Article Abstract

To control the spread of the disease, the Zika virus (ZIKV), a flavivirus infection spread by mosquitoes and common in across the world, needs to be accurately and promptly diagnosed. This endeavour gets challenging when early-stage illnesses have low viral loads. As a result, we have created a biosensor based on surface-enhanced Raman scattering (SERS) for the quick, accurate, and timely diagnosis of the Zika virus. In this study, a glass coverslip was coated with silver nanoislands, which were then utilized as the surface for creating the sensing platform. Silver nanoislands exhibit strong plasmonic activity and good conductive characteristics. It enhances the Raman signals as a result and gives the SERS platform an appropriate surface. The created platform has been applied to Zika virus detection. With a limit of detection (LOD) of 0.11 ng/mL, the constructed sensor exhibits a linear range from 5 ng/mL to 1000 ng/mL. Hence, even at the nanogram scale, this technique may be a major improvement over clinical diagnosis approaches for making proper, precise, and accurate Zika virus detection.

Introduction: The Zika virus (ZIKV) envelope (E) protein is critical for viral replication and host interactions. Although glycosylation of the E protein is known to influence viral infectivity and immune evasion, the specific functional roles of E protein glycosylation in ZIKV infectivity in mosquito cells remain unclear.

Methods: In this study, we generated a deglycosylation mutant ZIKV with a T156I substitution in the E protein and investigated its effects on viral replication and viral-host interactions in mosquito C6/36 cells.

Background: Serum and other blood-derived products are widely used in biomedical and biopharmaceutical processes, especially for the production of vaccines or cell therapeutic applications. To ensure quality and safety, each serum lot undergoes testing for sterility to minimize the risk of disease transmission. A currently performed standard procedure is gamma-irradiation of serum for effectively killing pathogens.

Manipulating Zika virus RNA tertiary structure for developing tissue-specific attenuated vaccines.

Traditional live attenuated vaccines (LAVs) are typically developed through serial passaging or genetic engineering to introduce specific mutations or deletions. While viral RNA secondary or tertiary structures have been well-documented for their multiple functions, including binding with specific host proteins, their potential for LAV design remains largely unexplored. Herein, using Zika virus (ZIKV) as a model, we demonstrate that targeted disruption of the primary sequence or tertiary structure of a specific viral RNA element responsible for Musashi-1 (MSI1) binding leads to a tissue-specific attenuation phenotype in multiple animal models.

Mumps virus infection triggers early pro-inflammatory responses and impairs Leydig and Sertoli cell function in an ex vivo human testis model.

Study Question: What is the direct effect of mumps virus (MuV) replication within the human testis on the tissue innate immune responses and testicular cell functions?

Summary Answer: MuV induces an early pro-inflammatory response in the human testis ex vivo and infects both Leydig cells and Sertoli cells, which drastically alters testosterone and inhibin B production.

What Is Known Already: Despite widespread vaccination efforts, orchitis remains a significant complication of MuV infection, especially in young men, which potentially results in infertility in up to 87% of patients with bilateral orchitis. Our understanding of MuV pathogenesis in the human testis has been limited by the lack of relevant animal models, impairing the development of effective treatments.

Arboviral infections, particularly Dengue and Zika, continue to rise at an alarming rate, with both viruses declared global health emergencies in 2024 and 2016, respectively. The NS5 RNA-dependent RNA polymerase (RdRp) of dengue virus (DENV) and Zika virus (ZIKV) is highly conserved, making nucleoside-based RdRp inhibitors a promising strategy for antiviral development. While nucleoside analogs have shown strong clinical potential, challenges such as cell permeability, the efficiency of triphosphate conversion, degradation, and mitochondrial toxicity remain.
