PG - 66-73 LID - 10.1016/j.molimm.2011.12.003 [doi] AB - Dendritic cells (DCs) are professional antigen presenting cells of the immune system that play a crucial role in initiating immune responses and maintaining self tolerance. Better understanding of the molecular basis of DC immunobiology is required to improve DC-based immunotherapies. We previously described the interaction of transcription factor LUMAN (also known as CREB3 or LZIP) with the DC-specific transmembrane protein DC-STAMP in DCs. Target genes of LUMAN and its role in DCs are currently unknown. In this study we set out to identify genes regulated by LUMAN in DCs using microarray analysis. Expression of a constitutively active form of LUMAN in mouse DC cell line D2SC/1 identified Apolipoprotein A4 (ApoA4) as its target gene. Subsequent validation experiments, bioinformatics-based promoter analysis, and silencing studies confirmed that ApoA4 is a true target gene of LUMAN in bone marrow-derived DCs (BMDCs).
