Conversely, expression of CD86 was decreased in Mo-DC infected with ncp BVDV1b TGAN, ncp BVDV2a 28508-5 or ncp BVDV2a 1373 from 100% at 0 hour to 72.64 ± 1.38% (i.e. 28%), 76.31 ± 11.03% (i.e., about 24%) or 71.36 ± 4.08% (i.e., roughly 29%) at 72 hours post-infection, respectively. Here, CD86 is linked to infection.
