Psilocin, A Psychedelic Drug, Exerts Anticonvulsant Effects Against PTZ- and MES-Induced Seizures in Mice via 5-HT1A and CB1 Receptors: Involvement of Nitrergic, Opioidergic, and Kynurenine Pathways

Researchers tested psilocin, the active ingredient in magic mushrooms, and found it could reduce seizures in mice at low doses (3-5 mg/kg) without causing psychedelic effects. The anticonvulsant benefits were mediated through several brain pathways including serotonin, cannabinoid, opioid, and nitric oxide signaling systems. The effects persisted for at least 9 days after a single dose, suggesting psilocin may have potential as a new treatment for epilepsy, though human clinical trials are needed to confirm these findings.

The Role of Nitric Oxide in the Growth and Development of Schizophyllum commune Under Anaerobic Conditions

This research shows that nitric oxide (NO) acts like a chemical messenger that helps mushroom fungi grow and reproduce when oxygen is scarce. Scientists studied a fungus found deep below the ocean floor and discovered that NO helps the fungus extend its root-like structures, germinate spores, and even initiate the formation of fruiting bodies (the mushroom stage). When they blocked NO with chemicals, growth slowed down, but when they added extra NO, growth accelerated. This discovery could help us understand how fungi survive in extreme environments with little oxygen.

Nitric Oxide-Mediated Regulation of Chitinase Activity and Cadmium Sequestration in the Response of Schizophyllum commune to Cadmium Stress

Schizophyllum commune is an edible mushroom with health benefits, but cadmium pollution threatens both the fungus and human health. Researchers discovered that when exposed to cadmium, the mushroom produces a signaling molecule called nitric oxide that makes its cell wall enzymes more active, causing cadmium to accumulate in the cell wall and damaging the fungus. By controlling nitric oxide levels, scientists could potentially make these fungi more resistant to heavy metal pollution and safer for consumption.

Alternative oxidase gene induced by nitric oxide is involved in the regulation of ROS and enhances the resistance of Pleurotus ostreatus to heat stress

Oyster mushrooms are commonly grown in controlled facilities but struggle with high summer temperatures. This study found that a molecule called nitric oxide helps mushroom cells survive heat stress by activating a special protein called alternative oxidase (AOX), which reduces harmful molecules called reactive oxygen species. By understanding this mechanism, growers may be able to improve mushroom cultivation and yield during hot weather.
