Regional distribution of amyloid-Bri deposition and its association with neurofibrillary degeneration in familial British dementia [PDF]

, 2001
Familial British dementia (FBD), pathologically characterized by cerebral amyloid angiopathy (CAA), amyloid plaques, and neurofibrillary degeneration, is associated with a stop codon mutation in the BRI gene resulting in the production of an ...

Gene Regulation of Biofilm-Associated Functional Amyloids

Pathogens, 2021
Biofilms are bacterial communities encased in a rigid yet dynamic extracellular matrix. The sociobiology of bacterial communities within a biofilm is astonishing, with environmental factors playing a crucial role in determining the switch from planktonic

Amyloid Formation Modulates the Biological Activity of a Bacterial Protein [PDF]

Journal of Biological Chemistry, 2005
The aggregation of proteins into amyloid fibrils is the hallmark feature of a group of late-onset degenerative diseases including Alzheimer, Parkinson, and prion diseases. We report here that microcin E492, a peptide naturally produced by Klebsiella pneumoniae that kills bacteria by forming pores in the cytoplasmic membrane, assembles in vitro into ...

An Imaging and Systems Modeling Approach to Fibril Breakage Enables Prediction of Amyloid Behavior [PDF]

, 2013
Delineating the nanoscale properties and the dynamic assembly and disassembly behaviors of amyloid fibrils is key for technological applications that use the material properties of amyloid fibrils, as well as for developing treatments of amyloid ...

Bacterial amyloid formation: structural insights into curli biogensis. [PDF]

Trends Microbiol, 2015
Curli are functional amyloid fibers assembled by many Gram-negative bacteria as part of an extracellular matrix that encapsulates the bacteria within a biofilm. A multicomponent secretion system ensures the safe transport of the aggregation-prone curli subunits across the periplasm and outer membrane, and coordinates subunit self-assembly into surface ...

Serum amyloid P aids complement-mediated immunity to Streptococcus pneumoniae [PDF]

, 2007
The physiological functions of the acute phase protein serum amyloid P (SAP) component are not well defined, although they are likely to be important, as no natural state of SAP deficiency has been reported.

β-microglobulin amyloid fibril-induced membrane disruption is enhanced by endosomal lipids and acidic pH [PDF]

, 2014
Although the molecular mechanisms underlying the pathology of amyloidoses are not well understood, the interaction between amyloid proteins and cell membranes is thought to play a role in several amyloid diseases. Amyloid fibrils of β-microglobulin (βm),

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.

Mass spectrometric analysis of pilus assembly, amyloid fibril formation, and membrane proteins in their native state [PDF]

, 2012
Structural analysis of proteins and their complexes is crucial to understanding protein function. This thesis demonstrates the application of mass spectrometry (MS) to the study of pilus assembly on Gram-negative bacteria and amyloid formation in ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
