Soluble BLyS is released from myeloid cells.
The amount of released BLyS was determined by ELISA in the medium, which was conditioned for 3 days, from the following cell cultures: (A) U937, HL-60, Namalwa, IM-9, and Jurkat (plated at the cell density of 1 × 106 cells per mL) and (B) 3 × 106 cells per mL B cells and monocytes and 1 × 106 cells per mL macrophages and dendritic cells.
