Increased thalamic neurodegeneration following ischaemic cortical stroke in osteopontin-deficient mice.
Inflammation aggravates brain injury caused by stroke and neurodegeneration. Osteopontin (OPN) is a cytokine-like glycoprotein that binds to various integrins and CD44 variants. OPN exerts proinflammatory effects in autoimmune conditions but also has cytoprotective properties and participates in wound healing. In this study, we addressed the role of OPN in ischaemic brain injury using OPN knock...
متن کاملAltered bleomycin-induced lung fibrosis in osteopontin-deficient mice.
Osteopontin is a multifunctional matricellular protein abundantly expressed during inflammation and repair. Osteopontin deficiency is associated with abnormal wound repair characterized by aberrant collagen fibrillogenesis in the heart and skin. Recent gene microarray studies found that osteopontin is abundantly expressed in both human and mouse lung fibrosis. Macrophages and T cells are known ...
متن کاملOsteopontin deficiency attenuates atherosclerosis in female apolipoprotein E-deficient mice.
OBJECTIVE Osteopontin (OPN), a noncollagenous adhesive protein, is implicated in atherosclerosis, in which macrophages within atherosclerotic plaques express OPN. However, it is not known whether the elevated OPN expression is a cause or result of atherosclerosis. METHODS AND RESULTS We generated mice that lacked OPN and crossed them with apolipoprotein (apo) E-deficient mice and analyzed the...
متن کاملProgressive spinal axonal degeneration and slowness in ALS2-deficient mice.
OBJECTIVE Homozygous mutation in the ALS2 gene and the resulting loss of the guanine exchange factor activity of the ALS2 protein is causative for autosomal recessive early-onset motor neuron disease that is thought to predominantly affect upper motor neurons. The goal of this study was to elucidate how the motor system is affected by the deletion of ALS2. METHODS ALS2-deficient mice were gen...
متن کاملParkinson Phenotype in Aged PINK1-Deficient Mice Is Accompanied by Progressive Mitochondrial Dysfunction in Absence of Neurodegeneration
BACKGROUND Parkinson's disease (PD) is an adult-onset movement disorder of largely unknown etiology. We have previously shown that loss-of-function mutations of the mitochondrial protein kinase PINK1 (PTEN induced putative kinase 1) cause the recessive PARK6 variant of PD. METHODOLOGY/PRINCIPAL FINDINGS Now we generated a PINK1 deficient mouse and observed several novel phenotypes: A progress...
