Epstein-Barr virus (EBV) is a prevalent oncogenic estimated to infect greater than 90% of the world's population. Following initial infection, it establishes latency in host B cells. EBV has developed multitude techniques avoid detection by immune system and establish lifelong infection. T cells, as important contributors cell-mediated immunity, make an attractive target for these immunoevasive strategies. Indeed, evolved numerous mechanisms modulate cell responses. For example, can augment expression programmed death ligand-1 (PD-L1), which inhibits function, downregulates interferon response, strong impact on regulation. It also modulates interleukin secretion influence major histocompatibility complex (MHC) presentation. In addition facilitating persistent immunoregulatory have significant implications evasion response tumor This review dissects through avoids cells discusses how play into survival. concludes with overview cancer treatments targeting setting EBV-associated malignancy.

This comprehensive review delves into the intricate role of programmed cell death in Epstein-Barr virus (EBV)-associated malignancies, focusing on sophisticated interplay between viral mechanisms and host's immune response. The central objective is to unravel how EBV exerts control over pathways such as apoptosis, ferroptosis, autophagy, thereby fostering its persistence oncogenic potential. By dissecting these mechanisms, seeks identify therapeutic strategies that could disrupt EBV's manipulation pathways, enhancing recognition opening new avenues for targeted treatment. A deeper understanding molecular underpinnings influence not only enriches field oncology but also pinpoints targets drug development. Furthermore, insights gleaned from this catalyze design vaccines aimed at preventing infection or curtailing impact. Innovatively, synthesizes recent discoveries multifaceted roles non-coding RNAs cellular signaling modulating within context infection. consolidating current knowledge identifying areas where lacking, it lays groundwork future research lead significant advancements vaccine development interventions EBV-related cancers. underscores critical necessity ongoing investigation complex host with ultimate goal patient outcomes EBV-associated diseases.

The tegument is the structure between envelope and nucleocapsid of herpesvirus particles. Viral (and cellular) proteins accumulate to create layers tegument. Some Epstein-Barr virus (EBV) are conserved widely in Herpesviridae, but others shared only by members gamma-herpesvirus subfamily. As interface nucleocapsid, functions virion morphogenesis budding during progeny production. When a particle enters cell, enzymes such as kinase deubiquitinase, transcriptional activators released from promote infection. Moreover, some EBV involved oncogenesis. Here, we summarize roles proteins, comparison those other herpesviruses.

Epstein-Barr virus (EBV) causes multiple human cancers, including B-cell lymphomas. In cell culture, EBV converts healthy B-cells into immortalized ones that grow continuously, which model post-transplant Constitutive signaling from two cytoplasmic tail domains of the oncogene latent membrane protein 1 (LMP1) is required for this transformation, yet there has not been systematic analysis their host gene targets. We identified only proximal domain survival these EBV-immortalized cells and its loss triggers apoptosis. key LMP1 target genes, whose abundance changed significantly with signals, or were instead upregulated in response to switching on by one both an EBV-uninfected model. These included major anti-apoptotic factors necessary EBV-infected survival. Bioinformatics analyses clusters genes respond differently either domains.
