Dear Colleagues,

Interferons (IFNs) are a family of pleiotropic cytokines, which play a key role in a wide range of biological processes. In addition to the well-described antiviral actions, IFNs were quickly recognized as central coordinators of innate immune responses during tumorigenesis. However, evidence has emerged in recent years suggesting that IFNs may also trigger immune suppressive mechanisms in cancer-promoting malignant progression and resistance to therapies. Depending on the stimulus, IFNs can be produced by almost any cell type, including fibroblasts and leucocytes, as well as cancer cells, through the engagement of distinct pattern recognition receptors (PRRs). In this regard, danger-associated molecular patterns (DAMPs) released upon cellular stress or therapy-induced cell death represent key inducers of type I IFNs in the tumor microenvironment. Among sensing pathways, a major role is played by the cGAS-STING pathway, which detects cytoplasmic DNA after DNA damage. A growing amount of evidence indicates that the cGAS-STING pathway has a role in regulating other important cellular processes such as autophagy, cell survival, and senescence.

For this Special Issue of Biology, we invite authors to submit original research papers, review articles, commentaries, and perspective pieces on recent progress in the broad topic of Type-I-IFNs in cancer diseases, including cancers transformed by an oncogenic virus (i.e., HPV, EBV), highlighting their dichotomous role and the potential therapeutic benefit of type I IFN pathway modulation.

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. Biology 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 2700 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.
