ABSTRACT
【Objective】 To determine the effect of storage time on the chemokine storage and chemokine scavenging function of erythrocyte atypical chemokine receptor 1(ACKR1). 【Methods】 Samples from six bags of red blood cells product, split into two gruoups(10 mL each), were stored in a refrigerator and sampled on day 5 and day 25 during storage, respectively, to measure the concentrations of CCL5, CXCL8 and CCL11 and the ACKR1 chemokine scavenging function of erythrocytes. In addition, 42 erythrocyte products(1 mL each), stored for 5 to 25 days, were sampled to measure the expression of ACKR1 and the concentrations of chemokines CCL5, CXCL8 and CCL11 on the erythrocyte membrane. 【Results】 Compared with RBCs stored for 5 days, no difference in the concentration of CCL5(467.7±250.2 pg/mL vs 586.9±209.5pg/mL, P>0.05) and CCL11(122.2±30.3pg/mL vs 125.5 ±32.7pg/mL, P>0.05)were noticed in erythrocyte lysates stored for 25 days, but the concentrations of CXCL8 decreased significantly(42.4±5.3pg/mL vs 24.3± 5.9pg/mL, P0.05). 【Conclusion】 Erythrocytes are the main places for storing ACKR1 binding chemokines. During the storage, the chemokine scavenging of erythrocyte ACKR1 and some intracellular the ACKR1 binding chemokines are reduced.
