Using microbes as a key tool to unravel the mechanism of autophagy and the functions of the ATG proteins
Mario Mauthe and Fulvio ReggioriMicrobes have served to discover and characterize unconventional functions of the ATG proteins, which are uncoupled from their role in autophagy. In our recent study, we have taken advantage of viruses as a screening tool to determine the extent of the unconventional functions of the ATG proteome and characterize one of them.
Autophagy: one more Nobel Prize for yeast
Zimmermann et al.The recent announcement of the 2016 Nobel Prize in Physiology or Medicine, awarded to Yoshinori Ohsumifor the discoveries of mechanisms governing autophagy, underscores the importance of intracellular degradation and recycling. Here we provide a quick historical overview that mirrors both the importance of autophagy as a conserved and essential process for cellular life and death as well as the crucial role of yeast in its mechanistic characterization.
Physiology, phylogeny, and LUCA
Martin et al.Genomes record their own history. But if we want to look all the way back to life’s beginnings some 4 billion years ago, the record of microbial evolution that is preserved in prokaryotic genomes is not easy to read. The classical approach has been to look for genes that are universally distributed. Another approach is to make all trees for all genes, and sift out the trees where signals have been overwritten by lateral gene transfer. What is left ought to be ancient. If we do that, what do we find?
Sexually transmitted infections: old foes on the rise
Carmona-Gutierrez et al.Sexually transmitted infections (STIs) are commonly spread via sexual contact. It is estimated that one million STIs are acquired every day worldwide. Besides their impact on sexual, reproductive and neonatal health, they can cause disastrous and life-threatening complications if left untreated. In addition to this personal burden, STIs also represent a socioeconomic problem, deriving in treatment costs of tremendous proportions. Despite a substantial progress in diagnosis, treatment and prevention, the incidence of many common STIs is increasing, and STIs continue to represent a global public health problem and a major cause for morbidity and mortality. With this Special Issue, Microbial Cell provides an in-depth overview of the eight major STIs, covering all relevant features of each infection.

Peer-reviewed, open-access research using unicellular organisms (and multicellular microorganisms) to understand cellular responses and human disease.
The journal (founded in 2014) is led by its Editors-in-Chief Frank Madeo, Didac Carmona-Gutierrez, and Guido Kroemer
Microbial Cell has been publishing original scientific literature since 2014, and from the very beginning has been managed by active scientists through an independent Publishing House (Shared science Publishers). The journal was conceived as a platform to acknowledge the importance of unicellular organisms, both as model systems as well as in the biological context of human health and disease.
Ever since, Microbial Cell has very positively developed and strongly grown into a respected journal in the unicellular research community and even beyond. This scientific impact is reflected in the yearly number of citations obtained by articles published in Microbial Cell, as recorded by the Web of Science (Clarivate, formerly Thomson/Reuters):
The scientific impact of Microbial Cell is also mirrored in a series of milestones:
2015: Microbial Cell is included in the Emerging Sources Citation Index (ESCI), a selection of developing journals drafted by Clarivate Analytics based on the candidate’s publishing standards, quality, editorial content, and citation data. Note: As an ESCI-selected journal, Microbial Cell is currently being evaluated in a rigorous and long process to determine an inclusion in the Science Citation Index Expanded (SCIE), which allows the official calculation of Clarivate Analytics’ impact factor.
2016: Microbial Cell is awarded the so-called DOAJ Seal by the selective Directory of Open Access Journals (DOAJ). The DOAJ Seal is an exclusive mark of certification for open access journals granted by DOAJ to journals that adhere to outstanding best practice and achieve an extra high and clear commitment to open access and high publishing standards.
2017: Microbial Cell is included in Pubmed Central (PMC), allowing the archiving of all the journal’s articles in PMC and PubMed.
2019: Microbial Cell is indexed in the prestigious abstract and citation database Scopus after a thorough selection process. This also means that Microbial Cell obtains, for the first time, an official Scopus CiteScore as well as an official journal ranking in the Scimago Journal and Country Ranking.
2022: Microbial Cell’s CiteScore reaches a value of 7.2 for the year 2021, positioning Microbial Cell among the top microbiology journals (previously available CiteScores: 2019: 5.4; 2020: 5.1).
2022: Microbial Cell is indexed in the highly selective Science Citation Index Expanded™, which covers approx. 9,500 of the world’s most impactful journals across 178 scientific disciplines. In their journal selection and curation process, Clarivate´s editors apply 24 ‘quality’ criteria and four ‘impact’ criteria to select the most influential journals in their respective fields. This selection is also a pre-requisite for inclusion in the JCR, which features the impact factor.
2022: Microbial Cell is listed in the Journal Citation Reports™ (JCR), and obtains its first official Journal Impact Factor™ (JIF) for the year 2021: 5.316.

Staphylococcus aureus type I signal peptidase: essential or not essential, that’s the question
Wouter L.W. Hazenbos et al.This article comments on work published by Morisaki et al. (mBio, 2016), which characterized a novel ABC transporter. This transporter apparently compensates for SpsB’s essential function by mediating alternative cleavage of a subset of proteins at a site distinct from the SpsB-cleavage site, leading to SpsB-independent secretion.
