate a common clinical situation, mice were subjected to a 10% total body surface area (TBSA) burn to the right paraspinal region. Twenty-four hours later, a left paraspinal incision was performed with simultaneous injection of saline, Corynebacterium parvum (C. parvum), or low-dose TP-5, MDP, or CP-46,665. At 11 days, no detriment in wound healing was found for burned control or any of the immunomodulator-treated animals except in the C. parvum-treated mice, with significantly weakened skin strips (p < 0.001). While C. parvum may be detrimental to wound healing, the synthetic modulators tested appear to have little effect on wound healing.
