- Research studies analyzing mice is important for preliminary research, but they are not miniature humans.
- Before extrapolations to humans are made, studies must find all the differences between humans and mice (unlikely), study closer ancestors to humans (chimpanzees, unlikely due to social acceptance), or study humans!
Unfortunately, mice are not miniature humans and much of the results on mice is not transferable to humans. Recently, a study found mice appear more resistant to inflammation and infection compared to humans (Seok 2013). These results indicate studies looking at infection or inflammation (which has been correlated with many diseases) are not transferable.
Specifically, metabolic health is becoming more synonymous with inflammatory status. A recent study by Phillips (2013) looked at obese and nonobese people and concluded “inflammatory status is positively associated with metabolic health in obese and nonobese individuals”.
Health Research and Mice Conclusion
Once again, mice are cute, furry creatures which play a vital stepping stone in research. Unfortunately, extrapolating information from mice is hazardous. Our research takes us only so far, common sense and anecdotal experience often must bridge the gap between science and reality.
