Figure 5. Behaviour responses of HomNav1.7I228M mutant mice to formalin and CFA injections.
(A-B) Formalin test. HomNav1.7I228M mutant mice and their control littermates show similar licking durations in Phase I (WT, 165.6 ± 33.4 s, n=5; HomNav1.7I228M, 154.6 ± 15.8 s, n=5) and Phase II (WT, 246.4 ± 24.2 s, n=5; HomNav1.7I228M, 253.4 ± 32.2 s, n=5) of the formalin test. (C-D) Thermal and mechanical sensitivity measured by Hargreaves test and von Frey test following intra-plantar CFA injection. No significant difference is seen between WT (n=11) and HomNav1.7I228M (n=12) groups.
