Lithium, a drug used to treat bipolar disorders, has a variety of neuroprotective
mechanisms, including autophagy regulation, in various neuropsychiatric
conditions. In neurodegenerative diseases, lithium enhances degradation of
aggregate-prone proteins, including mutated huntingtin, phosphorylated tau, and
?-synuclein, and causes damaged mitochondria to degrade, while in a mouse model
of cerebral ischemia and Alzheimer's disease autophagy downregulation by lithium
is observed. The signaling pathway of lithium as an autophagy enhancer might be
associated with the mammalian target of rapamycin (mTOR)-independent pathway,
which is involved in myo-inositol-1,4,5-trisphosphate (IP3) in Huntington's
disease and Parkinson's disease. However, the mTOR-dependent pathway might be
involved in inhibiting glycogen synthase kinase-3? (GSK3?) in other diseases.
Lithium's autophagy-enhancing property may contribute to the therapeutic benefit
of patients with neuropsychiatric disorders.
