Abstract

Purpose: During a pathological inflammation, macrophages are activated to produce accumulation of inflammatory mediators such as induced-cyclooxygenase-2 (COX-2), 15-lipoxygenase (15-LOX) and pro-inflammatory cytokines. Pathological inflammation is a significant problem in many chronic diseases. As a result, more research into natural remedies with anti-inflammatory potential is crucial. Since ancient times, psilocybin-containing mushrooms, also known as magic mushrooms, were used for mind healing and also to advance the quality of life. However, not much is known about their anti-inflammatory potential. This study aimed at investigating the anti-inflammatory effects of four psilocybin-containing mushrooms ( Panaeolus cyanescens, Psilocybe natalensis, Psilocybe cubensis and Psilocybe cubensis leucistic A+ strain ) from genus Panaeolus and Psilocybe for the first time in vitro on 15-LOX activity and also on lipopolysaccharide (LPS)-induced inflammation in human U937 macrophage cells. Methods: Mushrooms were grown and extracted with boiling hot water. Effects of the four water extracts on 15-LOX activity were determined. Confluent human U937 cells were differentiated with phorbol 12-myristate 13-acetate and treated with the hot-water extracts (25 and 50 μg/mL) 2 hours before being stimulated with 1 μg/mL LPS over 24 hours. Quercetin was used as a positive control. Control cells were differentiated but not LPS-induced nor treated. Tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-10 concentrations were measured. Levels of COX-2 and mitochondrial activity were also determined. Results: The four water extracts had poor 15-LOX inhibition activity with IC 50 > 250 μg/mL. Extracts were safe at the concentration studied and inhibited the LPS-induced production of pro-inflammatory mediators, TNF-α and IL-1β significantly and lowered IL-6 and COX-2 concentrations in treated human U937 macrophage cells. Water extracts also increased percentage viability of treated cells and levels of anti-inflammatory IL-10 non-significantly. Conclusion: The study suggested that the hot-water extracts of the four psilocybin-containing magic mushrooms have potential anti-inflammatory effects executed by down-regulating pro-inflammatory mediators.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
