Bacterial inclusion bodies are industrially exploitable amyloids

, 2019
Understanding the structure, functionalities and biology of functional amyloids is an issue of emerging interest. Inclusion bodies, namely protein clusters formed in recombinant bacteria during protein production processes, have emerged as unanticipated, highly tunable models for the scrutiny of the physiology and architecture of functional amyloids ...

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

The FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

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 ...

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

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 ...

Immune involvement in neuropsychiatric disorders: Insights from single‐cell transcriptomic studies

Psychiatry and Clinical Neurosciences, EarlyView.
Neuropsychiatric disorders pose profound challenges to both research and treatment, largely due to their clinical heterogeneity and the limited understanding of their underlying biological mechanisms. While bulk RNA sequencing (bulk RNA‐seq) has been widely used to study gene expression, it cannot resolve cell‐type‐specific signals or detect rare ...
