title: [Signal transduction and biological characteristics of EB virus-encoded latent membrane protein 1 and its correlation with CD40].
abstract: The oncogenic Epstein-Barr virus (EBV) -encoded latent membrane protein 1 (LMP1) enables this virus's long-term survival within the cells of immune system. Mean while, LMP1 also plays a critical role for the transformation of resting B cells by EBV. It initiates the activation of signalling pathways, such as NF-kappaB, mitogen-activated protein kinase (MAPK), and JAK/STAT cascade by adaptor proteins including the tumor necrosis factor (TNF) receptor associated factors (TRAFs) and the TNF receptor associated death domain protein (TRADD). It increases the expression of adhesion molecules LFA-1, ICAM-1, and costimulatory molecule B7-1 of B cells, and regulates the antibody and cytokine secreted by B cells. LMP1 and CD40 have many common properties in signal transduction. Both of them co-localize in lipid rafts for signal transduction. Considering its close relationship with CD40, the research on LMP1 has become a hot spot in the immunology field.
