Sex and hormonal status influence the anxiolytic-like effect of oxytocin in mice.

Anxiety and depression are highly prevalent psychiatric disorders, affecting approximately 18% of the United States population. Evidence indicates that central oxytocin mediates social cognition, social bonding, and social anxiety. Although it is well-established that oxytocin ameliorates social deficits, less is known about the therapeutic effects of oxytocin in non-social contexts.

The Partial M Muscarinic Cholinergic Receptor Agonist, CDD-0102A, Differentially Modulates Glutamate Efflux in Striatal Subregions during Stereotyped Motor Behavior in the BTBR Mouse Model of Autism.

The BTBR T Itpr3/J (BTBR) mouse displays elevated repetitive motor behaviors. Treatment with the partial M muscarinic receptor agonist, CDD-0102A, attenuates stereotyped motor behaviors in BTBR mice. The present experiment investigated whether CDD-0102A modifies changes in striatal glutamate concentrations during stereotyped motor behavior in BTBR and B6 mice.

Parallel learning and cognitive flexibility impairments between knockout mice and individuals with fragile X syndrome.

Introduction: Fragile X Syndrome (FXS) is a monogenic condition that leads to intellectual disability along with behavioral and learning difficulties. Among behavioral and learning difficulties, cognitive flexibility impairments are among the most commonly reported in FXS, which significantly impacts daily living. Despite the extensive use of the knockout (KO) mouse to understand molecular, synaptic and behavioral alterations related to FXS, there has been limited development of translational paradigms to understand cognitive flexibility that can be employed in both animal models and individuals with FXS to facilitate treatment development.

Prenatal stress and fluoxetine exposure in mice differentially affect repetitive behaviors and synaptic plasticity in adult male and female offspring.

Autism spectrum disorder (ASD) is characterized by social communication impairments with restricted and repetitive behaviors (RRBs). The increase in prevalence of ASD and the heterogeneity of symptom severity may arise from a complex interaction of environmental and genetic factors that alter synaptic plasticity. Maternal stress during pregnancy, which is linked to depression, may be one risk factor for an ASD phenotype in offspring.
