Patterns of protein synthesis in the budding yeast cell cycle: variable or constant?
No et al.Proteins are the principal macromolecular constituent of proliferating cells, and protein synthesis is viewed as a primary metric of cell growth. While there are celebrated examples of proteins whose levels are periodic in the cell cycle (e.g., cyclins), the concentration of most proteins was not thought to change in the cell cycle, but some recent results challenge this notion. The ‘bulk’ protein is the focus of this article, specifically the rate of its synthesis, in the budding yeast Saccharomyces cerevisiae.

Flagellated bacterial porter for in situ tumor vaccine
Xu et al.Cancer immunotherapy, which use the own immune system to attack tumors, are increasingly popular treatments. But, due to the tumor immunosuppressive microenvironment, the antigen presentation in the tumor is limited. Recently, a growing number of people use bacteria to stimulate the body’s immunity for tumor treatment due to bacteria themselves have a variety of elements that activate Toll-like receptors. Here, we discuss the use of motility of flagellate bacteria to transport antigens to the tumor periphery to activate peritumoral dendritic cells to enhance the effect of in situ tumor vaccines.
The rise of Candida auris: from unique traits to co-infection potential
Egger et al.Candida auris is a multidrug resistant (MDR) fungal pathogen with a crude mortality rate of 30-60%. First identified in 2009, C. auris has been rapidly rising to become a global risk in clinical settings and was declared an urgent health threat by the Centers for Disease Control and Prevention (CDC). A concerted global action is thus needed to successfully tackle the challenges created by this emerging fungal pathogen. In this brief article, we underline the importance of unique virulence traits, including its easy transformation, its persistence outside the host and its resilience against multiple cellular stresses, as well as of environmental factors that have mainly contributed to the rise of this superbug.
A hundred spotlights on microbiology: how microorganisms shape our lives
Carmona-Gutierrez et al.Viral, bacterial, fungal and protozoal biology is of cardinal importance for the evolutionary history of life, ecology, biotechnology and infectious diseases. Various microbiological model systems have fundamentally contributed to the understanding of molecular and cellular processes, including the cell cycle, cell death, mitochondrial biogenesis, vesicular fusion and autophagy, among many others. Microbial interactions within the environment have profound effects on many fields of biology, from ecological diversity to the highly complex and multifaceted impact of the microbiome on human health. Also, biotechnological innovation and corresponding industrial operations strongly depend on microbial engineering. With this wide range of impact in mind, the peer-reviewed (…)
Yeast goes viral: probing SARS-CoV-2 biology using S. cerevisiae
Ho et al.The budding yeast Saccharomyces cerevisiae has long been an outstanding platform for understanding the biology of eukaryotic cells. Robust genetics, cell biology, molecular biology, and biochemistry complement deep and detailed genome annotation, a multitude of genome-scale strain collections for functional genomics, and substantial gene conservation with Metazoa to comprise a powerful model for modern biological research. Recently, the yeast model has demonstrated its utility in a perhaps unexpected area, that of eukaryotic virology. Here we discuss three innovative applications of the yeast model system to reveal functions and investigate variants of proteins encoded by the SARS-CoV-2 virus.

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.Check Article Types and Manuscript Preparation guidelines. Submit online via Scholastica.
