Lower density of calretinin-immunopositive neurons in the putamen of subjects with schizophrenia.

ABSTRACT: Schizophrenia (SCH) is a chronic and serious mental illness which puts an enormous burden on the individual, families, and society. It is well established that altered dopamine signaling and excitatory-inhibitory imbalance contributes to the symptoms of schizophrenia. Recent neuroimaging and histological studies suggest that the striatum is a key area involved in SCH, however, our knowledge of how specific cell neuronal subtypes of certain subcortical structures may be impaired is incomplete. To this date, no detailed investigation of the putamen has ever been published regarding neuroanatomical changes in SCH. Here we tested whether the density of calretinin immunopositive (CR+) neurons and DARPP32+ neurons is altered in the putamen of patients with SCH. We used immunohistochemistry to re
