Special Issue Information

Dear Colleagues,

Viral diseases represent a significant challenge to human health in the context of modern medicine, manifesting as a wide range of acute infections, chronic diseases, and virus-associated malignancies. The severity of pathogenesis is influenced by multiple factors, including viral and host characteristics. Immunocompromised patients (e.g., individuals living with HIV, post-transplant pharmacologic immunosuppression, or congenital diseases) are particularly vulnerable to opportunistic diseases, necessitating intensive interventions and distinct vaccination schedules. It is therefore imperative that we investigate the complex dynamics between viral pathogens and host immune responses in both healthy and immunocompromised individuals. This Special Issue will primarily focus on the mechanisms by which viruses evade immune recognition and counteract host defences, including interferon signalling and antibody responses. It is essential that we examine key molecular interactions, including the role of viral proteins in modulating host–cell functions, in order to gain insights into how SARS-CoV-2 and other viruses influence immune pathways. Furthermore, studies examining potential therapeutic strategies for the enhancement of immune responses and the targeting of viral components are urgently required. Authors are encouraged to consider insights that are applicable to other viral infections beyond SARS-CoV-2 and viral co-infections. This will contribute to a deeper understanding of virus–host interactions, which is essential in informing vaccine development and treatment approaches in the context of emerging infectious diseases. This Special Issue will provide a comprehensive and up-to-date overview of the vast and rapidly evolving field of virus–host interactions, through both original research and reviews, with a particular focus on the molecular insights that can inform public health strategies to combat viral threats.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Orthoflavivirus encephalitidis (tick-borne encephalitis virus, TBEV) is of high concern due to its ability to cause severe neurological manifestations. Despite the fact that the role of NS1 proteins from various mosquito-borne flaviviruses in pathogenesis and their ability to affect human endothelial permeability have been investigated, TBEV NS1 has thus far been insufficiently studied. In this study, human endothelial permeability was assessed using TEER and transwell permeability assays. Signaling pathways were determined by RNAseq. The ability of the NS1 protein of TBEV to affect human endothelial permeability was investigated for the first time. It was shown that recombinant TBEV NS1 produced in eucaryotic cells directly affected human lung microvascular endothelial cells (HLMVECs) in vitro but not human umbilical vein endothelial cells (HUVECs). It was indicated that TBEV NS1 induced endothelial hyperpermeability of HLMVECs through activating TNF-α and other inflammatory signaling pathways. Full article
