A Gene Expression Signature That Correlates with CD8+ T Cell Expansion in Acute EBV Infection.

ABSTRACT: Virus-specific CD8(+) T cells expand dramatically during acute EBV infection, and their persistence is important for lifelong control of EBV-related disease. To better define the generation and maintenance of these effective CD8(+) T cell responses, we used microarrays to characterize gene expression in total and EBV-specific CD8(+) T cells isolated from the peripheral blood of 10 individuals followed from acute infectious mononucleosis (AIM) into convalescence (CONV). In total CD8(+) T cells, differential expression of genes in AIM and CONV was most pronounced among those encoding proteins important in T cell activation/differentiation, cell division/metabolism, chemokines/cytokines and receptors, signaling and transcription factors (TF), immune effector functions, and negative regulators
