There is a slowly growing body of support for certain hallucinogenic serotonin-like molecules supporting cognitive gains, antidepressant effects and changes in brain areas related to attention, self-referential thought, and internal mentation. These molecules are present in Virola Ayahuasca and used in traditional native South American medicine.
Here researchers found that in silico systems biology analyses support 5- MeO-DMT’s anti-inflammatory effects and reveal a modulation of proteins associated with the formation of dendritic spines, including proteins involved in cellular protrusion formation, microtubule dynamics and cytoskeletal reorganization. Proteins involved in long-term potentiation were modulated in a complex manner, with significant increases in the levels of NMDAR, CaMKII and CREB, but a reduction of PKA and PKC levels. These results offer possible mechanistic insights into the neuropsychological changes caused by the ingestion of substances rich in dimethyltryptamines: Vanja Dakic, Juliana Minardi Nascimento, Rafaela Costa Sartore, Renata de Moraes Maciel, Draulio B. de Araujo, Sidarta Ribeiro, Daniel Martins-de-Souza , Stevens Rehen.
