Jorrit M. Enserink

This article comments on work published by Soma et al. (Microbial Cell, 2014), which teased apart the effect of metabolism and growth rate on setting of critical cell size in Saccharomyces cerevisiae.

Only functional localization is faithful localization

Roland Lill1,2,3

This article comments on work published by Peleh et al. (Microbial Cell 2014), which analyzes the localization of Dre2 in Saccharomyces cerevisiae.

This article analyzes the implications of specific metabolites in aging and autophagy with special emphasis on polyamine metabolism.

One cell, one love: a journal for microbial research

Didac Carmona-Gutierrez1, Guido Kroemer2-6 and Frank Madeo1

In this inaugural article of Microbial Cell, we highlight the importance of microbial research in general and the journal's intention to serve as a publishing forum that supports and enfolds the scientific diversity in this area as it provides a unique, high-quality and universally accessible source of information and inspiration.

What’s the role of autophagy in trypanosomes?

Katherine Figarella1 and Néstor L. Uzcátegui1,2

This article comments on Proto et al. (Microbial Cell, 2014), who report first insights into the molecular mechanism of autophagy in African trypanosomes by generating reporter bloodstream form cell lines.

Transceptors as a functional link of transporters and receptors

March 1, 2017

A relative newcomer in environment sensing are the so called transceptors, membrane proteins that possess both solute transport and receptor-like signaling activities. Now, the transceptor concept is further enlarged to include micronutrient sensing via the iron and zinc high-affinity transporters of Saccharomyces cerevisiae.

Using microbes as a key tool to unravel the mechanism of autophagy and the functions of the ATG proteins

December 30, 2016

Microbes 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

December 5, 2016

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.

The curious case of vanishing mitochondria

September 30, 2016

Due to their involvement in the energy metabolism, mitochondria are essential for most eukaryotic cells. Microbial eukaryotes living in low oxygen environments possess reduced forms of mitochondria, namely mitochondrion-related organelles (MROs). Recently, the first microbial eukaryote with neither mitochondrion nor MRO was characterized – Monocercomonoides sp. The discovery of such bona fide amitochondriate eukaryote broadens our knowledge about the diversity and plasticity of eukaryotic cells and provides a substantial contribution to our understanding of eukaryotic cell evolution.

Sexually transmitted infections: old foes on the rise

September 4, 2016

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.

Phosphatidylthreonine: An exclusive phospholipid regulating calcium homeostasis and virulence in a parasitic protist

May 1, 2016

This article comments on work published by Kuchipudi et al. (Microbial Cell, 2016), which describes the role of phohsphatidylthreonine in the regulation of calcium homeostasis and virulence in the protozoan parasite Toxoplasma gondii.

What’s old is new again: yeast mutant screens in the era of pooled segregant analysis by genome sequencing

April 4, 2016

This article comments on work published by Den Abt et al. (Microbial Cell, 2016), which identified genes involved in ethyl acetate formation in a yeast mutant screen based on a new approach combining repeated rounds of chemical mutagenesis and pooled segregant analysis by whole genome sequencing.

Gearing up for survival – HSP-containing granules accumulate in quiescent cells and promote survival
