Christoph Kellendonk, PhD

Dr. Kellendonk obtained his PhD in the laboratory of Günther Schütz at the German Cancer Research Center in Heidelberg where he studied the function of the glucocorticoid receptor. He then joined Eric Kandel's laboratory at Columbia University in New York as a post-doctoral research fellow where he became interested in using mouse genetics to study neuropsychiatric disorders. Since 2008 Dr. Kellendonk is an independent investigator in the Departments of Pharmacology and Psychiatry at Columbia University.

The Kellendonk laboratory uses mouse genetic tools in an effort to understand the biology that underlies cognitive and negative symptoms of schizophrenia. Schizophrenia is characterized by three symptom clusters: the cognitive, negative and positive symptoms. While the positive symptoms – which include disordered thought processes, hallucinations and delusions – are the most characteristic feature of the disorder, such symptoms are more difficult to model in the mouse. In contrast, cognitive and negative symptoms of the disorder – including deficits in working memory and motivation – have behavioral readouts in mice that are more homologous to humans. Cognitive and negative symptoms are poorly understood, difficult to treat and their severities are a better predictor for the long-term prognosis of patients than the degree of positive symptoms.

Our approach uses observations made in patients with schizophrenia (e.g. with brain imaging) and then seeks to “model” these observations as closely as possible in the mouse. This allows for establishing causality between a specific brain alteration and changes in behavior. Using this approach we hope to achieve three main goals:

1) To better understand the basic neuronal mechanisms that support cognitive and motivated behaviors

2) To inspire new studies in humans based on observations made in the mouse

3) To identify new treatment strategies for enhancing cognition and motivation
