DISC1 and major depressive disorder: (2014) The investigated cell cultures comprised more than 90% cells expressing vGLUT1 or alpha Ca++/calmodulin‐dependent protein kinase II (α‐CAMKII) neurons derived from two patients suffering from SCZ and major depression from a pedigree carrying a frame shift mutation in DISC1. α‐CAMKII has been found to be of relevance for the induction of sensitization to amphetamine (Steinkellner et al., 2014).
