Figure 1From: Characterization and function of the human macrophage dopaminergic system: implications for CNS disease and drug abuse Human macrophages express mRNA for all dopamine receptors (DRs). Quantitative RT-PCR (1A) detected mRNA for D1R, D2R, D3R, D4R and D5R in monocyte derived macrophages (MMD) isolated from 4 different donors. Representative amplification curves from a single donor are shown for each DR (red curves) and the housekeeping gene β-actin (red curves). Amplification curves for the positive control (Total Human brain RNA, blue curves) and the negative control (cDNA negative samples, green curves) are also shown.Back to article page
