To analyze the progressive motor deficits during the course of this disease, we investigated fatigability and ability of recovery of spinal motor neurons by testing monosynaptic reflex transmission with increasing stimulus frequencies in the lumbar spinal cord of the SOD1(G93A) mouse model for ALS in a comparison with wild-type (WT) mice. Monosynaptic reflexes in WT and SOD1(G93A) mice without behavioral deficits showed no difference with respect to their resistance to increasing stimulus frequencies. During the progression of motor deficits in SOD1(G93A) mice, the vulnerability of monosynaptic reflexes to higher frequencies-increased, the required time for reflex recovery was extended, and recovery was often incomplete. Fatigability and demand for recovery of spinal motor neurons in SOD1(G93A) mice rose with increasing motor deficits. This supports the assumption that impairment of the energy supply may contribute to the pathogenesis of ALS.

These mice contained labeled projection neurons and labeled microglia/macrophages. In the affected lateral spinal cord (in contrast to non-affected dorsal columns), different phases of microglia-mediated inflammation were observed: highly reactive microglial cells in preclinical stages (in 60-day-old mice the reaction to axonal transection was similar to 180% of control) and morphologically transformed microglia that have lost their function of tissue surveillance and injury-directed response in clinical stages (reaction to axonal transection was lower than 50% of control). Furthermore, unlike CNS microglia, macrophages of the PNS lack any substantial morphological reaction while preclinical degeneration of peripheral motor axons and neuromuscular junctions was observed.

Pathophysiology of the disease is non-cell-autonomous, with toxicity deriving also from glia. In particular, microglia contribute to disease progression. Methylene blue (MB) inhibits the effect of nitric oxide, which mediates microglial responses to injury. In vivo 2P-LSM imaging was performed in ALS-linked transgenic SOD1G93A mice to investigate the effect of MB on microglia-mediated inflammation in the spinal cord. Local superfusion of the lateral spinal cord with MB inhibited the microglial reaction directed at a laser-induced axon transection in control and SOD1G93A mice. In vitro, MB at high concentrations inhibited cytokine and chemokine release from microglia of control and advanced clinical SOD1G93A mice. Systemic MB-treatment of SOD1G93A mice at early preclinical stages significantly delayed disease onset and motor dysfunction. However, an increase of MB dose had no additional effect on disease progression; this was unexpected in view of the local anti-inflammatory effects. Furthermore, in vivo imaging of systemically MB-treated mice also showed no alterations of microglia activity in response to local lesions. Thus although systemic MB treatment had no effect on microgliosis, instead, its use revealed an important influence on motor neuron survival as indicated by an increased number of lumbar anterior horn neurons present at the time of disease onset. Thus, potentially beneficial effects of locally applied MB on inflammatory events contributing to disease progression could not be reproduced in SOD1G93A mice via systemic administration, whereas systemic MB application delayed disease onset via neuroprotection."],["dc.format.extent","13"],["dc.identifier.doi","10.1371/journal.phone.0043963"],["dc.identifier.fs","592827"],["dc.identifier.pmid","22952827"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7861"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60471"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.title","Influence of Methylene Blue on Microglia-Induced Inflammation and Motor Neuron Degeneration in the SOD1G93A Model for ALS"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
