Epstein-Barr virus (EBV) infects more than 90% of the human population worldwide and establishes lifelong infection in hosts by switching between latent lytic infection. EBV latency can be reactivated under appropriate conditions, leading to expression viral genes production infectious progeny viruses. reactivation involves crosstalk various factors signaling pathways, subsequent complicated virus-host interplays determine whether continues propagate. However, detailed mechanisms underlying these processes remain unclear. In this review, we summarize critical regulating associated mechanisms. This encompasses transcription post-transcriptional regulation immediate-early (IE) genes, functions on DNA replication production, through which proteins disrupt inhibit host's innate immune response, host that modulate reactivation. Finally, explore potential applications novel technologies studying reactivation, providing insights into investigation governing development anti-EBV therapeutic strategies.

The Epstein-Barr virus (EBV) infects nearly 90% of adults globally and is linked to over 200,000 annual cancer cases. Immunocompromised individuals from conditions such as primary immune disorders, HIV, or posttransplant immunosuppressive therapies are particularly vulnerable because EBV’s transformative capability. EBV remodels B cell metabolism support energy, biosynthetic precursors, redox equivalents necessary for transformation. Most EBV-driven metabolic pathways center on mitochondria. However, how regulates mitochondrial function fluxes remains unclear. Here, we show that boosts cardiolipin (CL) biosynthesis, essential cristae biogenesis, via nuclear antigen 2/MYC-induced CL enzyme transactivation. Pharmacological CRISPR genetic analyses underscore the essentiality biosynthesis in EBV-transformed cells. Metabolomic isotopic tracing highlight CL’s role sustaining respiration, one-carbon metabolism, aspartate synthesis. Disrupting destabilizes matrix enzymes pivotal these pathways. We demonstrate EBV-induced a therapeutic target, offering synthetic lethal strategies against EBV-associated malignancies.

ABSTRACT Epstein–Barr virus (EBV) is the first human cancer‐causing viral pathogen to be discovered; it has been epidemiologically associated with a wide range of diseases, including cancers, autoimmunity, and hyperinflammatory disorders. Its evolutionary success underpinned by coordinated expression transcription factors (EBV nuclear antigens), signaling proteins latent membrane proteins), noncoding RNAs, which orchestrate cell transformation, immune evasion, dissemination. Each those activities entails significant metabolic rewiring, achieved subversion key host regulators such as mammalian target rapamycin (mTOR), MYC, hypoxia‐inducible factor (HIF). In this review, we systemically discuss how EBV‐encoded regulate metabolism achieve persistence propagation, well potential research questions directions in EBV‐driven metabolism.

Epstein-Barr virus (EBV), a member of the γ-herpesvirus family, is one most prevalent and persistent human viruses, infecting up to 90% adult population globally. EBV's life cycle includes primary infection, latency, lytic reactivation, with primarily B cells epithelial cells. This has evolved sophisticated strategies evade both innate adaptive immune responses, thereby maintaining lifelong presence within host. persistence facilitated by expression latent genes such as EBV nuclear antigens (EBNAs) membrane proteins (LMPs), which play crucial roles in viral latency oncogenesis. In addition their well-known several types cancer, including nasopharyngeal carcinoma B-cell lymphomas, recent studies have identified pathogenic autoimmune diseases multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus. review highlights intricate interactions between host system, underscoring need for further research develop effective therapeutic preventive against EBV-associated diseases.

Abstract Epstein-Barr virus (EBV) infection has long been associated with the development of multiple sclerosis (MS). Patients MS have elevated titres EBV-specific antibodies in serum and show signs CNS damage only after EBV infection. Regarding CD8+ T cells, an but ineffective response to was suggested patients, who present a broader MHC-I-restricted T-cell receptor beta chain (TRB) repertoire compared controls. It is not known whether this altered could be subject dynamic changes, e.g. by approved therapies, it specific for MS. Peripheral blood TRB samples (n = 1317) healthy donors 409), patients 710) before treatment, neuromyelitis optica spectrum disorder 87), MOG antibody-associated disease (MOGAD) 64) Susac’s syndrome 47) were analysed. Apart from MS, none evaluated diseases presented anti-EBV repertoire. In undergoing autologous haematopoietic stem-cell transplantation, reactivation coincided sequence matches.

Long COVID following SARS-CoV-2 and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) infectious mononucleosis (IM) are two examples of post-viral syndromes. The identification risk factors predisposing patients to developing maintaining post-infectious syndromes may help uncover their underlying mechanisms. majority with ME/CFS report illnesses before the onset ME/CFS, 30% cases due IM caused by Epstein–Barr virus. After IM, one study found 11% adults had at 6 months 9% 1 year. Another adolescents 13% 7% 12 respectively. However, it is unclear which variables potential contributing development maintenance because few prospective studies have collected baseline data triggering illness. current article provides an overview a that included pre-illness predictors in diverse group college students who were enrolled IM.

Targeted protein degradation (TPD) modulates function beyond inhibition of enzyme activity or protein-protein interactions. Most degraders by proximity induction, and directly bridge an E3 ligase with the target to be degraded. However, many proteins might not addressable via proximity-based degraders, other challenges, such as resistance acquisition, exist. Here, we identified pseudo-natural products derived from (-)-myrtanol, termed iDegs, that inhibit induce immunomodulatory indoleamine-2,3-dioxygenase 1 (IDO1) a distinct mechanism. iDegs unique conformational change and, thereby, boost IDO1 ubiquitination cullin-RING CRL2
