Luteolin mitigates oxidative stress and multi-organ impairment in a propionic acid-induced rodent model of autism.

Background/objectives: Oxidative stress, organ impairments, and gastrointestinal abnormalities are the most common systemic dysfunctions that accompanied the neurodevelopmental condition, Autism Spectrum Disorder (ASD). Emerging evidence suggests that increased propionic acid (PPA) levels contribute to ASD pathophysiology through oxidative stress, neuroinflammation and disruption of the gut-liver-brain axis. Thanks to its strong anti-inflammatory and antioxidant potencies, luteolin, has shown to be promising in alleviating these effects.

Impact of GABA and nutritional supplements on neurochemical biomarkers in autism: a PPA rodent model study.

Background/objectives: Autism spectrum disorder (ASD) is associated with excitatory-inhibitory imbalance and oxidative stress. GABA, an inhibitory neurotransmitter, and related nutritional therapies are promising in restoring these imbalances. GABAergic deficits and glutamate excitotoxicity are two essential signaling pathways that could be addressed to treat autism, thus medications targeting these pathways are critical for treating behavioral symptoms.
