Figure 3: Significant upregulation of MHC class I expression was found in the spinal cord of CCI and formalin-injected rats but weak expressed in CFA-injected rats ((a)–(d) Scale bar, 100 μm). MHC class I positive cells were colocalized with Iba-1 ((e) Scale bar, 30 μm). The intensity of MHC class I immunoreactivity was quantitatively compared among four groups (f). * , as compared with the naïve group.
