Removal of TNFα from DC cultures results in reduced levels of CD80, CD86, and CD83 expression. TNFα added to 7-day DC cultures was subsequently removed by washing the cells 2 and 4 days later [denoted as TNF day 2(−) and TNF day 4(−), respectively]. The cultures were then replated in fresh SFM with added GM-CSF and IL-4 for an additional 5 or 3 days, respectively. Comparisons were made with DC cultured without TNFα (denoted Non-TNF DC) and those cultured in TNF for the complete 7-day period [denoted TNF day 7(+)]. FACS analysis of mean fluorescence channel is depicted. The results are representative of two experiments.
