Nearly one-third of countries worldwide have reported cases of Dengue virus (DENV) and Zika virus (ZIKV) infections, highlighting the significant threat these viruses pose to global public health. As members of the Flavivirus genus within the Flaviviridae family, DENV and ZIKV have demonstrated the ability to infect a wide range of cell lines from multiple species in vitro. However, the range of susceptible animal models is notably limited, and field studies indicate that their capacity to infect host organisms is highly restricted, with a very narrow range of target cells in vivo. The virus's ability to hijack host cellular machinery plays a crucial role in determining its cellular and species specificity. In this review, we examine how DENV and ZIKV exploit host cells to facilitate their replication, offering new insights that could inform the development of antiviral drugs and therapeutic targets.

Many virus species, including Ebola virus, Marburg virus, SARS-CoV-2, dengue virus (DENV) and Zika virus (ZIKV), exploit CD209 and CD209L as alternative or attachment receptors for viral cis- or trans-infection. Thus, CD209 and CD209L may be critical targets for the development of therapeutic monoclonal blocking antibody drugs to disrupt the infection process caused by multiple viruses. Here, we produced a human chimeric monoclonal blocking antibody that simultaneously blocks CD209 and CD209L, namely 7-H7-B1.

Zika virus (ZIKV) and dengue virus (DENV) are two major mosquito-borne flaviviruses that pose a significant threat to the global public health system, particularly in tropical regions. The clinical outcomes related to these viral pathogens can vary from self-limiting asymptomatic infections to various forms of life-threatening pathological conditions such as haemorrhagic disorders. In addition to the direct effects of the viral pathogens, immune processes play also a significant function in the development of diseases mediated by ZIKV and DENV.

Background: Gestational Zika virus (ZIKV) infection is associated with the development of congenital Zika syndrome (CZS), which includes microcephaly and fetal demise. The magnitude and quality of orthoflavivirus-specific humoral immunity have been previously linked to the development of CZS. However, the role of ZIKV NS1-specific humoral immunity in mothers and children with prenatal ZIKV exposure and CZS remains undefined.

Flaviviruses utilize the cellular endoplasmic reticulum (ER) for all aspects of their lifecycle. Genome replication and other viral activities take place in structures called replication organelles (ROs), which are invaginations induced in the ER membrane. Among the required elements for RO formation is the biogenesis of viral nonstructural proteins NS4A and NS4B.

Article Synopsis
- In-utero exposure to Zika virus (ZIKV) can result in severe outcomes like miscarriage and congenital Zika syndrome, prompting a study on the infection rates among pregnant women from February to April 2022.
- Researchers tested 200 pregnant women for ZIKV antibodies and found that 16.5% had ZIKV IgM, 10% had IgG, and 23% had neutralizing antibodies, indicating various stages of infection and immunity.
- The study also revealed that recent ZIKV infections were more common in sexually active women aged 20-29, with higher infection risks in first trimester and grand-multiparous women, although no significant link was found between ZIKV and specific pregnancy trimest
