Biofilm-associated proteins: from the gut biofilms to neurodegeneration

open access: yesGut Microbes
Human microbiota form a biofilm with substantial consequences for health and disease. Numerous studies have indicated that microbial communities produce functional amyloids as part of their biofilm extracellular scaffolds.

Functional characterization of TasA and TapA in the formation of the amyloid fiber in Bacillus subtilis [PDF]

open access: yes, 2017
Introduction Functional amyloids are a very heterogeneous family of amyloid proteins widespread in nature, from humans to bacteria. Unlike their “pathogenic” relatives, implicated in several neurodegenerative diseases, functional amyloids play important

Heterologous prion-forming proteins interact to cross-seed aggregation in Saccharomyces cerevisiae [PDF]

open access: yes, 2017
The early stages of protein misfolding remain incompletely understood, as most mammalian proteinopathies are only detected after irreversible protein aggregates have formed.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Innovative solutions to sticky situations: Antiadhesive strategies for treating bacterial infections [PDF]

open access: yes, 2016
Bacterial adherence to host tissue is an essential process in pathogenesis, necessary for invasion and colonization and often required for the efficient delivery of toxins and other bacterial effectors.

The Amyloid Precursor Protein Controls PIKfyve Function [PDF]

open access: yesPLOS ONE, 2015
While the Amyloid Precursor Protein (APP) plays a central role in Alzheimer's disease, its cellular function still remains largely unclear. It was our goal to establish APP function which will provide insights into APP's implication in Alzheimer's disease.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

open access: yesAdvanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Amyloidosis-history and development, emphasis on insulin and prion amyloids

open access: yesBrain Disorders
Amyloidosis is associated with misfolding of protein (normal functional and cellular) into intractable aggregates, commonly known as amyloid fibrils.

Hsp104 Gives Clients the Individual Attention They Need [PDF]

open access: yes, 2010
Yeast heat shock protein 104 (Hsp104), the only known eukaryotic disaggregase, remodels both disordered protein aggregates and cross-β sheet amyloids. To handle this diverse clientele, DeSantis et al.

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate
