Special Issue Information
Dear Colleagues,
The viral genome is typically categorized into structural and non-structural proteins. Structural proteins form the core components of the viral particle, or virion, and play key roles in the early stages of infection, such as viral entry. In contrast, non-structural proteins are internal viral components that are primarily involved in the replication cycle. These proteins often include proteases, polymerases, transcription factors, or molecules that inhibit innate immunity signaling pathways, ultimately enabling the virus to bypass host defense mechanisms and redirect cellular metabolism toward synthesizing viral components, including genomic material and both structural and non-structural proteins, to produce the viral progeny.
Non-structural proteins are generally synthesized within the host cell and remain less exposed to the immune system, meaning that they are predominantly presented to T cells rather than eliciting both B and T cell responses like structural proteins. Due to their critical roles in the viral life cycle, non-structural proteins often feature highly conserved enzymatic domains, which are less subject to immune pressure compared to structural proteins. This conservation makes non-structural proteins attractive targets for vaccine and therapeutic development.

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. Viruses is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). 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.
