In contrast, neither the transcripts of CCR1 or CCR2 nor their proteins were detected in the EBV-negative and EBV-carrying BL cell lines with latency I. Enhanced transcription of CCR2, CCR7, and CCR9 was previously detected in tonsillar B cells upon EBV infection in vitro [4]. The gene discussed is CCR2; the disease is Epstein-Barr virus infection.
