In a mouse model of inflammation-induced depression, S-ketamine (S-KET) reduced depressive-like behaviors and lowered pro-inflammatory factors in the medial prefrontal cortex, while R-ketamine (R-KET) did not. S-KET bound directly to the protein SIRT2 at the Q167 residue, enhancing its interaction with NF-κB subunit p65, which reduced acetylation and suppressed pro-inflammatory gene expression. Experiments using RNA interference, a SIRT2 inhibitor (AK-7), and pharmacological blockade confirmed that SIRT2 is essential for these effects. The findings indicate that SIRT2 mediates the therapeutic actions of S-KET, suggesting a target for treating inflammation-associated depression.

Psychedelics such as psilocybin and MDMA show promise for treating anorexia nervosa by disrupting maladaptive neural circuits, enhancing cognitive flexibility, and facilitating emotional processing. Early studies report reductions in symptoms and improvements in psychological well-being, particularly for patients unresponsive to conventional therapies like cognitive-behavioral therapy and pharmacotherapy. However, further research is needed to establish long-term safety, efficacy, and clinical integration, and to address legal, ethical, and safety challenges.

Psychedelics like LSD, psilocybin, and MDMA may enhance pro-social behaviors in people with autism spectrum disorders by altering brain circuits involved in social cognition. The viewpoint discusses potential mechanisms underlying these effects, such as increased neuroplasticity and changes in serotonin receptor activity. While direct evidence in ASD populations is limited, the authors suggest that these compounds could offer new therapeutic avenues for improving social interaction and communication deficits. The paper calls for further research to explore the safety and efficacy of psychedelic-assisted therapy for autism, emphasizing the need for controlled clinical trials.

Classic psychedelics and the gut microbiome influence each other through 5-HT2A receptor signaling, neuroplasticity, and microbial metabolism. Psychedelics may alter the composition of gut bacteria, while the microbiome can affect how well these compounds work. The authors propose using microbiome-informed approaches, such as probiotics or dietary changes, to tailor and improve psychedelic treatments for mental health conditions.

Psychedelics can significantly enhance neuroplasticity, as evidenced by a study involving 100 participants. Participants experienced a remarkable 40% increase in synaptic plasticity markers after treatment. The effects were linked to improved neurotransmission and elevated levels of neurotrophic factors, essential for brain health. Long-term potentiation was notably enhanced, indicating potential for cognitive benefits. Additionally, the involvement of nicotinic acetylcholine receptors suggests a complex interplay in metaplasticity. This research highlights the transformative potential of psychedelics in psychology and neuroscience, paving the way for innovative therapeutic approaches.

Classic psychedelics like LSD, psilocybin, DMT, and mescaline, as well as the antidepressant ketamine, can cause lasting changes in brain function and behavior beyond their immediate effects. This review examines how these substances may influence epigenetic regulation—changes in gene activity that do not alter the DNA sequence itself—through mechanisms such as DNA methylation, histone modifications, and non-coding RNA dynamics. The authors propose that psychedelics also affect metabolic pathways, altering the availability of key molecules like acetyl-CoA and SAM, which in turn may impact gene expression and synaptic connectivity. Understanding these processes could help explain how short-term psychedelic exposure leads to sustained therapeutic benefits and guide the development of new treatments for neuropsychiatric conditions.

Classic serotonergic psychedelics like LSD, psilocybin, and DMT show promise for treating neuropsychiatric disorders but are limited by first-pass metabolism, erratic pharmacokinetics, and off-target effects. Advanced delivery systems—including transdermal and microneedle patches, intranasal sprays, sublingual films, and injectable formulations—along with molecular strategies such as prodrugs and selective receptor bias, bypass hepatic metabolism, enable precise control over onset and duration, and minimize peripheral activation. Preclinical and early clinical evidence indicates gains in bioavailability, half-life extension, and conversion of fleeting effects into manageable windows, offering a path to safer, patient-centered therapies despite regulatory and trial-design challenges.
