Species: Human
Experiment Name: Cell culture
Experiment Background: 1. Interestingly, activation of both mature B and T cells by CD40 MoAb and CD3 MoAb, respectively, led to complete downregulation of BLRI.2. Downregulation of BLRl on activated B and T cells. CD19+ tonsillar lymphocytes were isolated by MACS. Cells were cultured on irradiated mouse fibroblasts transfected with the human Fc-receptor in the presence of anti-CD40 MoAb and IL-4.
Experimental Steps: 1. B cells were cultured in Iscove’s medium supplemented with 5 µg/mL bovine insulin, 0.5% bovine serum albumin (BSA), 50 µg/mL human transferin, 5 X 10-5 mol/L β-mercaptoethanol (β-ME) (all from Sigma), and 5% IgG-free FCS (PAA, Linz, Austria). 2. All cultures were performed in the presence of irradiated (8,000 rad) CDw32-transfected Ltk- cells (CDw32 L cells), kindly provided by K. Moore (DNAX, Palo Alto, CA). CDw32 L cells were seeded in 48-well flat-bottom microtiter plates at 2 X 104/well 1 day before MACS-separated CD19+ B cells were added at 5 X 105/well. 3. At the beginning of the experiment, 100 U/mL recombinant human interleukin-4 (rhuIL-4; Genzyme, Cambridge, MA) and 1 pg/mL anti-CD40 MoAb (clone B-B20) were added to give a final volume of 500 uL. 4. Half of the supplemented medium was replaced every other day. BLRl expression of triplicate cultures of B cells was monitored over a 10-day period by flow cytometry. 5. T cells were cultured in RPM1 1640 medium supplemented with 10% FCS and 5 X 10-5 mol/L β-mercaptoethanol (β-ME). 6. For T-cell activation, 24-well plates were coated overnight with anti-CD3 MoAb (clone 26-11-8; 50 ug/mL in carbonate buffer, pH 9.6). 7. After washing extensively with PBS, PBLs were added at 2.5 X 105/well and BLRl expression of CD3+ cells was monitored as described for B cells.
