Regulation of extracellular vesicles for protein secretion in Aspergillus nidulans
This study reveals that Aspergillus nidulans boosts extracellular vesicle production when ER-trafficked enzymes are induced, uncovering how fungi remodel their secretome through vesicle-mediated secretion to adapt to changing environments and biofilm formation.
Transcriptomic response to different heme sources in Trypanosoma cruzi epimastigotes
This study uncovers how the Chagas disease parasite adapts to changes in heme, an essential molecule for its survival, providing transcriptional clues to heme metabolism and identifying a previously unreported heme-binding protein in T. cruzi.
Luminal acetylation of microtubules is not essential for Plasmodium berghei and Toxoplasma gondii survival
Acetylation of α-tubulin at lysine 40 is not essential for cytoskeletal stability in Plasmodium berghei or Toxoplasma gondii, suggesting redundancy and plasticity in microtubule regulation in these parasites.
The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in Saccharomyces cerevisiae
S. cerevisiae is a model to study human GPCRs. N-8-Iper, active against glioblastoma via M2 receptor, causes mitochondrial damage in yeast by binding Ste2, highlighting evolutionary conservation of GPCRs.

Ji-In Ryua, Juhye Junga, and Jeong-Yoon Kim
This study establishes Sir2 as a previously unrecognized regulator of selective autophagy during the stationary phase and highlight how cells dynamically control organelle degradation.
Protein oxidation in the intermembrane space of mitochondria is substrate-specific rather than general
Valentina Peleh1, Jan Riemer2, Andrew Dancis3 and Johannes M. Herrmann1
In this work, the authors suggest that in Saccharomyces cerevisiae, the Mia40-dependent oxidation of proteins in the intermembrane space only takes place in specific proteins and presumably relies on the presence of Mia40-binding sites.
Deletion of AIF1 but not of YCA1/MCA1 protects Saccharomyces cerevisiae and Candida albicans cells from caspofungin-induced programmed cell death
Christopher Chin1,2,#, Faith Donaghey1,#, Katherine Helming1,3,#, Morgan McCarthy1,#, Stephen Rogers1, and Nicanor Austriaco1
This work suggests that deleting AIF1 but not YCA1/MCA1 protects S. cerevisiae and Candida albicans from caspofungin-induced cell death. This is not only the first time that AIF1 has been specifically tied to cell death in Candida but also the first time that caspofungin resistance has been linked to the cell death machinery in yeast.
Reduced TORC1 signaling abolishes mitochondrial dysfunctions and shortened chronological lifespan of Isc1p-deficient cells
Vitor Teixeira1,2, Tânia C. Medeiros1, Rita Vilaça1,2, Pedro Moradas-Ferreira1,2, and Vítor Costa1,2
Overall, this article shows that the TORC1-Sch9p axis is deregulated in Isc1p-deficient Saccharomyces cerevisiae cells, contributing to mitochondrial dysfunction, enhanced oxidative stress sensitivity and premature aging of isc1Δ cells.
Early manifestations of replicative aging in the yeast Saccharomyces cerevisiae.
Maksim I. Sorokin1,3, Dmitry A. Knorre2,3, and Fedor F. Severin2,3
The data preseted herein suggest that retrograde signaling starts to malfunction in relatively young cells, leading to accumulation of heterogeneous mitochondria within one cell. The latter may further contribute to a decline in stress resistances.

Autophagy: machinery and regulation
Zhangyuan Yin, Clarence Pascual and Daniel J. Klionsky
Macroautophagy/autophagy is an evolutionarily conserved cellular degradation process that targets cytoplasmic materials including cytosol, macromolecules and unwanted organelles. The discovery and analysis of autophagy-related (Atg) proteins have unveiled much of the machinery of autophagosome formation. In this review, we briefly summarize the physiological roles, molecular mechanism, regulatory network, and pathophysiological roles of autophagy.

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.
