Corticotropin-releasing factor, neuroplasticity (sensitization), and alcoholism.
S ensitization is a ubiquitous biological phenomenon that has a role in the neuroadaptation of many different functions, from learning and memory to stress responsivity. Historically, a specific form of sensitization termed psychomotor sensitization (mistermed in my view as ‘‘behavioral sensitization’’) is induced by repeated administration of drugs of abuse and has been linked to the neuroadap...
متن کاملAlcoholism: allostasis and beyond.
Alcoholism is a chronic relapsing disorder characterized by compulsive drinking, loss of control over intake, and impaired social and occupational function. Animal models have been developed for various stages of the alcohol addiction cycle with a focus on the motivational effects of withdrawal, craving, and protracted abstinence. A conceptual framework focused on allostatic changes in reward f...
متن کاملCorticotropin-releasing Factor
Introduction Immunoreactivity similar to that of corticotropin-releasing factor (CRF) is found in regions of the central nervous system that modulate autonomic responses, including gastrointestinal functions. We examined the central nervous system effects of ovine CRF on gastric acid secretion in conscious dogs. Male beagle dogs (11-13 kg) were fitted with chronic intracerebroventricular cannul...
متن کاملMolecular mechanisms of corticotropin-releasing factor receptor-induced calcium signaling.
The molecular mechanisms governing calcium signal transduction of corticotropin-releasing factor (CRF) receptors CRF(1) and CRF(2(a)) stably expressed in human embryonic kidney (HEK) 293 cells were investigated. Calcium signaling strictly depended on intracellular calcium sources, and this is the first study to establish a prominent contribution of the three major G-protein families to CRF rece...
متن کاملCorticotropin releasing factor in neuroplasticity.
Stress is among the strongest signals promoting neuroplasticity: Stress signals, indicating real or perceived danger, lead to alterations of neuronal function and often structure, designed to adapt to the changed conditions and promote survival. Corticotropin releasing factor (CRF) is expressed and released in several types of neuronal populations that are involved in cognition, emotion and the...
