abstract
- Atrial natriuretic factor (ANF) is the first of a group of atrial natriuretic peptides (ANPs) discovered since 1981. This group of peptides is thought to have an important role in sodium homeostasis and regulation of fluid volume. Although the role of ANF in cardiovascular and renal disorders is under investigation, the specific signaling involvement that ANF may have in the central nervous system is still unexplored. To date, ANF has not as yet been associated with a given functional area in the brain, nor has it been shown to be linked to any particular psychopathology. Neuropharmacology research of these peptides and their drug manipulation is needed to advance our knowledge of the possible role of ANF in psychiatry beyond the current level of speculation.
