From molecule to molecule and cell to cell: Prion-like mechanisms in amyotrophic lateral sclerosis
Neurobiology of Disease, 2015 Prions, self-proliferating infectious agents consisting of misfolded protein, are most often associated with aggressive neurodegenerative diseases in animals and humans.

A Small‐Molecule DEPTAC Rescues Cognitive Deficits by Targeted Dephosphorylation of Pathological Tau
Advanced Science, EarlyView.TP2 is a fully synthetic small‐molecule dephosphorylation‐targeting chimera that recruits endogenous PP2A‐Bα to Tau, enabling targeted removal of pathological phosphate modifications. In two tauopathy mouse models, systemic TP2 reduces Tau pathology, preserves neuronal and synaptic integrity, improves neuroimmune homeostasis, and rescues cognition ...

Angewandte Chemie, EarlyView.This review highlights an emerging anticancer approach integrating platinum agents into photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) systems, further augmented by cancer cell membrane‐ and organelle‐targeting. By directing photoactivated platinum complexes from nontargeted distribution to cancer cells or defined subcellular sites ...

Brazilian Journal of Medical and Biological Research, 2005 In the last few years, hydrostatic pressure has been extensively used in the study of both protein folding and misfolding/aggregation. Compared to other chemical or physical denaturing agents, a unique feature of pressure is its ability to induce subtle ...

Advanced Science, EarlyView.An intelligent engineered probiotic platform is developed for the precision management of inflammatory bowel disease. By integrating surface‐displayed adhesins with an inflammation‐responsive CAT‐SOD‐GPx tripartite fusion system and mucosal repair factors, this programmable system achieves prolonged intestinal retention and multi‐pronged therapy.

Characterisation of the oxidoreductase Erol-Lß and the misfolding of the secretory pathway substrate HLA-B27 [PDF]
, 2007 The endoplasmic reticulum (ER) is the site of oxidative folding for proteins entering the secretory pathway. Here, nascent polypeptides acquire disulfide bonds, which confer both stability and functionality on secretory and ER-resident proteins.

Nanoimaging for Protein Misfolding and Related Diseases
, 2006 Misfolding and aggregation of proteins is a common thread linking a number of important human health problems. The misfolded and aggregated proteins are inducers of cellular stress and activators of immunity in neurodegenerative diseases.

pH‐Driven Two‐Stage Conformational Switching Activates an Acid‐Responsive Chaperone
Angewandte Chemie, EarlyView.AchC is an ATP‐independent, pH‐responsive chaperone. AchC functions as a molecular switch, sensing pH changes and undergoing a two‐stage conformational transition: C‐terminal extension (colored in yellow) loosening at mild pH 4.0–5.5 and monomerization at strong acidic pH 3.0.

Frontiers in Molecular Neuroscience, 2018 Protein quality control (PQC) is critical to maintain a functioning proteome. Misfolded or toxic proteins are either refolded or degraded by a system of temporal quality control and can also be sequestered into aggregates or inclusions by a system of ...

Huntingtin Aggregate‐Responsive Autophagy Gene Circuit Mitigates Disease Pathology in R6/2 Mice
Advanced Science, EarlyView.CD98‐mediated receptor‐mediated transcytosis enables LIP‐CD98 nanocarriers to cross the blood–brain barrier and deliver ARAA to neurons. mHTT aggregates activate the 11G–NarX sensor, initiating Auto‐P and Trans‐P signaling through the VP48–NarL relay.
