CCR2 and myeloproliferative disorder: To examine if γδ+ and αβ+ T-cells have corresponding receptors (CCR2 and CCR3) for the cytokines (MCP-1 and eotaxin, respectively) which were increased in both CML groups, samples from IFN-ON (n = 4), IFN-OFF (n = 3), MPN control patients (n = 3), and healthy volunteers (n = 5) were analyzed with flow cytometry.
