Neuromodulators: acetylcholine, norepinephrine, epinephrine, vasopressin, histamine, arginine, serotonin, dopamine, autocrine agents, and $\beta$-endorphin.

I am aware that agonists of the $\alpha_7 $ nAChRs improve cognition in Schizophrenia, presumably by catalysing the release of histamine, norepinephrine and/or acetylcholine.1,2 I also know that $\alpha_7 $ nAChRs antagonists reduce $\Delta^9$-tetrahydrocannabinol (THC) self-administration in mice presumably by suppressing dopaminergic activity in the nucleus accumbens or by inhibiting the activity of the CB1 receptor.3 Selective CB1 antagonists also manage to reduce nicotine dependence.4 Also I know that the activation of the $ \alpha_3 \beta_4 $ nAChRs in the adrenal medulla catalyses an epinephrine and norepinephrine release.
