abstractText | We report here that amyotrophic lateral sclerosis-linked superoxide dismutase 1 (SOD1) mutants with different biochemical characteristics disrupted the blood-spinal cord barrier in mice by reducing the levels of the tight junction proteins ZO-1, occludin and claudin-5 between endothelial cells. This resulted in microhemorrhages with release of neurotoxic hemoglobin-derived products, reductions in microcirculation and hypoperfusion. SOD1 mutant-mediated endothelial damage accumulated before motor neuron degeneration and the neurovascular inflammatory response occurred, indicating that it was a central contributor to disease initiation. |
