Table II. CXCR1 and CXCR2 internalization in the presence of various stimuli.

IL-8 receptor
IL-8 alone
fMLP alone
IL-8 + fMLP
IL-8 + fMLP + SB203580
%
CXCR1 78.3 ± 1.7 14.9 ± 13.8 82.8 ± 5.7 90.8 ± 1.5
CXCR2 72.0 ± 9.6 12.5 ± 4.8 74.3 ± 1.2 69.6 ± 1.7

Results are shown as the percentage of internalization ± SEM. n = 2 for IL-8 + fMLP and IL-8 + fMLP + SB203580. n = 3 for IL-8 and fMLP.
