Hypothesis
Can Kunitz-domain 1 of human tissue factor pathway inhibitor-2 protect against the toxicity of 2-chloroethyl ethyl sulfide?
Conclusion
Wild-type Kunitz-domain 1 can significantly improve wound healing in cells exposed to a chemical warfare agent.
Supporting Evidence
- Wild-type Kunitz-domain 1 inhibited the activity of trypsin and plasmin.
- Wild-type Kunitz-domain 1 significantly improved wound healing of unexposed and 2-chloroethyl ethyl sulfide–exposed cells.
- R24Q Kunitz-domain 1 promoted wound closure but to a much lesser degree.
Takeaway
This study shows that a specific protein can help heal skin wounds caused by a harmful chemical.
Methodology
The study involved expressing and purifying recombinant proteins and testing their effects in an in vitro human epidermal keratinocyte cell wounding assay.
