abstract：:In this study, we show that IFNalpha increases the chemotaxis of human B cells to CCL20, CCL21 and CXCL12 in a dose- and time-dependent manner. The effect was maximal with 2000 IU ml(-1) IFNalpha. It peaked at 24 h and decreased thereafter. At 24 h, IFNalpha had increased B-cell chemotaxis to CCL20 by 20 +/- 6.2% (n =...
