Figure 5From: Identification of proteases employed by dendritic cells in the processing of protein purified derivative (PPD)DC constitutively express cathepsin D mRNA. Total RNA isolated from the indicated cell types were subjected to RT-PCR analysis for cathepsin D and β-actin. Data are shown, including bone marrow DC and macrophages, as well as 4F7+ splenic DC (splDC), products after 25 cycles of amplification.Back to article page
