We investigated the cyclin-dependent kinase (Cdk) 5 distribution pattern in diffuse Lewy body disease brains using immunohistochemistry. Cdk5 immunoreactivity was detected in both brainstem-type Lewy bodies (LBs) and cortical LBs. The number of Cdk5-positive LBs was less than that of ubiquitin- or alpha-synuclein-positive LBs, and more than that of phosphorylated neurofilament-positive LBs. Immunoelectron microscopy revealed Cdk5-immunolabeled granulo-filamentous components in LBs and LB-related neurites. These data suggest that Cdk5 may be associated with LB formation.
