Vasopressin 1b receptor knock-out impairs memory for temporal order.
Mice lacking a functional vasopressin 1b receptor (Avpr1b) display decreased levels of aggression and social memory. Here, we used Avpr1b-knock-out (Avpr1b(-/-)) mice to examine whether an abnormality of this receptor results in specific cognitive deficits in the domain of hippocampal function. Avpr1b(-/-) mice were deficient in sociability and in detecting social novelty, extending previous fi...
متن کاملHyperfunction of Muscarinic Receptor Maintains Long-Term Memory in 5-HT4 Receptor Knock-Out Mice
Patients suffering from dementia of Alzheimer's type express less serotonin 4 receptors (5-HTR(4)), but whether an absence of these receptors modifies learning and memory is unexplored. In the spatial version of the Morris water maze, we show that 5-HTR(4) knock-out (KO) and wild-type (WT) mice performed similarly for spatial learning, short- and long-term retention. Since 5-HTR(4) control mnes...
متن کاملSocial Context, Stress, Neuropsychiatric Disorders, and the Vasopressin 1b Receptor
The arginine vasopressin 1b receptor (Avpr1b) is involved in the modulation of a variety of behaviors and is an important part of the mammalian hormonal stress axis. The Avpr1b is prominent in hippocampal CA2 pyramidal cells and in the anterior pituitary corticotrophs. Decades of research on this receptor has demonstrated its importance to the modulation of social recognition memory, social for...
متن کاملGenetic vasopressin 1b receptor variance in overweight and diabetes mellitus
OBJECTIVE Recently, imbalance in the vasopressin (AVP) system, measured as elevated levels of copeptin (the C-terminal part of the AVP pro-hormone) in plasma, was linked to the development of abdominal obesity and diabetes mellitus (DM). Here, we aim to investigate if the genetic variation of the human AVP receptor 1b gene (AVPR1B) is associated with measures of obesity and DM. DESIGN Malmö D...
متن کاملImpaired Dendritic Development and Memory in Sorbs2 Knock-Out Mice.
UNLABELLED Intellectual disability is a common neurodevelopmental disorder characterized by impaired intellectual and adaptive functioning. Both environmental insults and genetic defects contribute to the etiology of intellectual disability. Copy number variations of SORBS2 have been linked to intellectual disability. However, the neurobiological function of SORBS2 in the brain is unknown. The ...
