| Popis: | Objective To investigate the effect of phenotypes of Duffy blood group on chemokine storage and chemokine scavenging function of erythrocytes. Methods Twenty-four erythrocyte samples were collected and tested Duffy blood phenotype using the anti-human globulin method, and erythrocyte CCL2, CCL5, CXCL8, and CCL11 content and their chemokine scavenging function using ELISA. The expression of Duffy antigens on erythrocytes was detected using a flow analyzer. Results The difference in CCL2 content(41.1±14.7 pg/mL vs 63.1±20.8 pg/mL)of erythrocyte lysate between Fy(a+b-) and Fy(a+b+) phenotype was statistically significant (P0.05).The difference in the scavenging function of CCL2(1471±202.1 pg/mL vs 1860±267.5 pg/mL)and CCL5 (848.5±461.7 pg/mL vs 1797±546.1pg/mL) between Fy(a+b-) and Fy(a+b+) phenotype were statistically significant (P0.05).The difference in Duffy antigen expression (mean fluorescent intensity:105.3±20.45 vs 111.9±18.30)on erythrocytes between Fy(a+b-) and Fy(a+b+) phenotype was not statistically significant (P>0.05). Conclusion The Fy(a+b+) and Fy(a+b-) phenotypes of the Duffy blood group can affect the chemokine storage and scavenging function of erythrocytes. Fy(a+b+) phenotypes are able to store more chemokines and have a stronger chemokine scavenging function than Fy(a+b-) phenotypes. |
