Research Abstract

We observed the role of DBZ (DISC1-binding zinc finger protein), a schizophrenia related molecule, in the development of inhibitory neurons. DBZ has been reported to be an important factor in brain plasticity and also in the development of schizophrenia. We found that DBZ regulated the development of basket cells, a morphologically defined class of parvalbumin (PV)-containing interneurons. We also found that DBZ regulated the level of mRNAs for the gamma-aminobutyric acid (GABA)-synthesizing enzyme GAD67.
These findings suggest that DBZ regulates the development of inhibitory neurons and brain plasticity, which may play an important role in schizophrenia.
