Figure 7.
Functional inhibition of CC chemokines by individual and “two-warhead” evasins. (A–C) Neutralization of CCL5 induced THP-1 cell migration by P1243, P1243:G4S:P1156, and P1156:G4S:P1243 respectively. Y-axis shows cell count of THP-1 cells migrating through to the bottom chamber in response to EC80 dose of CCL5. In each case, data from a representative experiment are shown as mean ± s.e.m. of three technical replicates. X-axis shows CKBP concentration (Log10 Molar). IC50 values (M) indicated in each figure were estimated by fitting an agonist response curve with 4 parameters22. (D–F) Summary IC50 data (mean ± s.e.m., and individual data points from three biological replicates) of the indicated CKBPs against CCL5, CCL3 and CCL3L1 respectively. Y-axis shows IC50 (logarithmic scale, M), and x-axis shows each CKBP. CC chemokines were assayed using THP-1 cell migration. Each chemokine was assayed at its EC80 dose. There were no statistically significant differences between the mean IC50 values in each figure.
