As factors present in serum are known for their potential to induce specific endocytic pathways, we further explored the conditions required for the novel DYNA-IND IAV entry pathway (using the Gluc-entry assay) by inoculating cells in PBS in the presence of increasing concentrations of fetal calf serum (FCS). Growth factor inducible activation of the tyrosine kinase src has also been linked to the induction of macropinocytosis [49] [50] [51] ; consistent with this observation the src inhibitor PP2 [52] specifically inhibited DYNA-IND entry of IAV (Fig. 9A-B) . ./cache/cord-000354-05lnj3w0.txt ./txt/cord-000354-05lnj3w0.txt
