Expression Of The Chemokine Receptor, Cxcr4, And Its Ligand, Sdf-1, Are Increased In Purkinje Cells Of The Multiple System Atrophy Cerebellum, Megan Welter
Masters Theses
Multiple System Atrophy (MSA) is a sporadic, neurodegenerative disease that consists of three conditions: autonomic dysfunction, Parkinsonism and cerebellar ataxia. Our lab conducted an Affymetrix global gene expression analysis using pons tissue of MSA patients to determine genes that are differentially expressed when compared to non- MSA controls. This study identified upregulated genes, including the C-X-C chemokine receptor type 4, CXCR4, to which stromal cell-derived factor-I (SDF-1) is the natural ligand. The CXCR4/SDF-1 signaling pair has been sho.wn to play multiple roles in the brain, such as inducing neuronal apoptosis and promoting leukocyte recruitment during inflammation. The MSA cerebellum presents …
