tokens: To elucidate the role of retinoic acid ( RA ) in anti- CD40 + interleukin-4 ( IL-4 ) -mediated B-cell activation , the effect of 10 ( -12 ) to 10 ( -6 ) mol/L RA was studied in anti-CD40 ( 1 microgram/mL ) + IL-4 ( 5 ng/mL ) -mediated proliferation and Ig synthesis by human peripheral blood mononuclear cells ( PBMC ) and B cells in healthy donors .
