The effect of TLR4 signaling deficiency on sensory and motor deficits/ recovery in L31 mice. In the prevention paradigm (ad), a compared to mice in the vehicle group, paw withdrawal thresholds assessed using von Frey test maintained to similar level of baseline for mice in treated group, indicating that TAK 242 prevented disease associated numbness/ mechanical hyposensitivity. b Thermal sensitivity examined by acetone test was also normal in treated mice. c Quantitative data from grip strength showed that muscle strength was greater in treated group compared to vehicle group. d Clinical scores showed no appearance of neurological symptoms such as tail weakness and weakness of hind limb in treated group. In the reversal paradigm, treatment started between D17 post-PSNL when sensory and motor deficits were established (eh). e TAK 242 reversed mechanical hyposensitivity in treated group to pre-PSNL level. f Increased paw withdrawal duration in acetone test was equally reversed in treated mice. g Quantitative data from grip strength showed that the decreased muscle strength was reversed in treatment group, although not to baseline level. h Clinical score showed that the incidence of motor deficits was reduced in treated group. n = 10–12/group; *p < 0.05; **p < 0.01; ***p < 0.001
