Uncovering a previously unknown function of polyphosphate in polyadenylated RNA‐induced amyloidogenesis of Hfq

The FEBS Journal, EarlyView.
Polyphosphate interaction with Hfq and RNA drives phase separation and amyloid self‐assembly, uncovering a previously unrecognized role for polyP in bacterial stress responses. Our findings reveal new insights into the molecular mechanisms of RNA‐mediated phase separation, highlighting the role of polyP as a key modulator of this process. Polyphosphate

Structural biology of bacterial functional amyloid formation

, 2015
Amyloids are proteinaceous aggregates best known for their role in degenerative diseases involving protein misfolding. Research into amyloid has intensified in recent times due to its prominence in many debilitating human diseases and limited understanding of the causes.

ADAM17 and its proteolytic targets in disease pathogenesis

The FEBS Journal, EarlyView.
ADAM17 as a multifunctional sheddase with contrasting roles across inflammatory, metabolic, cardiovascular, and neoplastic diseases. Through regulated activation by iRhom, iTAP/FRMD8, and tetraspanins, ADAM17 cleaves diverse membrane ligands and receptors, thereby promoting inflammation, fibrosis, obesity, insulin resistance, and tumor progression ...

Hsp70 diversification and repurposing across the tree of life: Lessons from the evolutionary and mechanistic trajectory of the Hsp70–Hsp110 chaperone system

The FEBS Journal, EarlyView.
Evolutionary and mechanistic divergence in the Hsp70–Hsp110 chaperone system. Prokaryotic Hsp70s probably diversified into multiple orthologues that cooperated with co‐chaperones such as JDPs and NEF, forming increasingly complex proteostasis networks.

Water, water, every where—the advent of hydrated pili structure

The FEBS Journal, EarlyView.
Protein structure is defined by its surrounding water. Naturally, this is also true for the gigantic protein filaments that pathogenic bacteria use to attach to and colonize their host cells. Structures of these filaments for which water can be identified with high confidence have stayed elusive for the longest time.

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

The FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Porphyromonas gingivalis Outer Membrane Vesicles‐Associated DNA Triggers Inflammation by Inducing IL‐6 in Astrocytes

Molecular Oral Microbiology, EarlyView.
Pg releases OMVs which contain Pg genomic DNA. The Pg OMVs‐associated DNA is incorporated into astrocytes via endocytosis and increases IL‐6 mRNA expression via TLR9. These effects of Pg OMVs may induce neuroinflammation, which could contribute to the onset and progression of AD in periodontal disease.
