Origin of life: β‐sheet amyloid conformers as the primordial functional polymers on the early Earth and their role in the emergence of complex dynamic networks

open access: yesFEBS Letters, EarlyView.
The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation

open access: yesFEBS Letters, EarlyView.
The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.
