↵a Percentage of radioligand binding in the presence of 100 nM CCL2. 100% was determined in the presence of buffer, and therefore values <100% represent displacement.
↵b Percentage of radioligand binding in presence of 1 μM antagonist. 100% was determined in the presence of buffer, and therefore values >100% represent enhancement.
↵* P < 0.05, Student’s t test.
