Expression of the fMLP receptors is reduced in immature dendritic cells.

Monocyte-derived dendritic cells were FACS sorted to obtain greater than 97% CD1a⁺ cells. mRNA was isolated, and semiquantitative RT-PCR was performed to determine the level of FPR and FPRL-1 mRNA expression by immature dendritic cells relative to primary monocytes. Data represent results of 3 similar, independent experiments.
