Dysfunctioning of corticotropin-releasing factor (CRF) and its receptors (CRF(1) and CRF(2)) has been linked to the development of stress-related disorders, such as affective disorders and drug abuse.
As mediators of the stress response, corticotropin-releasing factor (CRF) and its receptors (CRFR1 and CRFR2) have been implicated in the propensity for developing stress-related mood disorders.
Corticotropin-releasing hormone receptor-2 (CRHR2)-deficient mice display a stress-sensitive and anxiety-like phenotype suggesting that the CRHR2 is a plausible functional candidate gene influencing the reactivity of the HPA axis and therefore the liability to develop affective disorders.
