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 ...

Abstract Bee venom is a very complex mixture of natural products extracted from honey bee which contains various pharmaceutical properties such as peptides, enzymes, biologically active amines and nonpeptide components. The use of bee venom into the specific points is so called bee venom therapy, which is widely used as a complementary and alternative therapy for 3000 years. A growing number of evidence has demonstrated the anti-inflammation, the anti-apoptosis, the anti-fibrosis and the anti-arthrosclerosis effects of bee venom therapy. With these pharmaceutical characteristics, bee venom therapy has also been us...

Abstract Alzheimer's disease, Parkinson's, Huntington's, amyotrophic lateral sclerosis (ALS) and prion disorders are devastating neurodegenerative diseases of increasing prevalence in aging populations. Although clinically different, they share similar molecular features: the accumulation of one or two proteins in abnormal conformations inside or outside neurons. Enhancing protein quality control systems could be a useful strategy to neutralize the abnormal proteins causing neurodegenerative diseases. This review emphasizes the subcellular location of protein deposits in neurodegenerative diseases and the need to ...

Abstract Traditionally neurological diseases have been classified, on the basis of their pathogenesis, into vascular, degenerative, inflammatory and traumatic diseases. Examples of the main inflammatory neurological diseases include multiple sclerosis, which is characterized by an immune-mediated immune response against myelin proteins, and meningoencephalitis, where the inflammatory response is triggered by infectious agents. However, recent evidence suggests a potential role of inflammatory mechanisms also in neurological conditions not usually categorized as inflammatory, such as Alzheimer's disease, Parkinson'...

PGC-1α sparks the fire of neuroprotection against neurodegenerative disorders. Ageing Res Rev. 2018 Mar 23;: Authors: Lv J, Jiang S, Yang Z, Hu W, Wang Z, Li T, Yang Y Abstract Recently, growing evidence has demonstrated that peroxisome proliferator activated receptor γ (PPARγ) coactivator-1α (PGC-1α) is a superior transcriptional regulator that acts via controlling the expression of anti-oxidant enzymes and uncoupling proteins and inducing mitochondrial biogenesis, which plays a beneficial part in the central nervous system (CNS). Given the significance of PGC-1α, ...

CONCLUSION: Due to the costs associated with experimentation and current ethical law, performing experiments directly on living organisms has become much more difficult. In this scenario, in silico techniques have been successful and have become powerful tools in the search to cure disease. Researchers use the Computer Aided Drug Design pipeline which: 1) generates 3-dimensional structures of target proteins through homology modeling 2) achieves stabilization through molecular dynamics simulation, and 3) exploits molecular docking through large compound libraries. Next generation sequencing is continually producing enormou...

Authors: Tae WS, Ham BJ, Pyun SB, Kang SH, Kim BJ Abstract Diffusion-tensor imaging (DTI) is a noninvasive medical imaging tool used to investigate the structure of white matter. The signal contrast in DTI is generated by differences in the Brownian motion of the water molecules in brain tissue. Postprocessed DTI scalars can be used to evaluate changes in the brain tissue caused by disease, disease progression, and treatment responses, which has led to an enormous amount of interest in DTI in clinical research. This review article provides insights into DTI scalars and the biological background of DTI as a relative...
