Project description:The aim of this study was to identify differentially expressed genes in peripheral blood mononuclear cells from MS patients that were responders or non-responders to the neuroantigen myelin basic protein. Using microarray we measured mRNA-expression levels in freshly isolated peripheral blood mononuclear cells from 17 untreated patients with multiple sclerosis. Based on studies, measuring the responses of blood derived T-cells to myelin basic protein ex vivo, these 17 untreated MS-patients can be divided into two groups: 4 of the untreated multiple sclerosis patients had T-cells that responded to myelin basic protein ex vivo whereas 13 untreated MS patients had T-cells that did not respond to myelin basic protein ex vivo.
Project description:Background: pregnancy is associated with reduced activity of multiple sclerosis (MS). However, the biological mechanisms underlying this pregnancy-related decrease in disease activity are poorly understood. This data series contains the subset of data used to generate a MS signature comparing female MS specimens before pregnancy with respect to female MS specimens at ninth month pregnancy.
