IAV H1N1 and H9N2 subtypes induced autophagy in A549 cells and HPMECs.

Cells were infected with IAV subtypes H1N1 or H9N2 at an MOI of 1. Anti-LC3 antibody was used to stain the cells for immunofluorescence microscopy at 24 hrs post infection. (A) A549 cells; (B) HPMECs. Scale bar, 10μm; (C) Quantitative analyses of autophagosomes in infected and non-infected A549 and HPMECs (** p<0.05; ***p<0.01).
