Dysregulation of the behavioral and neuroendocrine responses to stressors can have severe psychological and physiological consequences. There is much evidence suggesting that inappropriate regulation, disproportional intensity, or chronic and/or irreversible activation of the stress response is linked to the etiology and pathophysiology of anxiety disorders and depression. We are employing integrated molecular, biochemical, pharmacological, physiological and behavioral methods, converging on the generation of genetic mouse models as an in vivo tool, in order to study the central pathways and molecular mechanisms mediating the organism‘s stress response and the related psychopathologies. Defining the contributions of known and novel gene products to the maintenance of stress-linked homeostasis may improve our ability to design therapeutic interventions for, and thus manage, stress-related psychiatric disorders.
