The Epstein-Barr virus (EBV) is a common virus in humans and the most common causative agent of Infectious Mononucleosis. EBV primary infection has recently risen in some countries and children below 2 years of age are highly susceptible. The clinical manifestations in children with EB virus infection involve multiple systems, causing severe illness, meaning attention should be paid during diagnosis and treatment. This single institution based retrospective study was carried out with the aim of estimating the overall prevalence of EBV infection and identifying high-risk age group among children. This study include total 253 patients under 15 years of age found to be positive for EBV DNA by serum PCR who were admitted to the Pediatrics Department of Renmin Hospital,(Shiyan, China) during a 4-year period from 2014 to 2017. Patients were divided into three groups; 0-<4years, 4-<6years and 6-<15years. We then calculated the percentage and prevalence of EBV DNA-positive cases. The yearly EBV prevalence rate was 4.99 per 1000 admissions in 2014, 6.97 per 1000 admissions in 2015, 10.42 per 1000 admissions in 2016, and 12.16 per 1000 admissions in 2017. Out of 253 EBV-positive cases, those under 4 years had the highest rate of EBV infection (74.7%). The rate drops to 11.06% in the 4-6 years group, and was 14.22% in the 6-15 years group. Those between 6 months and 1 year are those at the highest risk. The rate of hospital admission of children due to EBV infection is increasing day by day. Children under 4 years of age are highly susceptible to infection and children of age between 6 months and 1 year are the high-risk group for EBV infection.

Background: Previous investigations into the causal relationship between infections and systemic lupus erythematosus (SLE) have yielded controversial results. This study delves into the bidirectional causal relationships between various infectious agents and SLE, employing two-sample Mendelian randomization (MR) from an immunological perspective.
Methods: Utilizing genome-wide association study (GWAS) data for 46 antibody-mediated immune responses (AMIRs) to 13 pathogens and three distinct SLE datasets, we employed Bayesian Weighted MR (BWMR) and inverse variance weighted (IVW) methods to ascertain causal links, supplemented by meta-analysis to resolve inconsistencies.

As a ubiquitous human pathogen, the Epstein-Barr virus (EBV) has established lifelong persistent infection in about 95% of the adult population. The EBV infection is associated with approximately 200,000 human cancer cases and 140,000 deaths per year. The presence of EBV in tumor cells provides a unique advantage in targeting the viral genome (also known as episome), to develop anti-cancer therapeutics.

Background: The Epstein-Barr virus (EBV) is intricately linked to a range of human malignancies, with EBV latent membrane protein 2A (LMP2A) emerging as a potential target antigen for immunotherapeutic strategies in the treatment of nasopharyngeal carcinoma (NPC).
Methods: The modified vaccinia virus Ankara (MVA) is universally used in vector vaccine research because of its excellent safety profile and highly efficient recombinant gene expression. Here, we constructed a novel MVA-LMP2A recombinant virus and investigated its specific immune response induction and oncolytic effect.

Gastric cancer (GC) is one of the most common cancers in the world. It is a multi-factorial disease influenced by both genetic and environmental factors such as diet, obesity, radiation exposure, and infectious agents. Viral infections usually lead to chronic inflammation, which can initiate the development of cancers.
