Psychological stress not only undermines quality of life for people with cancer but also fuels tumor growth. Emerging evidence from the nascent field of cancer neuroscience suggests that adrenergic signaling from direct tumor-neuron interactions drives cancer progression, resistance to treatment, and worse outcomes. Cancer neuroscientists are increasingly seeking to repurpose psychoactive...
Rapid-acting antidepressants like ketamine and serotonergic psychedelics show promise for treatment-resistant depression (TRD), but the molecular mechanisms that contribute to their therapeutic effects remain unclear. Induced pluripotent stem cells (iPSCs) offer a platform to model human cortical neurons and investigate drug effects in a human-relevant system. Here, iPSCs from individuals with...
Treatment-resistant depression (TRD) is associated with worse clinical outcomes and longer course of illness. However, TRD is more difficult to model in animal phenotypes, suggesting that other experimental and translational models must be considered to properly address and research novel therapeutics. Reelin, an endogenous glycoprotein downregulated in depression, has shown rapid...
Mescaline (3,4,5-trimethoxyphenethylamine) is a classic serotonergic psychedelic with a history of indigenous ceremonial use. There is renewed scientific interest in mescaline because of the potential psychiatric benefits of psychedelic-assisted therapy. Mescaline primarily exerts its psychoactive effects through serotonin-2A (5-HT 2A ) receptor agonism. There is a lack of controlled clinical...
