Proteostasis of organelles in aging and disease
The FEBS Journal, EarlyView.Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

An update on the landscape of collagen bioactive fragments
The FEBS Journal, EarlyView.The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

The FEBS Journal, EarlyView.Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

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 ...

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.

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.

Proteolytic remodelling of the extracellular matrix by pericytes
The FEBS Journal, EarlyView.Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.

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.
