Viremia is commonly observed in association with enterovirus infections,
and during this phase viruses can be transmitted to secondary target organs
in the body. It is not known, however, whether blood cells play a role in
the pathogenesis of enterovirus infection supporting virus replication. Our
earlier work (T. Vuorinen, R. Vainionpaa, H. Kettinen, and T. Hyypia, Blood
84:823-829, 1994) demonstrated that coxsackievirus B3 is able to replicate
in representatives of B- and T-cell lines but not in a monocytic cell line
or peripheral blood mononuclear cells, indicating that virus replication
may depend on the differentiation and maturation stages of the cells.
Therefore, we have broaden our studies and analyzed the susceptibility of
granulocyte-macrophage CFU and hematopoietic cell lines with various
differentiation and maturation stages to coxsackievirus B3 infection. Virus
replication was detected in B- and T- cell lines with no direct correlation
to the maturation stage. Granulocyte-macrophage CFU were also able to
support virus multiplication.
