MOESM2 of Canine respiratory coronavirus employs caveolin-1-mediated pathway for internalization to HRT-18G cells

Additional file 2. Chemical inhibitors effect on CRCoV infection. Graphs shows number of virus positive cells at 5th day pi normalized to control. HRT-18G cells were treated with acidification (A), dynamin (B), cell kinases (C), cytoskeleton (D), clathrin (E), macropinocytosis (F) and caveolin (G) inhibitors. Compounds were present prior and during the infection (white) or only after infection (gray). Cells were propagated in their presence until harvested.
