The purpose of the present study was to develop a quantitative assay that
could be used to measure the local and systemic immune responses to
specific rotavirus proteins following rotavirus infection of adult mice. To
measure these responses, we used an immunocytochemical staining assay of
Spodoptera frugiperda (Sf-9) cells which were infected with recombinant
baculovirus expressing selected rotavirus proteins. The specificity of the
assay was documented by using a series of monoclonal antibodies to
individual rotavirus proteins. We observed that the assay had high levels
of sensitivity and specificity for a series of VP7- and VP4-specific
neutralizing monoclonal antibodies which recognized conformation-dependent
epitopes on their target proteins. We also studied immunoglobulin G (IgG)
immune responses in serum and IgA immune responses in the stools of mice
infected with wild- type murine rotavirus strain EHPw. In both sera and
stools, the most immunogenic proteins were VP6 and VP4. VP2 was less
immunogenic than VP6 or VP4, and the immune responses to VP7, NSP2, and
NSP4 were very low in serum and undetectable in stools.
