Meantime, JAWS II cells infected with ECTV showed significantly (p ≤ 0.05) reduced MFI value for green fluorescence at 12 hpi (Fig. 6a), despite the unchanged expression of Ctsb, Ctsl and Ctss mRNA and protein expression for cathepsins B and L at this time post infection (Figs. 2, 3). The gene discussed is CTSB; the disease is infection.
