Therapeutic Efficacy of a Synthetic Brain-Targeted HS Donor Cross-Linked Nanomicelle in Autism Spectrum Disorder Rats through Aerobic Glycolysis.

Autism spectrum disorder (ASD) is characterized by cognitive inflexibility and social deficits, with a notably limited range of brain-targeted medications, particularly in the field of nanomedicine. Herein, we introduce the brain-targeted HS donor cross-linked nanomicelle, named mannose-PEG600-lipoic acid (Man-LA). Man-LA demonstrates enhanced stability and precise brain delivery by interacting with glucose transporter 1 (GLUT1) in astrocytes, facilitating a gradual release of HS that is modulated by glutathione (GSH).

Methods: The LARS was presoaked with 5, 2.5 or 1.

Augmentation of Endogenous 2-Arachidonoylglycerol Mitigates Autistic Behaviors of BTBR Mice.

The lipid-based endocannabinoid (eCB) system regulates a host of developmental, physiological, and pathological processes in the mammalian brain, and recent studies have suggested that dysfunction of eCB system may contribute to the neuropathology of autism spectrum disorder (ASD). However, specific contributions to ASD-related developmental, cognitive, and behavioral phenotypes remain largely unexplored. The current study was designed to investigate if enhancing eCB signaling by blocking 2-arachidonoylglycerol (2-AG) hydrolase can mitigate ASD-like behaviors in a mouse model, and if such effects are associated with suppression of inflammatory signaling, oxidative stress, or neuronal apoptosis.
