Mutual regulation of EBV LMP1 and CD99 in the pathogenesis of EBV‐associated Hodgkin lymphomas

This is the authors' abstract. We don't add key points for this paper.

Despite considerable progress over the last decade, Hodgkin lymphoma (HL) remains a malignant tumor of unknown pathogenesis. The role of Epstein‐Barr virus (EBV) and the activation of transcription factor NF‐κB have been noted in the tumorigenesis of classic HL. Recently, a distinctive interaction between CD99 and the EBV viral latent membrane protein 1 (LMP1) was observed in the process of the malignant transformation of EBV‐infected B cells. It was previously reported that CD99 expression is negatively regulated by LMP1, subsequently generating cells with Hodgkin and Reed‐Sternberg (HRS) cell phenotype. Interestingly, several pieces of evidence have been recently revealed the presence of mutual regulation between CD99 and LMP1, which may assist in determining HL pathogenesis. In this review, the roles of CD99 and LMP1 in the generation of the HRS cell, a tumor cell of HL, will be discussed. We also suggest that CD99 and LMP1 interaction in an in vivo system may provide new insight into the understanding of the molecular mechanism of HL.
