Special Issue Information
Dear Colleagues,
Viruses need to engage host factors to infect, replicate and assemble new pathogens. Several genome-wide siRNA or CRISPR screening studies have also identified that host factors are critical for virus infection and growth. In addition, post-translation modifications (PTMs), such as phosphorylation, ubiquitylation and SUMOylation, have been discovered to be critical for many virus life cycles. For example, Ebola, CMV and EMCV utilize SUMOylation to inhibit anti-viral intrinsic and innate immunity via, e.g., reducing interferon production and inhibiting STAT1/3, PML, IRFs and NFkB. SARS-CoV-2 also inhibits the host IFN signaling pathway to repress the host immune response for its replication. Furthermore, many viral infections and replications can manipulate the host factors to ensure their propagation and survival. Herpes simplex virus-1 (HSV-1) infection results in a three-fold decrease in the modification of over 100 cellular proteins, including antiviral promyelocytic leukemia (PML) nuclear bodies. Therapeutics targeting host–virus interactions could potentially present a potential effective and broad-spectrum treatment modality for viruses such as COVID-19 and influenzas, as exemplified in the cases of methylprednisolone and rSIFN-co with even more potential benefits, such as an anti-coinfections effect. A comprehensive understanding of host–virus protein interactions and modifications in viral infection would significantly improve our knowledge and approaches against viral infections and novel 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.
