In view of the above findings implicating the lung as the site of origin of the CD103+ and CD11bhi DC subsets accumulating in the draining MLN of influenza-infected mice (as well as at least some of the Gr-1+ MoDC in the MLN), it was of interest to examine the kinetics of accumulation of these distinct DC subsets in the MLN, as a basis for establishing if one or more of these DC subsets may play a critical role in antigen delivery and/or presentation to adaptive immune cells responding in the MLN (see below). Here, ITGAE is linked to influenza.
