Anti–IFN-γ reverses SEA-induced anergy. Treatment with anti–IFN-γ Ab increased CD4+ T cell recovery and viability after SEA treatment. (a) CD4+ T cells from SEA-treated and control AND mice were cultured with neutralizing concentration of anti–IFN-γ Ab (XMG1.2). Live cell recovery on day 4 is shown. Cells recovered from above cultures were analyzed for live cell content. (b) Percentage of live cells as determined by F/S. (c) Percentage of CD4+ cells that stained positively with PI. Gated populations of CD4+ cells are shown.
