Corticotropin-releasing factor inhibits maternal aggression in mice.
Lactating females that fiercely protect offspring exhibit decreased fear and anxiety. The authors tested whether decreased corticotropin-releasing factor (CRF), an activator of fear and anxiety, plays a functional role in maternal aggression. Intracerebroventricular (icv) injections of CRF (1.0 and 0.2 microg, but not 0.02 microg) significantly inhibited maternal aggression but not other matern...
متن کاملIncreased depression-like behaviors in corticotropin-releasing factor receptor-2-deficient mice: sexually dichotomous responses.
Depressive disorders affect nearly 19 million American adults, making depression and the susceptibility for developing depression a critical focus of mental health research today. Females are twice as likely to develop depression as males. Stress is a known risk factor for developing depression, and recent hypotheses suggest an involvement of an overactive stress axis. As mediators of the stres...
متن کاملAltered anxiety and weight gain in corticotropin-releasing hormone-binding protein-deficient mice.
Corticotropin-releasing hormone (CRH) is widely recognized as the primary mediator of the neuroendocrine and behavioral responses to stress, including stress-induced anxiety. The biological activity of CRH and other mammalian CRH-like peptides, such as urocortin, may be modulated by CRH-binding protein (CRH-BP). To assess directly the CRH-BP function, we created a mouse model of CRH-BP deficien...
متن کاملCorticotropin Releasing Factor Receptor 1–Deficient Mice Display Decreased Anxiety, Impaired Stress Response, and Aberrant Neuroendocrine Development
Corticotropin releasing factor (CRF) is a major integrator of adaptive responses to stress. Two biochemically and pharmacologically distinct CRF receptor subtypes (CRFR1 and CRFR2) have been described. We have generated mice null for the CRFR1 gene to elucidate the specific developmental and physiological roles of CRF receptor mediated pathways. Behavioral analyses revealed that mice lacking CR...
متن کاملDecoding Corticotropin-Releasing Factor Receptor Type 1 Crystal Structures
The structural analysis of class B G protein-coupled receptors (GPCR), cell surface proteins responding to peptide hormones, has until recently been restricted to the extracellular domain (ECD). Corticotropin-releasing factor receptor type 1 (CRF1R) is a class B receptor mediating stress response and also considered a drug target for depression and anxiety. Here we report the crystal structure ...
