5-HT2A receptor activation is dispensable for psilocybin-induced fear extinction and neuroplasticity in mice.

Chinese medical journal September 15, 2026 Yingjie Du, Xiangting Zhao, Quan Chen et al.

Psilocybin facilitates fear extinction in rodents, but its clinical utility is hampered by 5-hydroxytryptamine (5-HT) 2A-receptor-mediated hallucinogenic effects. This study aimed to explore whether 5-HT2A receptor is obligatory for psilocybin's fear extinction and neuroplasticity effect. Male C57BL/6J mice underwent auditory-cue fear conditioning. Ketanserin (5-HT2A/2C antagonist) or MDL100907...

Psilocybin reduces fear memory and restores neuroplasticity in the hippocampus and medial prefrontal cortex.

J Psychopharmacol June 28, 2026 Yingjie Du, Xiangting Zhao, Yishan Yao et al.

BACKGROUND: Posttraumatic stress disorder (PTSD) and major depressive disorder are often comorbid in humans. Psilocybin reportedly has beneficial therapeutic effects on depression, possibly by promoting neuroplasticity. PTSD is associated with the dysregulation of neuroplasticity in the hippocampus and medial prefrontal cortex (mPFC). We hypothesized that psilocybin might reduce fear memory by...

Chronic Neuropathic Pain and Comorbid Depression Syndrome: From Neural Circuit Mechanisms to Treatment.

ACS Chemical Neuroscience July 3, 2024 Yue Zhang, Hui Ma, Yafan Bai et al. 25 citations

Chronic neuropathic pain and comorbid depression syndrome (CDS) is a major worldwide health problem that affects the quality of life of patients and imposes a tremendous socioeconomic burden. More than half of patients with chronic neuropathic pain also suffer from moderate or severe depression. Due to the complex pathogenesis of CDS, there are no effective therapeutic drugs available. The lack...

Psilocybin promotes neuroplasticity and induces rapid and sustained antidepressant-like effects in mice

Journal of Psychopharmacology April 28, 2024 Xiangting Zhao, Yingjie Du, Yishan Yao et al. 53 citations

Background: Psilocybin offers new hope for treating mood disorders due to its rapid and sustained antidepressant effects, as standard medications require weeks or months to exert their effects. However, the mechanisms underlying this action of psilocybin have not been identified. Aims: To investigate whether psilocybin has rapid and sustained antidepressant-like effects in mice and investigate...

Psilocybin facilitates fear extinction in mice by promoting hippocampal neuroplasticity.

Chinese medical journal December 20, 2023 Yingjie Du, Yunfeng Li, Xiangting Zhao et al. 71 citations

Posttraumatic stress disorder (PTSD) and depression are highly comorbid. Psilocybin exerts substantial therapeutic effects on depression by promoting neuroplasticity. Fear extinction is a key process in the mechanism of first-line exposure-based therapies for PTSD. We hypothesized that psilocybin would facilitate fear extinction by promoting hippocampal neuroplasticity. First, we assessed the...
