2000b; Sassi et al. Lithium-induced attenuation of presynaptic DA function can affect the phosphorylation and activity of GSK3 [McQuade and Robinson, 2012], and further contribute to its inhibition by lithium treatment. HHS This resuts in polyuria and polydisia. Animal studies will be vital, however, for comparative analyses to determine which of these defense mechanisms are most required to slow-down cognitive decline in dementia, and whether combination therapies can synergize systems to exploit lithium’s neuro-protective power while avoiding deleterious toxicity.

Lithium competes with magnesium in several enzymatic reactions at substrate sites that require magnesium as a co-factor. The Hub gives you an opportunity to make a difference. Aripiprazole alone or in combination for acute mania. Lithium limits the ability of the kidney to store free water by reducing the cAMP response to anti-diuretic hormone. Neurobiol.

Lithium and the Interplay Between Telomeres and Mitochondria in Bipolar Disorder. Conversely, both lithium and specific GSK-3 inhibitors prevented neuro-inflammatory IL-1β, IL-6, TNFα and nitric oxide (NO) production in rat microglia (Yuskaitis and Jope, 2009; Green and Nolan, 2012) and astrocytes (Wang et al., 2013), as well as in mouse hippocampal slice cultures in correlation with neuronal protection (Yuskaitis and Jope, 2009). doi: 10.1016/j.jalz.2016.02.010, Campolo, M., Casili, G., Lanza, M., Filippone, A., Paterniti, I., Cuzzocrea, S., et al. Accumulating pre-clinical evidence has indeed provided a basis for research into the therapeutic use of lithium for the treatment of dementia, an area of medical priority due to its increasing global impact and lack of disease-modifying drugs. 2004; Gould et al. doi: 10.1016/j.ymgme.2004.02.002, Beurel, E., and Jope, R.

Dopaminergic and serotonergic (dys)functioning in mental illness has been heavily researched, although much of this research has focused on the neurotransmitter–receptor complexes, not least because these are the sites for antipsychotic and antidepressant medication functioning, and less on the more complex downstream effects. TOR-mediated cell-cycle activation causes neurodegeneration in a Drosophila tauopathy model. doi: 10.1016/j.jalz.2014.04.006, Wang, H.-M., Zhang, T., Li, Q., Huang, J.-K., Chen, R.-F., and Sun, X.-J. J. Cereb. Neuropsychopharmacology. GSK3 inhibition is therefore an attractive hypothesis, providing a further explanation for lithium’s pharmacodynamic actions. 24, 6791–6798. Acad. 45, 425–437. 584, 1287–1295. The promise of lithium as a multi-functional therapy for the treatment of dementia therefore remains. 37, 217–226. Contrasting studies in mice, however, suggest that inositol depletion may not alter PIP levels in the CNS (Berry et al., 2004).

Furthermore, IMPA1 deletion only partially mimics lithium’s effects on gene expression in the hippocampus (Damri et al., 2015) and IMPA2 deletion fails to phenocopy lithium’s protective effects against depression and anxiety-like behavior (Cryns et al., 2007). 2009]. Lithium and autophagy. Additionally, the researchers hypothesize, lithium acts to block the serotonin “transporter” protein. Curr. J. Cereb. 2000a]. doi: 10.1016/j.brainresbull.2015.02.008, Lucas, J.

Pharmacologic treatments for pediatric bipolar disorder: A review and meta-analysis. The benefits of this may include improved neuronal function by re-investing energy in cell maintenance processes, or delaying formation of protein aggregates by improving protein quality due to the increased availability of the protein folding and degradation machinery. Inhibition of glycogen synthase kinase 3 (GSK3) by lithium. The molecular mediators of lithium’s anti-inflammatory effects in dementia models are unclear, but correlative evidence suggest that GSK-3, toll-like receptor 4 (TLR4), signal transducer and activator of transcription (STAT) and nuclear factor-κB (NFκB) pathways may play a causal role (Jope et al., 2017; see Figure 1B). (2011). Glycogen synthase kinase-3 haploinsufficiency mimics the behavioral and molecular effects of lithium. Chronic lithium treatment elicits its antimanic effects via BDNF-TrkB dependent synaptic downscaling. width: "100%", doi: 10.1038/nrd.2017.22, Gelfo, F., Cutuli, D., Nobili, A., De Bartolo, P., D’Amelio, M., Petrosini, L., et al. In the early 20th century, beverages such as Lithia beer and 7-Up contained trace amounts of Lithium. If you have the appropriate software installed, you can download article citation data to the citation manager of your choice. FEBS Lett. Low dose lithium also delayed disease in ALS patients (Fornai et al., 2008a), and neuroprotection by lithium in the SOD1G93A mouse model of ALS has been attributed to increased autophagy (Fornai et al., 2008a,b). doi: 10.1073/pnas.0403678101, Jope, R. S., Cheng, Y., Lowell, J. For example by altering DNA replication, metabolism and endoplasmic reticulum (ER) genes in worms (McColl et al., 2008), translation and cellular detoxification genes in flies (Castillo-Quan et al., 2016), and neurogenesis, synaptic function, anti-apoptosis and anti-inflammatory genes in rat and mouse brain (Roux and Dosseto, 2017). Understanding the Mechanism of Action of Lithium and the Pathophysiology of Bipolar Disorder with Molecular Imaging of the Serotonin System. (2017). Similarly in Drosophila fmr1 (dfmr1) mutant flies, lithium significantly improved mushroom body defects and restored learning and memory capabilities, as measured by altered courtship behavior, through a reduction in mGluR activity (McBride et al., 2005). The mitochondria are the energy powerhouses i.e. Rapamycin attenuates the progression of tau pathology in P301S Tau transgenic mice. (2007). The mechanism by which lithium exerts its effects on the PI signalling pathway is still unclear, and it remains possible, for example, that a decrease in intracellular myo-inositol is only the first stage of action, initiating a cascade of secondary changes in the PKC signalling pathway and gene expression [Agam et al. Significance of NF-κB as a pivotal therapeutic target in the neurodegenerative pathologies of Alzheimer’s disease and multiple sclerosis. Acute administration of lithium increases basal levels of AC and cAMP by inhibiting the G inhibitory protein. The Hub is a device to unlock this knowledge and share it with the wider world.

Alterations in such neuro-inflammatory factors have indeed been shown to correlate with cognitive improvement by lithium using these mammalian models. Sci. Further research is now needed, to clarify the clinical relevance of these findings and determine the mood stabilising effects of GSK3 and IMPase inhibition in patients with mood disorders [Beaulieu et al.
