Moreover, there is evidence indicating that HIV dementia is not a homogeneous entity and could partially reverse after treatment with zidovudine. The finding that impaired axonal flow, evidenced by \u03b2\u2010amyloid precursor protein immunoreactivity, could contribute to the neuropsychological deficits prompted the present study. Brains of patients with full\u2010blown acquired immunodeficiency syndrome (AIDS) were studied and findings compared with those of normal and abnormal control subjects. The presence of HIV\u20101 DNA was investigated by nested polymerase chain reaction; axonal abnormalities were detected by \u03b2\u2010amyloid precursor protein, ubiquitin immunohistochemistry, and silver staining. Accumulation of \u03b2\u2010amyloid precursor protein was observed in all the HIV encephalitis brains studied; the appearance of the immunostaining varied from globular structures to bundles of parallel formations. In 2 AIDS brains without pathological abnormalities, only the latter pattern was detected. The brains with trauma were strongly reactive with \u03b2\u2010amyloid precursor protein antibody and the different reactivity within them correlated with posttrauma survival, only globular structures being detected in the older cases. No correlation was found between the different pattern of \u03b2\u2010amyloid precursor protein reactivity and dementia in AIDS patients. These results show that widespread axonal injury is a constant feature in AIDS brains and suggest that it could play a role in the pathogenesis of the neuropsychological abnormalities of these patients.<\/jats:p>","DOI":"10.1002\/ana.410420108","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T15:02:27Z","timestamp":1104591747000},"page":"34-40","source":"Crossref","is-referenced-by-count":92,"title":["Accumulation of \u03b2\u2010amyloid precursor protein in HIV encephalitis: Relationship with neuropsychological abnormalities"],"prefix":"10.1002","volume":"42","author":[{"given":"Bruno","family":"Giometto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shu F.","family":"An","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mike","family":"Groves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomaso","family":"Scaravilli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennian F.","family":"Geddes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Miller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno","family":"Tavolato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew A.
