This hypothesis-building article (2017) proposes that psychedelics such as psilocybin and ketamine exert antidepressant effects by restoring balance to the fibrinolytic system, a network of enzymes in the bloodstream that prevent blood clots from growing and reopen vessels closed by thrombosis. The authors postulate that psilocybin decreases coagulation promoting factors, neuroinflammation, and fibrin deposition in the brain, and restores the 5-HT2a receptor to pre-stress levels.
