Abstract:

Lithium has been used in modern psychiatry for more than 65 years, constituting a cornerstone of long-term treatment for bipolar disorder.A number of biological properties of lithium have been demonstrated, including its antiviral, blood and nervous system protective effects.The effects of lithium on hematopoiesis, mesenchymal, neural stem cells and induced pluripotent stem cells were reviewed. Since the 1970s, lithium's role in maintaining high levels of hematopoietic stem cells (HSCs) and growth factors has been reported. Lithium can improve homing ability, colony forming ability and self-renewal ability of hematopoietic stem cells. Studies on the effects of lithium on neurogenesis have shown that lithium can promote the proliferation of progenitor cells in the hippocampal dentate gyrus and lead to increased mitotic activity of schwann cells. Lithium has been proved to be associated with neuroprotection and neurotrophic effects, and its specific effects are reflected in its improvement of synaptic plasticity, promotion of cell survival and inhibition of apoptosis. In clinical studies, lithium ion therapy has been found to increase the components of gray matter in the brain, especially in the frontal lobe, hippocampus and amygdala. The effects of lithium on stem cells involve multiple mediators and signal pathways, among which the most important mediators and signal pathways are believed to be glycogen synthase kinase-3 (gsk-3) and Wnt/-catenin pathways. In addition, the regulation of cAMP, protein kinase B, phosphatidylinositol 3-kinase (pi3k) and inositol monophosphatase (IMP) levels are also closely related to the effects of lithium. Lithium is currently being used in clinical trials to treat bipolar disorder and reduce the risk of dementia, and has beneficial effects on neurodegenerative diseases. In addition, induced pluripotent stem cells obtained from patients with bipolar disorder have been widely used to study the pathogenesis and the mechanism of action of lithium.
