NK cells migrate in response to C-C chemokines, including monocyte chemotactic protein-1 (MCP-1) and MCP-3. Increased migration was observed in IL-2-activated NK cells. It was therefore of interest to define the expression in resting and activated NK cells of the MCP-1 receptor (CCR2) for which two cDNAs (A and B) have been described. Specific oligonucleotides and reverse-transcriptase PCR revealed the presence in activated NK cells and mononuclear phagocytes of the fragments expected on the basis of the reported cDNAs. In addition, amplification with a common A/B- and an A-specific oligonucleotide yielded an unexpected, abundant, 1649-bp fragment. Sequence analysis as well as Northern blotting and RNase protection with different probes revealed that the CCR2 gene is expressed in activated NK cells and mononuclear phagocytes as a predominant long transcript (3.4 kb) consisting of CCR2B, followed by a novel sequence (X), corresponding to an intron in the genome, and by a CCR2A-specific portion. The predominant long transcript is polyadenylated and present in the cytoplasm. The augmented migratory capacity of IL-2 activated vs resting NK cells was associated with increased CCR2 transcript levels.
