Murine L5178Y-R lymphoma cells (ATCC CRL-1722) and PBMC were used in this study. PBMC were obtained from a 50 mL to 60 mL blood sample from a healthy donor, using Ficoll-Paque PLUS (GE Healthcare Life Sciences, Pittsburgh, PA, USA) and following supplier’s instructions. L5178Y-R cells and PBMC were maintained in RPMI 1640 culture medium (Life Technologies, Grand Island, NY, USA), supplemented with 10% heat-inactivated fetal bovine serum (FBS; Life Technologies) and 1% antibiotic/antifungal solution (Life Technologies) (referred as complete 1640 medium) at 37 °C in an atmosphere of 5% CO2 in air [17 (link)].
