CCL17 and influenza: Transcriptome analysis suggests that different DC subsets acquire different immunological roles during the influenza infection, such as (i) different immunological niches, via expression of specific chemokines by the cDC versus pDC (e.g., CCL17, CCL22); (ii) different temporal timing of activation allowing to mount rapid yet long‐lasting anti‐viral response rather than an untimely exestuation; and (3) differential expression of cell subset‐specific anti‐viral proteins, via the activation of different pathways.
