Bovine herpesvirus type 1 (BHV-1) mutant lacking U(L)49.5 luminal domain residues 30-32 and cytoplasmic tail residues 80-96 induces more rapid onset of virus neutralizing antibody and cellular immune responses in calves than the wild-type strain Cooper.

Abstract excerpt

Bovine herpesvirus type 1 (BHV-1) envelope protein U(L)49.5 inhibits transporter associated with antigen processing (TAP) and down-regulates cell-surface expression of major histocompatibility complex (MHC) class I molecules to promote immune evasion. Earlier, we have constructed a BHV-1U(L)49.5Δ30-32 CT-null virus and determined that in the infected cells, TAP inhibition and MHC-I down regulation properties of...
