TABLE 5.
Percentages of CD4+ CD44high and CD8+ CD44high T cells obtained from the spleens of mock-, VP6/LT(R192G)-, and RRV-immunized neonatal or adult mice that were stimulated to produce cytokines at 10 or 28 dpi, as determined by fluorescence-activated cell sortinga
| Age at immunization | Immunization protocol | Time (dpi) | % of CD4+ CD44high cells with cytokine

Values represent percentages of cells stained in stimulated cultures minus those stained in unstimulated cultures.
Cultures were stimulated with 4 μg of EDIM VP6::6XHis.
Cultures were stimulated with 10 μg of purified RRV particles.
—, values of <0.1%.
