ATP7A and Alzheimer disease: We did not detect a positive signal in any of these blast cases (Additional file 6: Figure S6), including Case 4 that survived 4 years after blast, despite the fact that all antibodies reacted with neurofibrillary tangles in control AD cases (data not shown) and all antibodies except MC1 stained tangles in an established case of dementia pugilistica (Additional file 6: Figure S6a-f).
