Pathways depicted within the figure are three notable sites benefit of an inhibitory combat of lithium: inositol 1-monophospha- tase (IMPase); inositol polyphosphate 1-phosphatase (IPPase); and glycogen synthase kinase 3 (GSK-3 ). Curb of IMPase and IPPase can come to pass in a reduction of myo-inositol (myo-Ins)and subsequent changes in the kinetics of receptor-activated phospholipase C (PLC)breakdown of phosphoinositide-4,5-bisphosphatetodiacylglycerol(DAG)andinositol-1,4,5-trisphosphate. Alter- ation in the cataloguing of inositol phosphates can upset mechanisms mediating presynaptic present. DAG presently activates protein kinase C (PKC), and this activation results in downstream post-translational changes in proteins that stir receptor complexes and ion aqueduct vim and in transcription factors that alter gene symbol of proteins such as MARCKS (myristoylated alanine-rich C-kinase substrate), which are elemental to long-term neuroplastic changes in cubicle func- tion. Blockage of GSK-3 within the wnt-receptor (wnt-R)pathway alters gene transcription and neuroplastic events auspices of an increased intonation of downstream proteins such as -catenin.
