The genes Cxcr5, Inhbb, and Tnfrsf11b were exceptions, as significant changes in the three genes were not demonstrated in the microarray data, although significantly decreased (Cxcr5) and increased (Inhbb, and Tnfrsf11b) levels were observed in the DSS and AOM/DSS groups, respectively. The gene discussed is CXCR5; the disease is infectious otitis media.
