Special Issue Information
Dear Colleagues,
The last decade has witnessed a remarkable increase in the number of alignment-free, machine learning-based approaches for the prediction of antimicrobial peptides. The accuracy of shallow and deep learning methods to discriminate AMPs from non-AMPs has reached 95% or more. Once a sequence is identified as antimicrobial, its specific activity, target pathogen and MIC must be determined. Furthermore, antimicrobial peptides are also able to penetrate cells and activate autophagy in mammalian cells, as well as to modulate the immune system. In summary, the activities embedded within these peptides include anti-viral, anti-fungal, anti-parasite, anti-bacterial, pro-autophagy and immunomodulator. Such multi-functionality imposes the need to further characterize these peptides to evaluate which activities are present, not only out of curiosity, but also as a requirement if these peptides are aimed to be used as pharmaceuticals. Thus, further developments of these predictors and experimental systems are required to match the current development of the field.
Methodological challenges to match this increasing need to further characterize antimicrobial peptides include the lack of a profound analysis of the available data, representation aspects of both shallow and deep models and high-throughput assays. A well-known drawback of machine-learning methods is the lack of negative experimentally validated sets. The development of high-throughput experiments assessing the different activities of antimicrobial peptides will be of extreme value.
This Special Issue of Antibiotics invites authors to publish original research including peptide data analysis, methodological aspects of machine learning-based approaches and high-throughput assays intended to achieve the abovementioned goal.

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. Antibiotics 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 2900 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.
