Article Abstract
Epstein Barr virus (EBV) was discovered 60 years ago as the first candidate human tumor virus. Since then, we have realized that this human γ-herpesvirus establishes persistent infection in the majority of adult humans but fortunately causes EBV associated diseases only in a few individuals. This is an incredible success story of the human immune system, which controls EBV infection and its transforming capacity for decades after initial virus encounter. A better understanding of this immune control would not only benefit patients with EBV associated malignancies but could also provide clues on how to establish such a potent, mostly cell-mediated immune control against other pathogens and tumors. However, the functional relevance of EBV specific immune responses can only be addressed in vivo and mice with reconstituted human immune system components (humanized mice) constitute a small animal model that can be infected with EBV, recapitulates some aspects of virus associated tumorigenesis, and mounts mostly cell-mediated immune responses against EBV. This chapter will summarize the insights into EBV immunobiology that have already been gained in humanized mouse models and provide an outlook into promising future avenues to further characterize EBV infection, immune control, and associated pathologies in vivo.

African Swine Fever (ASF), caused by the highly contagious African swine fever virus (ASFV), poses a significant threat to domestic and wild pigs worldwide. Despite its limited host range and lack of zoonotic potential, ASF has severe socio-economic and environmental consequences. Current control strategies primarily rely on early detection and culling of infected animals, but these measures are insufficient given the rapid spread of the disease.

In pig production, weaning is a critical period where piglets face several environmental stressors. This transition leads to a significant growth reduction and can result in digestive disorders, including diarrhea. To formulate a feed that meets zinc (Zn) and copper (Cu) requirements during the weaning period while minimizing their release into the environment, it became evident that a more bioavailable micro-mineral supplement is necessary.

Purpose Of Review: Plasma metagenomic next-generation sequencing (mNGS) enables detection of microbial cell-free deoxyribonucleic acid (mcfDNA) in blood without the need for culture or organism-specific primers. Here, we review clinical performance, methodological variability, and real-world application of plasma mNGS for infectious disease diagnosis in immunocompromised hosts (ICHs).
Recent Findings: Plasma mNGS has rapidly gained attention as a novel diagnostic tool for infections in ICHs, offering broad-range pathogen detection from a noninvasive blood sample.
Design of Two Randomized, Placebo-Controlled, Phase 3 Trials of Deucravacitinib, an Oral, Selective, Allosteric TYK2 Inhibitor, in Systemic Lupus Erythematosus.

Background And Objectives: Deucravacitinib, a first-in-class, oral, selective, allosteric tyrosine kinase 2 inhibitor, demonstrated efficacy across the primary endpoint and all key secondary endpoints in the phase 2 PAISLEY SLE trial in patients with active systemic lupus erythematosus (SLE). Here, we describe 2 phase 3 trials [POETYK SLE-1 (NCT05617677), POETYK SLE-2 (NCT05620407)] which will assess the efficacy and safety of deucravacitinib in patients with active SLE. These phase 3 trials have been designed to replicate the successful elements of the phase 2 trial, including its glucocorticoid-tapering strategy and disease activity adjudication.
