A comparative approach to decipher intestinal animal-microbe associations

Keisuke Nakashima1

In this article, the authors comment on the study "Chitin-based barrier immunity and its loss predated mucus-colonization by indigenous gut microbiota" by Nakashima et al. (Nat Commun, 2018) that used comparative analyses of chordates to investigate the development of animal-microbe associations, suggesting that microbial colonization of the mucus layer over mammalian gastrointestinal epithelium was established upon the loss of ancestral chitin-based barrier immunity, providing insights into the establishment of these associations in an evolutionary context.

An unexpected benefit from E. coli: how enterobactin benefits host health

Aileen K. Sewell1,2, Min Han1,2 and Bin Qi1,2

In this article, the authors comment on the study "Microbial Siderophore Enterobactin Promotes Mitochondrial Iron Uptake and Development of the Host via Interaction with ATP Synthase" by Qi et al. (Cell, 2018) that uncovered a surprising role for the Escherichia coli-produced siderophore enterobactin (Ent) in facilitating iron uptake by the host, marking a major shift in the understanding of its function and indicating potential new benefits from commensal bacteria in aiding the host's iron homeostasis.

A Cinderella story: how the vacuolar proteases Pep4 and Prb1 do more than cleaning up the cell’s mass degradation processes

Winnie Kerstens1,2 and Patrick Van Dijck1,2

This review summarizes the expanded roles of the Saccharomyces cerevisiae vacuolar proteases Pep4 and Prb1 in non-vacuolar activities outside of autophagy, such as programmed cell death, protection from harmful protein forms, and gene expression regulation. The potential implications of these findings for fungal biology and drug target discovery, including insights for mammalian cell studies, are highlighted, emphasizing the need for a deeper understanding of these molecular processes.

The biosynthesis of pyoverdines

Michael T. Ringel1 and Thomas Brüser1

This review provides an overview of pyoverdine biosynthesis, emphasizing the distinctive fluorophore shared by various pyoverdines derived from ferribactins and the role of periplasmic processes in the maturation and modification of these siderophores, critical for the growth and colonization of hosts by fluorescent pseudomonads.

Toxin release mediated by the novel autolysin Cwp19 in Clostridium difficile

Imane El Meouche1 and Johann Peltier2,3

In this article, the authors comment on the study "Cwp19 is a novel lytic transglycosylase involved in stationary-phase autolysis resulting in toxin release in Clostridium difficile" by Wydau-Dematteis (MBio, 2018) that characterizes a novel peptidoglycan hydrolase, Cwp19, in Clostridioides difficile, highlighting its glucose-dependent mediation of toxins secretion and suggesting a potential role in the pathogenesis of this bacterium, contributing to the understanding of these enzymes in C. difficile and their implication in pathogenicity.

Escherichia coli hijack Caspr1 receptor to invade cerebral vascular and neuronal hosts

Wei-Dong Zhao1, Dong-Xin Liu1, Yu-Hua Chen1

In this article, the authors comment on the study "Caspr1 is a host receptor for meningitis-causing Escherichia coli" by Zhao et al. (Nat Commun, 2ß18) that identified Caspr1 as a key host receptor for E. coli virulence factor IbeA, facilitating E. coli penetration through the blood-brain barrier (BBB). The research demonstrated that targeting the interaction between IbeA and Caspr1 could potentially neutralize E. coli virulence and prevented meningitis, shedding light on the mechanisms of bacterial invasion into brain endothelial cells and hippocampal neurons.
