Figure 1.

Gene networks in long-lived CD4 memory T cells. Five different gene programs were identified as dynamically regulated during memory CD4 T cell differentiation. The genes shown were from the long-lived memory CD4 cells 10.5 months post immunization as compared to naïve controls and are marked in different colors: Yellow: cell proliferation; Green: DNA repair; Red: Apoptosis; Light blue: Lipid metabolism; Dark blue: Carbohydrate metabolism; Black: Not identified in the five gene programs but served as connecting genes. Each line represents an interaction/co-expression of genes as identified by literature report.
