The metabolites of lactic acid bacteria: classification, biosynthesis and modulation of gut microbiota

The metabolites of lactic acid bacteria: classification, biosynthesis and modulation of gut microbiota

Huang Tang1,2, Wanqiu Huang1,2 and Yu-Feng Yao1,2,3,4,5

Lactic acid bacteria (LAB) are ubiquitous microorganisms that can colonize the intestine and participate in the physiological metabolism of the host. In this review, we summarize the metabolites of LAB and their influence on the intestine as well as the underlying regulatory mechanisms and their impact on human health.

The role of invariant surface glycoprotein 75 in xenobiotic acquisition by African trypanosomes

Alexandr Makarov1, Jakub Began2,†, Ileana Corvo Mautone1,3, Erika Pinto1, Liam Ferguson1, Martin Zoltner1,4, Sebastian Zoll2 and Mark C. Field1,5

By CRISPR/Cas9 knockout and biophysical analysis, we show here that the invariant surface glycoprotein 75 directly binds the the century-old drug suramin and mediates uptake of additional naphthol-related compounds, making this glycoprotein a conduit for entry of at least one structural class of trypanocidal compounds.

The first taxonomic and functional characterization of human CAVD-associated microbiota

Lavinia Curini1,#, Brunilda Alushi2,#, Mary Roxana Christopher3, Simone Baldi1, Leandro Di Gloria4, Pierluigi Stefano5, Anna Laganà5, Luisa Iannone5, Herko Grubitzsch6, Ulf Landmesser7, Matteo Ramazzotti4, Elena Niccolai1,§, Alexander Lauten2,§ and Amedeo Amedei1,8,§

Calcific aortic valve disease (CAVD) is the most common heart valve disorder, defined by a remodeling multistep process. In this study, we aimed to investigate and characterize the presence of valvular microbiota and the associated immune response in human CAV samples originating from two European populations.

Cellular cholesterol licenses <i>Legionella pneumophila</i> intracellular replication in macrophages

Cellular cholesterol licenses Legionella pneumophila intracellular replication in macrophages

Edna Ondari1,#, Ashley Wilkins1,#, Brian Latimer3, Ana-Maria Dragoi2,3 and Stanimir S. Ivanov1

Host membranes are inherently critical for niche homeostasis of vacuolar pathogens such as Legionella. One membrane component that is often subverted by vacuolar bacteria is cholesterol. We provide experimental evidence that cellular cholesterol promotes L. pneumophila replication within a membrane bound organelle in infected macrophages.

Phospholipases A and Lysophospholipases in protozoan parasites

Phospholipases A and Lysophospholipases in protozoan parasites

Perrine Hervé1, Sarah Monic1, Frédéric Bringaud1 and Loïc Rivière1

In this review, we summarize the literature on phospholipases and lysophospholipases in several protozoan parasites of medical relevance, and discuss the growing interest for them as potential drug and vaccine targets.

Biofilm tolerance, resistance and infections increasing threat of public health

Biofilm tolerance, resistance and infections increasing threat of public health

Shanshan Yang1,3, Xinfei Li1,2, Weihe Cang1,2, Delun Mu1,3, Shuaiqi Ji1,3, Yuejia An1, Rina Wu1,2,3 and Junrui Wu1,2,3

The review explores the role of biofilms in the development of bacterial resistance mechanisms and proposed therapeutic intervention strategies for biofilm related diseases.

Infinity war: <i>Trichomonas vaginalis</i> and interactions with host immune response

Infinity war: Trichomonas vaginalis and interactions with host immune response

Giulia Bongiorni Galego1 and Tiana Tasca1

Trichomonas vaginalis is the pathological agent of human trichomoniasis with an incidence of 156 million cases worldwide. This review highlights parasite strategies to activate and stimulate or evade variated and complex immunological mechanisms related to the symptoms and clinical complications observed here.

Ribose 5-phosphate: the key metabolite bridging the metabolisms of nucleotides and amino acids during stringent response in Escherichia coli?

Paulina Katarzyna Grucela1, Tobias Fuhrer2, Uwe Sauer2, Yanjie Chao3 and Yong Everett Zhang1

Here we propose the metabolite ribose 5’-phosphate as the key link between nucleotide and amino acid metabolisms and a working model integrating both the transcriptional and metabolic effects of (p)ppGpp on E. coli physiological adaptation during the stringent response.
