Mice were inoculated intranasally with either MV (500 to 1000 PFU) or with medium (uninfected). Splenocytes were prepared 13 days post-infection, stained with indicated antibodies and analyzed by flow cytometry. Results are expressed as the mean percentage (+/−SD) of positive cells (CD69+, CD62L+, CD44high or CD80+) in a given cell subset (CD4+, CD8+ or CD19+) (4 to 6 mice per group). These results are from one experiment representative out of three.
p<0.05.
p<0.01, Student t-test, calculated between CD150 infected and noninfected mice.
