A) CD4 + T cell activation. B) CD8 + T cell activation. C) NK Cell activation. HD = HIV-negative healthy donor (n = 16). CP = chronic progressor (n = 11). ES = elite suppressor (n = 12). AP = acute progressors (3 recently infected patients with high viral loads). AC1c = time points for which AC1 controlled viremia. AC1v = time points for which AC1 had lost control of viremia. Specific day post initial clinic visit is indicated in legend.
