On the other hand, the CB1R-Cav2.2 binomial is also able to suppress glutamate release in the hippocampus and anterior cingulate cortex through a similar mechanism of action (depolarization-induced suppression of excitation phenomenon) (Borgan et al., 2021), which has been associated with the occurrence of delusions and hallucinations (Egerton and Stone, 2012) and the presence of depression (Moriguchi et al., 2019; Duman et al., 2019). The gene discussed is CNR1; the disease is major depressive disorder.
