Expression patterns of the genes classified into 5 functional groups in GC-Th cells versus other memory/effector T-cell subsets. (A) Migration-related genes. (B) Cell-cycle– and apoptosis-related genes. (C) Chemokine- and cytokine-related genes. (D) Cytokine receptors. (E) Transcription-related genes. Each clustered image accompanies a dendrogram showing the relationship (in r values from Pearson correlation) among the T-cell subsets or 12 experiments (3 per subset) in gene expression. Genbank accession numbers are shown along with gene names.
