Identify genes differential expression and pathways in CD19~+ B cells of multiple sclerosis with optic neuritis patients

Objective to analyze the characteristics of gene markers in peripheral blood CD19+B cells of multiple sclerosis patients with optic neuritis by bioinformatics.Methods Gene chip expression profiles of peripheral blood CD19+B cells of multiple sclerosis patients with optic neuritis were obtained from GEO database.Differential expression analysis was performed by GEO2R software online.Functional annotation and pathway analysis of differential genes were performed by GO and KEGG,and protein interaction analysis was performed by string-db database.Results A total of 561 differentially expressed genes were found.These differentially expressed genes were enriched in different biological processes or subsets of molecular functions,mainly enriched in immune response,inflammatory response,signal transduction regulation and other functions,and mainly regulated cytokine receptor interaction and other pathways.Conclusion The differential expressed genes in multiple sclerosis patients with optic neuritis are mainly enriched in the immune response and mediate cytokine receptor interaction pathway.
