Figure 4. C5−/− and C5aR1−/− mice have accelerated wound healing phenotypes similar to C3−/− mice.
To examine the involvement of downstream complement molecules in wound healing, we wounded A) C5−/− mice and B) C5aR1−/− mice, and compared the rate of surface area healing to that of complement-sufficient animals over time. The data are expressed as percentage areas compared to the initial wounded area (100%) on the Y-axis. We observed that both C5−/− mice and C5aR1−/− mice exhibited accelerated healing over the first days of the process, suggesting that C5a is involved in the inflammatory stage of healing.
