In this review, we provide an overview of the intricate host-virus interactions that have emerged from the study of SARS-CoV-2 infection. We focus on the antiviral mechanisms of interferon-stimulated genes (ISGs) and their modulation of viral entry, replication, and release. We explore the role of a selection ISGs, including BST2, CD74, CH25H, DAXX, IFI6, IFITM1-3, LY6E, NCOA7, PLSCR1, OAS1, RTP4, and ZC3HAV1/ZAP, in restricting SARS-CoV-2 infection and discuss the virus's countermeasures. By synthesizing the latest research on SARS-CoV-2 and host antiviral responses, this review aims to provide a deeper understanding of the antiviral state of the cell under SARS-CoV-2 and other viral infections, offering insights for the development of novel antiviral strategies and therapeutics.

Background: SHEN26 (ATV014) is an oral RNA-dependent RNA polymerase (RdRp) inhibitor with potential anti-SARS-CoV-2 activity. Safety, tolerability, and pharmacokinetic characteristics were verified in a Phase I study. This phase II study aimed to verify the efficacy and safety of SHEN26 in COVID-19 patients.

Bacterial meningitis is an increasingly rare disease that carries significant morbidity and mortality. We describe the case of a 38-year-old male with a past medical history of pituitary macroadenoma with prior endonasal surgeries on prednisone therapy daily for resultant hypopituitarism and juvenile myoclonic epilepsy on lamotrigine daily who was transferred to an academic tertiary emergency department due to concern for developing pituitary apoplexy. At the outside emergency department, the patient presented complaining of sudden onset severe headache.

Background & Aims: Hepatitis B reactivation (HBVr) can occur due to a variety of immune-modulating exposures, including multiple drug classes and disease states. Antiviral prophylaxis can be effective in mitigating the risk of HBVr. In select cases, clinical monitoring without antiviral prophylaxis is sufficient for managing the risk of HBVr.

Human Metapneumovirus (HMPV) is a re-emerging respiratory pathogen causing significant morbidity and mortality, particularly among young children, the elderly, and immunocompromised individuals. First identified in 2001, HMPV has since been recognised as a leading cause of acute respiratory tract infections (ARTIs) worldwide. Its transmission occurs through droplets, direct contact, and surface contamination, with crowded spaces and healthcare facilities serving as key environmental amplifiers.

The type I interferon (IFN-I) response is a critical component of the immune defense against various viral pathogens, triggering the expression of hundreds of interferon-stimulated genes (ISGs). These ISGs encode proteins with diverse antiviral functions, targeting various stages of viral replication and restricting infection spread. Beyond their antiviral functions, ISGs and associated immune metabolites have emerged as promising broad-spectrum biomarkers that can differentiate viral infections from other conditions.
