Naringin Alleviates Autistic‐Like Behaviors in BTBR Mice Through Cannabinoid Receptor Type 1‐Mediated Restoration of Hippocampal Neurogenesis

Year: 2025

Type: article

Abstract: BACKGROUND: Naringin, a flavanone glycoside (naringenin 7-O-neohesperidose), exhibits a broad range of pharmacological activities, including neuroprotection. However, its effects on autistic-like behavior have not been extensively studied. METHODS: In this investigation, we utilized the autistic BTBR T + tf/J (BTBR) mice to conduct behavioral tests assessing autistic-like phenotypes. We evaluated hippocampal neurogenesis through immunofluorescence and employed molecular biological techniques, along with RNA sequencing, to elucidate the underlying molecular mechanisms. RESULTS: Our findings revealed that the administration of naringin alleviated autism-associated behaviors in BTBR mice. RNA sequencing analysis indicated that naringin facilitated the recovery of impaired hippocampal neurogenesis in these mice, as evidenced by an increase in doublecortin (DCX)-positive cells and neuronal progenitor cells (NPCs) in the dentate gyrus (DG). Furthermore, we confirmed that the cannabinoid receptor type-1 (CB1) plays a role in the therapeutic effects of naringin. CONCLUSIONS: This research highlights the potential of naringin as a promising treatment option for autism spectrum disorder (ASD) and suggests that targeting hippocampal neurogenesis through the CB1 receptor may be an effective strategy.
