Lifelong exposure to n-3 PUFA deficiency leads to anxiety-like profile in male and female adolescent rats: Impact on spleen-brain axis.

Low consumption of n-3 polyunsaturated fatty acids (PUFA) during the developmental period has been increasingly associated with an increased risk of depressive-like symptoms in both male and female sexes. Therefore, here we performed behavioral and biochemical quantifications in adolescent rats to evaluate possible sex-driven differences in the development of anxiety-like disorders related to life-long n-3 PUFA low intake. Male and female adolescent rats fed for their entire life with n-3 PUFA poor diet showed an anxiety-like profile compared to n6/n-3 PUFA balanced diet.

Sex differences in the BTBR idiopathic mouse model of autism spectrum disorders: Behavioural and redox-related hippocampal alterations.

Autism spectrum disorders (ASD) are highly heterogeneous neurodevelopmental diseases. Epidemiological data report that males have been diagnosed with autism more frequently than females. However, recent studies hypothesize that females' low incidence might be underestimated due to standard clinical measures of ASD behavioural symptoms, mostly derived from males.

Amygdalar neurotransmission alterations in the BTBR mice model of idiopathic autism.

Autism Spectrum Disorders (ASD) are principally diagnosed by three core behavioural symptoms, such as stereotyped repertoire, communication impairments and social dysfunctions. This complex pathology has been linked to abnormalities of corticostriatal and limbic circuits. Despite experimental efforts in elucidating the molecular mechanisms behind these abnormalities, a clear etiopathogenic hypothesis is still lacking.
