Class A scavenger receptor mediates Ag transfer from B cells to macrophages. Macrophages were treated with the following inhibitors for 1 h before being cocultured with BJAB cells pulsed with either nonspecific Ab or anti-Ig (aIgG/M F(ab)2): no inhibitor (untreated (UT)), 2-APB (gap junction protein inhibitor), and anti-SR-A (aSR-A)- or anti-SR-B (aSR-B; CD36)-blocking Abs. Cells were harvested and stained for flow cytometry with Abs for CD19 and CD14. MFI values for transferred Ag (AF488) were determined for the CD19−CD14+ gated populations from three independent experiments (*, p = 0.002).
