Quantification of CCR5 mRNA in human lymphocytes and macrophages by real-time reverse transcriptase PCR assay.

ABSTRACT: CCR5, a beta-chemokine receptor, plays an important role in human immunodeficiency virus (HIV) infection of human immune cells, as it is a primary coreceptor for HIV entry into macrophages. We have applied a newly developed real-time reverse transcriptase PCR (RT-PCR) assay for the quantification of CCR5 mRNA in human blood immune cells. The CCR5 real-time RT-PCR assay has a sensitivity of 100 mRNA copies, with a dynamic range of detection between 10(2) and 10(6) copies of the CCR5 mRNA transcripts per reaction. The assay is highly reproducible, with an intra-assay coefficient of variation of the threshold cycle of less than 2.07%. When used for quantification of CCR5 mRNA in human monocyte-derived macrophages (MDM) and peripheral blood lymphocytes (PBL), the assay has precision and reprod
