[3] Psilocybe - microbewiki - Kenyon College Psilocin reacts agonistically with serotonin (5-hydroxytryptamine) type 2A (5-HT2A) receptors to produce a mystical-like hallucinatory effect [5,99] (Figure 5) due to induced frontal hyper-frontality [5], which in turn mediates its anti-depressant and anti-anxiety effects [15,68]. The dephosphorylated form of psilocybin (psilocin) is responsible for psychotropic effects in humans [17].

Most or nearly all species contain the psychedelic compounds psilocybin and psilocin . It is recommended that such patients who will be less likely to benefit from such treatment should be excluded from psychedelic therapy. Given the upward trend in psilocybin research in recent years, the industry can only further benefit from optimized synthesis methodologies. Please refer to the appropriate style manual or other sources if you have any questions. Following the elucidation of the biosynthetic pathway for the production of psilocybin in P. Cubensis in 2017 [151], bioengineering has led to the production of psilocybin in the filamentous fungi Aspergillus nidulans, with yields of up to 1.16 g/L [152].

In a 2000 review on the worldwide distribution of psilocybin mushrooms, Gastn Guzmn and colleagues considered these distributed among the following genera: Psilocybe (116species), Gymnopilus (14), Panaeolus (13), Copelandia (12), Pluteus (6) Inocybe (6), Pholiotina (4) and Galerina (1). Also characteristic of depression and schizophrenia is an alteration of serotonergic signalling [188]. This led to the formation of the psychedelic research unit, and eventually, the Center for Psychedelic and Conscious Research (John Hopkins University) in 2006, which has since published over eighty peer-reviewed articles on psychedelic research [103]. By the 1960s, over 40,000 individuals took part in psychedelic research studies, albeit with less rigorous clinical standards [101]. The FDAs recent approval of SPRAVATO, a ketamine analog developed by Johnson and Johnson for use in patients suffering from treatment-resistant depression, and the approval of breakthrough therapy statuses for psilocybin treatments for Major Depressive Disorder (MDD) by Compass Pathways Ltd. and the Usona Institute, is also expected to spur the growth of psychedelic research.
