The tempo of the CD103+ and CD11bhi DC accumulation, i.e. onset between 1 and 2 days p.i., paralleled the previously reported tempo of activation of naïve CD8+ T cell activation in the MLN following sub-lethal influenza infection [7], [8] suggesting a potential role for these accumulating CD103+ and CD11bhi DC in T cell activation in the MLN. The gene discussed is CD8A; the disease is influenza.
