Quantities of specific interactions between agents representing leukocytes in Zone 2. The median (squares), 25th percentile and 75th percentile of number of links per node for the indicated combinations of agents and time points for the win (n = 100, open squares) and the loss (n = 46, filled squares) outcomes are shown. The first agent type listed indicates which agent recorded the contact. An asterisk between the win and loss results indicate significant differences at the recorded time point (*p-value < = 0.0016) using a two-tailed Mann-Whitney U-test with the Bonferroni correction for multiple comparisons. The abbreviations are as follows: B, BCell Agent; CTL, CTL Agent; DC, Dendritic Agent; T, TCell Agent.
