We also verified the localization of UCP2 immunoreactivity in mitochondria by co-immunofluorescence staining with the mitochondrial membrane protein, COX IV (Figure 5E-H) of hippocampal CA3 neurons on the right side (Figure 5F), 24 h after KA-induced status epilepticus compared with sham-control (Figure 5E). Here, COX4I1 is linked to status epilepticus.
