Immunohistochemical analysis of nuclear NF-κB in cells around primitive (a and c) and classical plaques (e and g) of one representative AD patient (AD 90/129 from NBB and one representative age-matched control 93/166 from NBB), (b, d, f, and g) corresponding DAPI image of plaques. Note the reduced nuclear NF-κB immunoreactivity (compare arrows of a and b with arrows of c and d and arrows of e and f with the ones of g and h) in both plaque types of AD patients in comparison to healthy controls. Scale bar, 50 μm.
