Detection of IκB-α and IL-1β mRNAs on activated glial cells in Sp5C with in situ hybridization. Although increases in Iba-1 and GFAP immunoreactivities were found in Sp5C areas 14 days after the ligation on the mental nerve (arrows), no positive hybridization signals for IκB-α or IL-1β mRNAs were detected in these regions (lower panels). Scale bar: 500 μm.
