Comparison of the killing activity of CD4, CD8, and γδ T cells. A Representative set of results illustrated with the CT values obtained with unseparated cell populations. The CT values represent the average of duplicate preparations of DNA run at the same time. B A two-way ANOVA for the effect of mdPBMC stimulation (two levels: control, MMP), reponses grouped by unvaccinated steers (n = 4). The mean and standard deviation for each stimulation level (control, MMP) of mdPBMC from four unvaccinated steers. The effect of MMP stimulation was significant (F
= 130.4208; P = 0.0014). C No statistics were applied since only two of the four unvaccinated steers were used to obtain data on separated cell subsets.
