Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

A Covert Operation by a Plant Pathogen [PDF]

open access: yesCell Host & Microbe, 2016
Phytopathogens have mastered the ability to evade plant innate immunity. In this issue of Cell Host & Microbe, Zhou and colleagues (Li et al., 2016) uncover a strategy whereby a bacterial pathogen disables the plant immune system with such precision as to avoid triggering alarms that could potentially reveal its presence.

External pH: An Environmental Signal That Helps to Rationalize pel Gene Duplication in Erwinia chrysanthemi

open access: yesMolecular Plant-Microbe Interactions, 2000
The phytopathogenic bacterium Erwinia chrysanthemi produces five major pectate lyases that are key virulence factors in soft-rot disease development. Using transcriptional fusions, we studied the regulation of pelA, pelD, and pelE gene expression as a ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Investigating the Pea Virome in Germany—Old Friends and New Players in the Field(s)

open access: yesFrontiers in Microbiology, 2020
Peas are an important legume for human and animal consumption and are also being used as green manure or intermediate crops to sustain and improve soil condition. Pea production faces constraints from fungal, bacterial, and viral diseases.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Interlaboratory Validation of High-Throughput Sequencing for the Detection of Viruses and Viroids in Apple, Grapevine, and Stone Fruits

open access: yesPhytoFrontiers
High-throughput sequencing (HTS) has been demonstrated to be a paradigm shift for post-entry quarantine programs by increasing their ability to detect unknown plant viruses that have remained undetected by conventional diagnostic tools.

Machine learning identifies straightforward early warning rules for human Puumala hantavirus outbreaks

open access: yesScientific Reports, 2023
Human Puumala virus (PUUV) infections in Germany fluctuate multi-annually, following fluctuations of the bank vole population size. We applied a transformation to the annual incidence values and established a heuristic method to develop a straightforward

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Genome-Informed Real-Time Polymerase Chain Reaction for Detection of Erwinia pyrifoliae, the Causal Agent of Asian Pear Blight

open access: yesPhytoFrontiers
Erwinia pyrifoliae causes blight symptoms on pears (Pyrus spp.), apple (Malus spp.), and strawberry (Fragaria × ananassa), with up to 40% losses in strawberry observed during a 2013 outbreak in the Netherlands.
