The Effects of Psilocybin on Lipopolysaccharide-Induced Inflammation in THP-1 Human Macrophages
Bibliographic record
Abstract
Psilocybin, an innate compound produced by mushrooms belonging to the Psilocybe genus, is primarily known for its agonistic effects on the serotonin 5-HT2A receptor. This receptor’s functioning is involved in many neurological processes. In the context of this research, our primary aim was to comprehensively investigate the influence of psilocybin as a serotonin receptor agonist on the intricate cascade of events involved in THP-1 macrophages stimulated by lipopolysaccharide (LPS). THP-1 monocyte cells were subjected to differentiation into macrophages through a controlled incubation with phorbol 12-myristate 13-acetate (PMA). The next step involved the induction of an inflammatory response by exposing THP-1 macrophages to 500 ng/mL LPS for 4 h. Subsequently, we triggered the activation of the second phase of the NLRP3 inflammasome by introducing adenosine triphosphate (ATP) immediately following LPS stimulation. Our findings have revealed a dose-dependent inverse correlation between psilocybin exposure and the production of LPS-induced proinflammatory cytokines and proteins. Our work indicates that psilocybin likely mediates these responses by influencing key signaling pathways, including NF-κB, IL-6/TYK2/STAT3, and TYK2/STAT1.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
