LMP1+SLAMF1high cells are associated with drug resistance in Epstein-Barr virus-positive Farage cells

We isolated Farage cells expressing the cell surface marker SLAMF1. LMP1 and its target gene CCL22 were highly expressed in SLAMF1high Farage cells. These cells survived longer following treatment with a combination of cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP). Genes associated with interferon-alpha, allograft rejection, NF-kB, STAT3 and 5 were also overexpressed in the surviving Farage cells.
