Depression and anxiety disorders cause the greatest global disability in terms of impact on the individual, family, and society at large. The etiology of these disorders is multifactorial and includes complex interactions between genetic and environmental risk factors. This chapter reviews preclinical studies assessing the importance of gene–environment (G×E) interaction. Specifically, we focus on G×E studies assessing the roles of the hypothalamic–pituitary–adrenal (HPA) axis, serotonergic system, GABAergic system, and brain-derived neurotrophic factor (BDNF) system. Finally, novel candidate target genes for the treatment of depression and anxiety disorders are considered.

Keywords:   depression, anxiety, gene, environment, HPA, GABA, BDNF, 5-HT
