Effects of single-dose antipurinergic therapy on behavioral and molecular alterations in the valproic acid-induced animal model of autism

ASD is characterized by deficits in sociability, sensory processing and by stereotypical behaviors. Animals prenatally exposed to VPA showed purinergic-related molecular alterations. Suramin rescued ASD-like impairments in the VPA-animal model.

Abnormal empathy-like pro-social behaviour in the valproic acid model of autism spectrum disorder

Individuals with ASD can present deficits in empathy-dependent features. Empathy is a complex social manifestation recently described in rodents. VPA-induced animal model of ASD shows abnormal empathy-like pro-social behaviour. Early tracking analysis provide strong correlation with the test outcomes.

Reduced CD4 T Lymphocytes in Lymph Nodes of the Mouse Model of Autism Induced by Valproic Acid

We aimed to evaluate possible alterations of T cell pools in the lymphoid organs of an animal model of autism induced by valproic acid (VPA). We observed that the prenatal exposure to VPA induced a reduction in the numbers of CD3+CD4+ T cells in their lymph nodes when compared to the control animals. This was specific since it was not seen in the thymus or spleen. The consistent decrease in the number of CD4+ T cells in subcutaneous lymph nodes of mice from the animal model of autism may be related to the allergic symptoms frequently observed in ASD.

Resveratrol Prevents Cellular and Behavioral Sensory Alterations in the Animal Model of Autism Induced by Valproic Acid

This study aimed to analyze the effects of prenatal exposure to VPA, as well as possible preventive effects of RSV, on sensory behavior, the localization of GABAergic parvalbumin (PV+) neurons in sensory brain regions and the expression of proteins of excitatory and inhibitory synapses. Our data showed for the first time an altered localization of PV+-neurons in primary sensory cortex and amygdala. We also showed a reduced level of gephyrin in the primary somatosensory area (PSSA) of VPA animals. The treatment with RSV prevented all the aforementioned alterations triggered by VPA.

Data on social transmission of food preference in a model of autism induced by valproic acid and translational analysis of circulating microRNA

This article contains data of Social Transmission of Food Preference in an animal model of autism and the evaluation of a set of microRNA analyzed in autistic patients and animal model of autism. We identified 13 microRNA with similar levels among rodents' experimental groups, as well as 11 microRNA with no alterations between autistic and control subjects. Further evaluation of mechanisms of VPA and RSV actions on behavioral and molecular alterations can shed light in important biomarkers and etiological triggers of autistic spectrum disorders.

Behavioral alterations in autism model induced by valproic acid and translational analysis of circulating microRNA

In this work, we analyzed the effects of resveratrol (an antioxidant and anti-inflammatory molecule) on behavioral alterations of the VPA model of autism, as well as the levels of circulating miRNA. We also evaluated the same set of miRNA in autistic patients. Rats of the VPA model of autism showed reduced total reciprocal social interaction, prevented by prenatal treatment with resveratrol (RSV). The levels of miR134–5p and miR138–5p increased in autistic patients. Interestingly, miR134–5p is also upregulated in animals of the VPA model, which is prevented by RSV.
