Pattern of NF-κB activity in the lesion center and adjacent cranial and caudal areas at 1, 3, 7, 10, 14, and 28 days after SCI, presented as a number of NF-kB p65⁺ nuclei per square millimeter (a). The most pronounced levels of NF-kB p65 nuclear translocation were detected in the lesion centers at day 28 after SCI and were found to be significantly higher than all other time points except for values from day 3 after SCI. In addition, NF-κB-related transcription was significantly higher 3 days after injury when compared with 1-day interval (b). Data are shown as the mean and SEM, *p ≤ 0.05, **p ≤ 0.01
