af

Although the molecular targets of classic and dissociative psychedelics differ (5HT and NMDA receptors, respectively), their plasticity promoting properties are similar and are known to activate TrkB, mTOR, and 5HT_(2A) signaling pathways, suggesting that these key signaling hubs may serve as potential targets for the development of "psychoplastogens," fast-acting antidepressants, and anxiolytics (Ly et al., 2018).

2018, Tanya Calvey, Fleur M. Howells, “Chapter 1: An Introduction to Psychedelic Neuroscience”, in Tanya Calvey, editor, Psychedelic Neuroscience, Elsevier (Academic Press), page 5:

The fact that LSD, psilocybin, and so forth act as psychoplastogens—agents that increase the plasticity of the mind—is part of what explains their therapeutic effects (Ly et al. 2018, Olson 2018).
