Julia Graf1, Leonard Fresenborg1,2, Hans-Michael Seitz2,3, Rafael Pernil1 and Enrico Schleiff1,2,4,5
Metal homeostasis is central to all forms of life, as metals are essential micronutrients with toxic effects at elevated levels. Our results provide novel information on the uptake of cobalamin and the regulation of the cellular cobalt content in cyanobacteria.
Predictable regulation of survival by intratumoral microbe-immune crosstalk in patients with lung adenocarcinoma
Shuo Shi1, Yuwen Chu2,3, Haiyan Liu4,5, Lan Yu6,7,8, Dejun Sun8,9, Jialiang Yang2,3,5, Geng Tian2,3, Lei Ji2,3, Cong Zhang10 and Xinxin Lu11
Intratumoral microbiota can regulate the tumor immune microenvironment (TIME) and mediate tumor prognosis by promoting inflammatory response or inhibiting anti-tumor effects. Our study demonstrated that intratumoral microbiota-immune crosstalk was strongly associated with prognosis in LUAD patients, which would provide new targets for the development of precise therapeutic strategies.
Two TonB-dependent outer membrane transporters involved in heme uptake in Anabaena sp. PCC 7120
Julia Graf1, Martin Schöpperle1,2, Rafael Pernil1 and Enrico Schleiff1,3,4
Low availability of micronutrients such as iron has enforced the evolution of uptake systems in all kingdoms of life. In our study, we conclude that heme transport might not be restricted to Anabaena, but at the same time is not specific to a cyanobacterial order and thus might be related to the habitat of origin, a notion which needs to be challenged in the future.

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.
