TAR-DNA binding protein 43 in Pick disease

Stefanie H Freeman et al. J Neuropathol Exp Neurol. 2008 Jan.

Abstract

Pick disease (PiD) is a frontotemporal dementia characterized by frontal and temporal atrophy, neuronal loss, gliosis, ballooned neurons that are positive for alpha-B crystallin and neurofilament, and the presence of tau- and ubiquitin-positive Pick bodies. TAR-DNA binding protein 43 (TDP-43) has been found to be a component of ubiquitinated inclusions in other neurodegenerative diseases, including frontotemporal lobar degeneration with ubiquitinated inclusions and amyotrophic lateral sclerosis. Fifteen cases of PiD were examined using immunohistochemical methods, and 5 cases with both Pick bodies and smaller intracytoplasmic inclusions that showed staining for ubiquitin, tau, and TDP-43 were observed. The presence of TDP-43 inclusions in PiD suggests that TDP-43 accumulation may be an important component of many neurodegenerative diseases, and that its presence in only some cases of PiD may indicate different pathways of disease development.
