    basic FUNCTION
  • role in mediating the stress response and anxiety-related behaviour
  • plays an important role in the development of a functional HPA axis and in mediating behavioral changes associated with anxiety
  • play a facilitatory role in the non-clathrin-, non-caveolae-mediated endocytosis and intracellular signal transduction of urocortin
  • enhanced 5-HT2R signaling in neurons by promoting the recruitment of constitutively internalized 5-HT2R to the cell surface
  • critically controls behavioral adaptation to stress and is causally linked to emotional disorders
  • an imbalance between CRHR1-controlled anxiogenic glutamatergic and anxiolytic dopaminergic systems might lead to emotional disorders
  • role for this endogenous stress hormone in the resulting structural modifications and cognitive dysfunction
  • modulates early-life stress-programmed cognitive deficits
  • CRHR1 and CRHR2 differentially modulate the dendritic growth of hippocampal neurons

    ANIMAL & CELL MODELS
  • the medulla and the adrenal gland of mice lacking Crhr1 is atrophied and stress-induced release of adrenocorticotropic hormone (ACTH) and corticosterone is reduced
  • mice null for the CRFR1 gene display markedly reduced anxiety and fail to exhibit the characteristic hormonal response to stress
  • CRFR1-null mice have lower totalpancreatic islet numbers, consistent with a role for Crhr1 in the regulation of beta cell mass (Huising 2010)
  • constitutive Crhr1 knockout (KO, Crhr1KO) mice show reduced anxiety-related behavior
