Macrocycles are an attractive class of molecules due to their good binding properties and yet rather small size that allows, in many cases, crossing membranes to reach intracellular targets. In comparison to classical small molecule drugs, macrocycles are ...

The brain pathology of Alzheimer’s disease (AD) is characterized by the misfolding and aggregation of both the amyloid beta (Aβ) peptide and hyperphosphorylated forms of the tau protein. Initial Aβ deposition is considered to trigger a sequence of deleteri ...

Here we provide a personal account of innovation and design principles underpinning a method to interrogate precision electrophile signaling that has come to be known as "REX technologies". This Account is framed in the context of trying to improve methods ...

Several lines of evidence from neuropathological studies, human genetics, in vitro aggregation studies and cellular and animal models support the hypothesis that aSyn plays a central role in the formation of Lewy pathologies. These are cytoplasmic proteina ...

Alteration to endoplasmic reticulum (ER) proteostasis is observed in a variety of neurodegenerative diseases associated with abnormal protein aggregation. Activation of the unfolded protein response (UPR) enables an adaptive reaction to recover ER proteost ...

The molecular steps that lead to the disaggregation of amyloid fibrils are shown to involve the synergistic action of HSP70 and its co-chaperones DNAJB1 and HSP110. ...

Increasing evidence suggests that crosstalk between α-synuclein pathology formation and mitochondrial dysfunction plays a central role in the pathogenesis of Parkinson’s disease and related synucleinopathies. While mitochondrial dysfunction is a well-studi ...

Loss of mitochondrial function and proteostasis typify aging and age-associated degenerative disorders such as Alzheimer's disease and muscle aging. To date, no cure or preventive measure is available to manage these conditions. Alterations of cellular pro ...

Alzheimer's disease (AD) is the most common form of dementia in the elderly. AD is characterized by the deposition of two aggregated proteins: Amyloid beta (Aß) and hyperphosphorylated tau. Accumulations of these proteins are thought to be the signature ...

Lewy bodies (LBs) are α-synuclein (α-syn)-rich intracellular inclusions that are an important pathological hallmark of Parkinson disease and several other neurodegenerative diseases. Increasing evidence suggests that the aggregation of α-syn has a central ...

Accumulation and aggregation of misfolded alpha-synuclein is believed to be a cause of Parkinson's disease (PD). Phosphorylation of alpha-synuclein at S129 is known to be associated with the pathological misfolding process, but efforts to investigate the r ...

alpha-Synuclein aggregation at the synapse is an early event in Parkinson's disease and is associated with impaired striatal synaptic function and dopaminergic neuronal death. The cysteine string protein (CSP alpha) and alpha-synuclein have partially overl ...

Autophagy is a highly conserved process by which long-lived macromolecules, protein aggregates and dysfunctional/damaged organelles are delivered to lysosomes for degradation. Autophagy plays a crucial role in regulating protein quality control and cell ho ...

A compelling link is emerging between the posttranslational modification O-GlcNAc and protein aggregation. A prime example is alpha-synuclein, which forms toxic aggregates that are associated with neurodegeneration in Parkinson's and related diseases. alph ...

Huntington’s disease is a neurodegenerative dis- order caused by the expansion of a polyglutamine repeat (>36Q) in the N-terminal domain of the huntingtin protein (Htt), which renders the protein or fragments thereof more prone to aggregate and form inclus ...

Tauopathies are neurodegenerative diseases whose common pathological feature is the intraneuronal accumulation of tau aggregates. Tau protein has various roles in the neuron, among which stabilization of microtubules (MT), regulation of synaptic activity o ...

Directed, intentional imagination is pivotal for self-regulation in the form of escapism and therapies for a wide variety of mental health conditions, such anxiety and stress disorders, as well as phobias. Clinical application in particular benefits from i ...
