pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Reference Pricing Versus Co-Payment in the Pharmaceutical Industry: Firm's Pricing Strategies [PDF]

Within a horizontally differentiation model and allowing for heterogeneous qualities, we analyze the effects of reference pricing reimbursement on firms’ pricing strategies. With this analysis we find inherent incentives for firms’ pricing behaviour, and

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

State of knowledge of earthworm communities in German soils as a basis for biological soil quality

Soil Organisms
Within a project aiming to improve the preconditions for the protection of the habitat function of soils in Germany, the database Bo-Info was established, in which soil-biological data from permanent soil monitoring sites of several German states as ...

French National Protocol for Diagnosis and Care of Calpainopathy (LGMD R1/LGMD D4): consensus guidelines for clinical practice

Orphanet Journal of Rare Diseases
Background Calpainopathies, including limb-girdle muscular dystrophy recessive type 1 (LGMD R1) and the rare dominant type 4 (LGMD D4), are genetic neuromuscular disorders caused by pathogenic variants in the CAPN3 gene, which encodes calpain-3, a muscle-

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
