Modification of Cɛ mRNA Expression by EBV-Encoded Latent Membrane Protein 1

To evaluate the effect of expression of latent membrane protein (LMP) 1 encoded by Epstein-Barr virus (EBV) on Cepsilon mRNA expression, mRNA levels were examined by RT-PCR or Northern blot analysis upon transient transfection of LMP1 in the splenocytes derived from Brown-Norway rats with or without immunization with 2,4-dinitrophenyl-conjugated Ascaris suum antigen. Splenocytes were transfecte...

Prognostic Significance of EBV Latent Membrane Protein 1 Expression in Lymphomas: Evidence from 15 Studies

BACKGROUND Epstein-Barr virus (EBV) infection has been associated with lymphoma development. EBV latent membrane protein 1 (LMP1) is essential for EBV-mediated transformation and progression of different human cells, including lymphocytes. This meta-analysis investigated LMP1 expression with prognosis of patients with lymphoma. METHODS The electronic databases of PubMed, Embase, and Chinese B...

Direct Immunosuppressive Effects of EBV - Encoded Latent

Latent membrane protein 1, the EBV-encoded oncogenic mimic of CD40, accelerates autoimmunity in B6.Sle1 mice.

EBV infection is associated with development of the autoimmune disease systemic lupus erythematosus (SLE), and EBV can reactivate during SLE flares. Latent membrane protein 1 (LMP1) is an EBV-encoded oncogenic mimic of CD40 that can be re-expressed in PBMCs during SLE flares, as >90% of humans are latently EBV-infected. Whether LMP1 signaling exacerbates SLE is unknown. The phenotype of mice ex...

EBV latent membrane protein-1 protects B cells from apoptosis by inhibition of BAX.

Latent membrane protein 1 (LMP-1) of Epstein-Barr virus (EBV) promotes tumorigenesis by inhibiting apoptosis. We show that an important antiapoptotic activity of LMP-1 is the inhibition of Bcl2-associated protein X (Bax), a potent proapoptotic protein. BAX expression was regulated by LMP-1 activation of nuclear factor kappaB (NF-kappaB) via the C-terminal activation region 1 (CTAR-1) and CTAR-2...
