Figure 2From: A trypsin-like serine protease is involved in pseudorabies virus invasion through the basement membrane barrier of porcine nasal respiratory mucosaPlaque latitude and penetration depth underneath the basement membrane (BM) of PRV(89V87) plaques at 20 h pi in mock-treated (white bars) and protease inhibitor-treated (marked bars) porcine nasal respiratory mucosa explants. Explants were treated with 100 or 250 μM AEBSF, 1 or 10 μM E-64 or 10 μM phosphoramidon at 1 h pi until sampling. Data are represented as means of 10 plaques of triplicate independent experiments + SD (error bars).Back to article page
