Toll-Like Receptor 7 Stimulates the Expression of Epstein-Barr Virus Latent Membrane Protein 1
Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus. Toll-like receptor 7 (TLR7) is involved in host innate immunity against pathogens, and its aberrant activation is linked to the development of systemic lupus erythematosus (SLE, also called "lupus"). Type I interferons (IFN) are apparently driving forces for lupus pathogenesis. Previously, we found that EBV latent membrane protein 1 (L...
متن کاملLatent membrane protein 1 of Epstein-Barr virus inhibits as well as stimulates gene expression.
The latent membrane protein 1 (LMP-1) of Epstein-Barr virus (EBV) functionally resembles a constitutively active, CD40-like receptor and contributes to the maintenance of proliferation of EBV-infected primary human B lymphocytes. LMP-1 is targeted to the plasma membrane, where it binds TRAF, TRADD, and JAK molecules to activate NF-kappaB-, AP-1-, and STAT-dependent pathways as does CD40. Yet LM...
متن کاملThe Epstein-Barr virus latent membrane protein 1 induces expression of the epidermal growth factor receptor.
The Epstein-Barr virus (EBV)-encoded LMP1 protein is an important component of the process of transformation by EBV. LMP1 is essential for transformation of B lymphocytes, most likely because of its profound effects on cellular gene expression. Although LMP1 is expressed in the majority of nasopharyngeal carcinoma (NPC) tumors, the effect of LMP1 on cellular gene expression and its contribution...
متن کاملEpstein-Barr virus regulates STAT1 through latent membrane protein 1.
This study shows a mechanism for the increase of signal transducer and activator of transcription 1 (STAT1) in Epstein-Barr virus-immortalized cells. Latent membrane protein 1 (LMP-1) expression was sufficient to induce STAT1 expression, DNA binding, and transcriptional activity. LMP-1-expressing cells can induce an increase in STAT1 expression in LMP-negative cells in the same culture, suggest...
متن کاملEpstein-Barr virus latent membrane protein-1 (LMP-1) expression in oral squamous cell carcinoma.
OBJECTIVES Epstein-Barr virus (EBV) is frequently associated with malignant cell transformation through the action of the oncoprotein latent membrane protein-1 (LMP-1). The present study aimed to determine the presence of EBV in oral squamous cell carcinomas (OSCCs) and the expression of LMP-1 in neoplastic cells of EBV-positive OSCCs. STUDY DESIGN/METHODS In a retrospective study of 78 OSCCs...
