Inhibitors of cytochrome P450 suppress tumor necrosis factor production.

abstract：:Cluster of differentiation ([CD]) 19 antigens are B-cell-specific molecules expressed on virtually all human cells of the B-lymphocyte lineage except plasma cells. We produced a new anti-CD19 monoclonal antibody (McAb), CLB-CD19, that was used to study the role of CD19 molecules in B-cell activation. Anti-CD19 McAb in...
