Prader-Willi syndrome (PWS) is a complex neurobehavioral disorder that results from loss of function of 10 clustered, paternally expressed genes in a 1.5-Mb region of chromosome 15q11-q13. Many of the primary PWS region genes appear to have nuclear RNA regulatory functions, suggesting that multiple genetic pathways could be secondarily affected in PWS.

Epstein-Barr virus (EBV) establishes a lifelong latent infection in host B cells and is associated with the development of a variety of malignancies. The viral LMP2A protein mediates viral latency by mimicking a constitutively activated B-cell receptor (BCR). In vivo LMP2A provides developmental and survival signals to BCR-negative B cells, allowing them to survive in peripheral lymphoid organs.

The latent membrane protein 2A (LMP2A) of Epstein-Barr virus (EBV) is an important mediator of viral latency in infected B-lymphocytes. LMP2A inhibits B-cell receptor (BCR) signaling in vitro and allows for the survival of BCR-negative B cells in vivo. In this study, we compared gene transcription in BCR-activated B cells from non-transgenic and LMP2A Tg6 transgenic mice.

Epstein-Barr virus (EBV) is associated with the development of a variety of malignancies, including Hodgkin lymphoma. One of the few viral transcripts expressed in EBV-positive Hodgkin/Reed-Sternberg (HRS) cells of Hodgkin lymphoma is latent membrane protein 2A (LMP2A). This viral protein blocks B-cell receptor (BCR)-signaling in vitro.
