MCP-1 primes neutrophils for NET formation. (A) Leukocytes of healthy donors (n = 8) were treated with 500 pg/ml of MCP-1 for 2:30 h and analyzed by flow cytometry. Data are presented as percentage of CD66b-positive cells staining for citH3. Groups were compared by Wilcoxon matched-pairs signed rank test. (B) Neutrophils of healthy donors (n = 12) were pre-treated with 125, 250, and 500 pg/ml MCP-1 and then stimulated with 1.3 μM ionomycin (IM) to induce formation of NETs. Data are provided in percent of positive control and are presented as mean ± SD. Experiments were analyzed by repeated measures ANOVA followed by Dunnett’s multiple comparisons test using the group treated with 1.3 μM IM as single comparator. *p < 0.05, ***p < 0.001, ****p < 0.0001.
