The small heat shock proteins, especially HspB4 and HspB5 are promising protectants in neurodegenerative diseases

Publication date: May 2018 Source:Neurochemistry International, Volume 115 Author(s): Zhihui Zhu, Georg Reiser Small heat shock proteins (sHsps) are a group of proteins with molecular mass between 12 and 43 kDa. Currently, 11 members of this family have been classified, namely HspB1 to HspB11. HspB1, HspB2, HspB5, HspB6, HspB7, and HspB8, which are expressed in brain have been observed to be related to the pathology of neurodegenerative diseases, including Parkinson's, Alzheimer's, Alexander's disease, multiple sclerosis, and human immunodeficiency virus-associated dementia. Specifically, sHsps interact with misfolding and damaging protein aggregates, like Glial fibrillary acidic protein in AxD, β-amyloid peptides aggregates in Alzheimer's disease, Superoxide dismutase 1 in Amyotrophic lateral sclerosis and cytosine-adenine-guanine/polyglutamine (CAG/PolyQ) in Huntington's disease, Spinocerebellar ataxia type 3, Spinal-bulbar muscular atrophy, to reduce the toxicity or increase the clearance of these protein aggregates. The degree of HspB4 expression in brain is still debated. For neuroprotective mechanisms, sHsps attenuate mitochondrial dysfunctions, reduce accumulation of misfolded proteins, block oxidative/nitrosative stress, and minimize neuronal apoptosis and neuroinflammation, which are molecular mechanisms commonly accepted to mirror the progression and development of neurodegenerative diseases. The increasing incidence of the neurodegenerative diseases enhance...

Psychiatric patients may be at higher risk for memory dysfunction and subsequent Alzheimer due to the negative effects of stress and depression on the brain. We carried out longitudinal within-subject studies in male and female psychiatric patients to identify blood gene expression biomarkers that track short term memory as measured by the retention measure in the Hopkins Verbal Learning Test. These biomarkers were prioritized with a...

Conclusions: The results of this study suggest a difference in perspective between the more optimistic view of persons with dementia and their informal caregivers and the more critical view of physiotherapy experts regarding the most important factors that influence PA participation. In addition, there was a strong focus on the individual characteristics that influence PA behavior that warrant personalized interventions to promote PA in persons with dementia.

Bronchiolitis obliterans (BOS) remains a major cause of death for lung transplant recipients, and mechanisms that drive BOS remain poorly understood. Genetically encoded deficiencies in mitophagy, a specialized autophagy that targets the removal of damaged mitochondria, have been shown to promote Parkinson's disease, but it is unclear if they play a role in other chronic diseases. Recent work has shown that the rs2241880 mutation in the autophagy regulator ATG16L1 leads to protein instability resulting in deficiency of ATG16L1 in monocyte-derived macrophages.

The Alzheimer's disease research community is nowadays ever more strongly considering chronic inflammation in the brain as a vital part of the progression of the condition. In the amyloid cascade hypothesis, a slow aggregation of amyloid-β over decades (for reasons that are debated) causes ever greater inflammatory dysfunction in microglia, the immune cells of the brain responsible for clearing up metabolic waste such as protein aggregates. That inflammation in turn sets the stage for tau aggregation to take place to a significant degree, causing cell death and severe neural dysfunction. Today's open access res...

AbstractBy the discovery of an antibody to aquaporin 4 (AQP4), the clinical and radiological findings of neuromyelitis optica (NMO) such as diffuse cerebral or longitudinally extended spinal cord lesions had been clarified as distinct features from multiple sclerosis (MS). Pathological studies in NMO demonstrated loss of immunoreactivity to AQP4 and glial fibrillary acidic protein but a relative preservation of myelin basic protein, especially at the lesions with perivascular deposition of immunoglobulins and complements, suggesting autoimmune disease against astrocytes. In recent years, the antibody against myelin oligode...
