Figure 6. Expression of HLA-DR and costimulatory molecules on dendritic cells during their maturation. iDC – immature dendritic cells; LPS, TNFα+PGE2 – mature dendritic cells stimulated to mature by the corresponding method; gray peak – unstained control (immature dendritic cells). The x-axis represents fluorescence intensity; the y-axis represents the normalized number of recorded events (cells).
