Schizophrenia: A unique translational opportunity in behavioral neuroendocrinology

Schizophrenia is a complex and debilitating neuropsychiatric disease in which both environmental and genetic factors contribute to the pathophysiology of the disease. Epidemiological data point to the importance of the prenatal period in the genesis of schizophrenia and suggest that environmental factors, such as stress and hormones of the hypothalamic-pituitary-adrenal axis, may establish a vulnerability to the disease. Unfortunately, the exact cause of this neurodevelopmental disease is unclear. In this review, data on the importance of gestational stress exposure to the etiology of schizophrenia-like behavioral, endocrine and molecular phenotypes will be presented and differences will be highlighted between the preparations that are commonly used in most laboratory investigations.
