Pr4△35 exhibits a growth defect in vivo and is attenuated in
pigs (54) (Zsak et al., unpublished). The inability of Pr4△35 to
suppress an IFN response may be a significant factor in the
attenuated phenotype. Pr4△35 infection induces expression of
two known chemokines: MCP-1, a C-C-type chemokine that
attracts monocytes and promotes mast cell activation, and IP-
10, a CXC chemokine that attracts monocytes, T lymphocytes,
and NK cells and has the capacity to control viral replication
(15, 30, 35). Other Pr4△35-induced genes with a potential
impact on viral virulence and host range are the Mx protein
and IFN-induced TM-3. Mx proteins are IFN-regulated GTPbinding
proteins of the dynamin family that block influenza
virus mRNA synthesis in the nucleus (3, 24). TM-3 is a protein
highly inducible by IFN-α, -β, and -γ (11). Pr4△35 infection
induces expression of the proteolysis-related genes ISG15 and
ISG43. ISG15 induct
