The serotonergic psychedelic N,N-dimethyltryptamine (DMT) produces rapid antidepressant effects in preclinical and early clinical studies. Therapeutic benefits have been linked to sustained neural plasticity, including adult neurogenesis in rodents. Whether brief DMT exposure engages proliferative responses in human neural stem cells (NSCs) remains unresolved. Using human iPSC-derived NSCs, we...

Psychedelics, recognized for their impact on perception, are resurging as promising treatments with rapid onset for mood and substance use disorders. Despite increasing evidence from clinical trials, questions persist about the cellular and molecular mechanisms and their precise correlation with treatment outcomes. Murine neurons and immortalized non-neural cell lines harboring overexpressed...

Abstract Harmine is a β-carboline found in Banisteriopsis caapi , a constituent of ayahuasca brew. Ayahuasca is consumed as a beverage in native Americans’ sacred rituals and in religious ceremonies in Brazil. Throughout the years, the beneficial effects of ayahuasca to improve mental health and life quality have been reported, which propelled the investigation of its therapeutic potential to...

Abstract Psychedelic agonists of serotonin receptors induce neural plasticity and synaptogenesis, but their potential to enhance learning remains uncharted. Here we show that a single dose of d-LSD, a potent serotonergic agonist, increased novel object preference in young and adult rats several days after treatment. d-LSD alone did not increase preference in old animals, but could rescue it to...
