Special Issue Information
Dear Colleagues,
Tripartite Motif (TRIM) proteins belong to a large family of E3-ubiquitin ligases, many of which have antiviral activity. TRIMs have long been known for their functions as direct restriction factors; however, they can also act indirectly by promoting the induction of antiviral type-I Interferons (IFN-I). TRIM activity has been linked to a variety of cellular functions, including the regulation of immune signaling, cell cycle, apoptosis, autophagy, and many others. Studies are uncovering unrecognized mechanisms of TRIM activity, including the direct ubiquitination of viral proteins that may balance proviral and antiviral functions, and may perform this via the synthesis of unconventional polyubiquitin chains. It is still unclear what mechanism balances the contradictory roles of TRIMs at the physiological level. The dual roles of TRIMs and their involvement in multiple cellular functions have made it virtually impossible to use them as feasible druggable targets. The generation of TRIM knockouts in cells and animals using CRISPR technology has led to an exponential advance in our understanding of TRIM functions. In this Special Issue, we will explore novel aspects of TRIM function in relation to virus infection, including proviral and antiviral roles, antagonism, and pathogenesis. New comprehensive studies may help identify novel strategies to modulate TRIM activity for therapeutic interventions.

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.
