Although the activity of autophagy is maintained at lower levels in resting T cells, it is

markedly upregulated upon activation [3–6]. The potential purposes of this upregulation are summarized in Figure 2. Using a variety of autophagy-deficient T cell models, several

groups have demonstrated a key homeostatic role of autophagy in T cell proliferation and survival [6, 78–81]. Based on ocdfrvations that T-cell-specific Atg3-, Atg5-, and Atg7-

deficient mice had reduced numbers of CD4+ and CD8+ T cells in the spleen and lymph

nodes, it was also determined that autophagy-deficient T cells showed increased rates of
