Expression of matrix metalloproteinases and tissue inhibitors of metalloproteinases in the hippocampus of lithium-pilocarpine-induced acute epileptic rats.

Wan D, Yang L, Ren J, Huang H, Zhang C, Chen L, Su X, Huang Q, Niu J, Sun T, Wang P.Mol Biol Rep. 2022 Jul;49(7):5805-5810. doi: 10.1007/s11033-022-07277-5. Epub 2022 Jun 17.PMID: 35715602

Background: Epilepsy is characterised by abnormal neuronal discharges, including aberrant expression of extracellular matrix (ECM) components and synaptic plasticity stabilisation. Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) interact to remodel the ECM in the central nervous system (CNS), to modulate synaptic plasticity in epileptogenesis.

Methods and results: In the present study, the expression of MMP activators (tPA and uPA), 10 MMPs, and 3 TIMPs was detected by western blot analysis and quantitative polymerase chain reaction (RT-qPCR) to assess their potential pathogenetic role in the epileptogenesis in the hippocampus of lithium-pilocarpine hydrochloride-induced epileptic rats. Our results showed that The expression of MMP7 and MMP14 was impeded in the hippocampus of lithium-pilocarpine-induced acute epileptic rats compared with that in controls. The transcriptional level of tPA was enhanced on day 1 post-seizure in the hippocampus, while the levels of several MMPs and TIMPs did not change on days 1 and 3 post-seizure compared with that in controls.

Conclusions: The expression of MMPs and TIMPs reflects a novel feature of epileptogenesis and may offer new perspectives for future therapeutic interventions.

[Parkinsonian dystonia].

Dowsey-Limousin P.Rev Neurol (Paris). 2003 Oct;159(10 Pt 1):928-31.PMID: 14615683 Review. French.

There are several medical options to try and improve those dystonias, adjustment of levodopa doses, adding a dopamine agonist drug, anticholinergics, lithium, baclofene or clonazepam. Those options are not always very effective. Botulinum toxin injections are an alternativ …

Lithium protects dopaminergic cells from rotenone toxicity via autophagy enhancement.

Hou L, Xiong N, Liu L, Huang J, Han C, Zhang G, Li J, Xu X, Lin Z, Wang T.BMC Neurosci. 2015 Nov 25;16:82. doi: 10.1186/s12868-015-0222-y.PMID: 26608648 Free PMC article.

CONCLUSIONS: These findings suggested that lithium exerted neuroprotection against rotenone-induced injuries partially through the autophagy pathway. Pharmacologically induction of autophagy by lithium may represent a novel therapeutic strategy as a disease-modifier …

Lithium enhances post-stroke blood-brain barrier integrity,

activates the MAPK/ERK1/2 pathway and alters immune cell migration in mice.

Haupt M, Zechmeister B, Bosche B, Lieschke S, Zheng X, Zhang L, Venkataramani V, Jin F, Hein K, Weber MS, Hermann DM, Bähr M, Doeppner TR.Neuropharmacology. 2020 Dec 15;181:108357. doi: 10.1016/j.neuropharm.2020.108357. Epub 2020 Oct 13.PMID: 33065166 Free article.

Lithium induces neuroprotection against cerebral ischemia, although the underlying mechanisms remain elusive. . Furthermore, stabilization of the BBB as a consequence of lithium treatment was associated with an inhibition of matrix metalloproteinase-9 activity, independent of calveolin-1 regulation. In line with this, flow cytometry analysis revealed that lithium treatment led to a decreased neutrophil invasion and an increased T cell extravasation from the blood compartment towards the brain parenchyma

Miten litiumalkuaine koostui?

Litiumissa on 3 protonia ja 3 tai 4 neutronia. Jos siinä on Z3, A6 , N3 rakenne(6Li) , se on stabiili ja kaikesta stabiilista litiumista 7,5 %. Jos siinä on rakenne Z3, A7, N4, tätä stabiilia litiumia 7Li on 92,5 %. 7Li/6Li suhde Maassa 12.3 ( kuten meteoriiteistakin on saatu) .

Jos kaavamaisesti ( legona "huoneenlämpötilassa" ajattelee litiumelementejä, siitä löytää yhden alfan (2p, 2n) ja yhden deuteriumin ( 1p, 1n) -tai vastaavsti tritiuminukleuksen( 1p, 2n) Elektroneja kuitenkin siinä on 3, koska varaus on +3. Joten elektronikatoa He, D tai HE Tritium suhteen ei ole.

Mutta miten luonnossa Litium syntyy. Löysin seuraavan selityksen. Se voi tulla 3 alfarakenett tumassaan olevasta hiiletä (6C12) tai 4 alfaydinkokoomusta omaavasta hapesta (8O 16) käsin. spallaatiolla isommasta pienemmäksi.

Spallaation määritelmästä: Wikipediasta. Spallaatio on prosessi, missä raskas atomiydin päästää vapaaksi nukleoneja sen jälkeen kun siihen on osunut jokin korkeaenerginen partikkeli.. Jos protoni törmää niin jokaista protonia kohden vapautuu lukuisia spallaatiopartikkelieta, esim neutroneja. Yhtä törmäävää protonia kohden voi raskaasta ytimestä irtautua 20-30 neutronia. Mutta tässä litiumin suhteen katsotaan vain hieman sitä isompia ytimiä, kuten hiiltä ja happea.

Yksi selitys litiumin synnystä on ohessa.
