Résumé
Substantial evidence from preclinical models of pain suggests that basal and noxious nociceptive sensitivity, as well as antinociceptive responses to drugs, show significant heritability. Individual differences to these responses have been observed across species from rodents to humans. The use of closely related C57BL/6 inbred mouse substrains can facilitate gene mapping of acute nociceptive behaviors in preclinical pain models. In this study, we investigated behavioral differences between C57BL/6 J (B6 J) and C57BL/6 N (B6 N) substrains in the formalin test, a widely used tonic inflammatory pain model, using a battery of pain-related phenotypes, including reflexive tests, nesting, voluntary wheel running, sucrose preference and anxiety-like behavior in the light/dark test at two different time points (1-h and 24-h). Our results show that these substrains did not differ in reflexive thermal and mechanical responses at the 1-h time point. However, B6 N substrain mice showed increased sensitivity to spontaneous pain-like behaviors. In addition, B6 N substrain continued to show higher levels of mechanical hypersensitivity compared to controls at 24-h. indicating that mechanical hypersensitivity is a more persistent pain-related phenotype induced by formalin. Finally, no sex differences were observed in our outcome measures. Our results provide a comprehensive behavioral testing paradigm in response to an inflammatory agent for future mouse genetic studies in pain.
