Role of hydrogen sulfide and polysulfides in neurological diseases: focus on protein S-Persulfidation.

Role of hydrogen sulfide and polysulfides in neurological diseases: focus on protein S-Persulfidation. Curr Neuropharmacol. 2020 Sep 05;: Authors: Sun HJ, Wu ZY, Nie XW, Bian JS Abstract Hydrogen sulfide (H2S) and hydrogen polysulfides are recognized as important signaling molecules that are generated physiologically in the body, including the central nervous system (CNS). Studies have shown that these two molecules are involved in cytoprotection against oxidative stress and inflammatory response. In the brain system, H2S and polysulfides exert multiple functions in both health and diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), memory decline, and glioma. Mechanistically, S-Persulfidation (also known as S-sulfuration or S-sulfhydration) of target proteins is believed to be a fundamental mechanism that underlies H2S-regulated signaling pathways. Cysteine S-Persulfidation is an important paradigm of post-translational protein modification in the process of H2S signaling. This model is established as a critical redox mechanism to regulate numerous biological functions, especially in H2S-mediated neuroprotection and neurogenesis. Although the current research of S-Persulfidation is still in its infancy, accumulative evidence suggests that protein S-Persulfidation may share similar characteristics with protein S-nitrosylation. In this review, we will provide a comprehensive insight into the S-Persulfidation ...

Abstract Glioblastoma multiforme (GBM) is a devastating disease without cure. It is also the most common primary brain tumor in adults. Although aggressive surgical resection is standard of care, these operations are limited by tumor infiltration of critical cortical and subcortical regions. A better understanding of how the brain can recover and reorganize function in response to GBM would provide valuable clinical data. This ability, termed neuroplasticity, is not well understood in the adult human brain. A better understanding of neuroplasticity in GBM could allow for improved extent of resection, even in areas...

Aβ-Induced Repressor Element 1-Silencing Transcription Factor (REST) Gene Delivery Suppresses Activation of Microglia-Like BV-2 Cells. Neural Plast. 2020;2020:8888871 Authors: Yu T, Quan H, Xu Y, Dou Y, Wang F, Lin Y, Qi X, Zhao Y, Liu X Abstract Compelling evidence from basic molecular biology has demonstrated the crucial role of microglia in the pathogenesis of Alzheimer's disease (AD). Microglia were believed to play a dual role in both promoting and inhibiting Alzheimer's disease progression. It is of great significance to regulate the function of microglia and make them develop in a favorabl...

In this study, we used UPLC-MS to generate a chromatographic fingerprinting of BTF and identified five possible active ingredients, including stilbene glycoside; epimedin A1, B, and C; and icariin. We also showed that oral administration of BTF reversed the cognitive defects in an Aβ 1-42 fibril-infused rat model of AD, protected synaptic ultrastructure in the CA1 region, and restored the expression of BDNF, synaptotagmin (Syt), and PSD95. These effects likely occurred through the BDNF-activated receptor tyrosine kinase B (TrkB)/Akt/CREB signaling pathway. Furthermore, BTF exhibited no short-term or chronic toxicity i...

Abstract As the global population ages, the incidence of neurodegenerative diseases has risen. Furthermore, it has been suggested that depression, especially in elderly people, may also be an indication of latent neurodegeneration. Stroke, Alzheimer's disease (AD), and Parkinson's disease (PD) are usually accompanied by depression. The urgent challenge is further enforced by psychiatric comorbid conditions, particularly the feeling of despair in these patients. Fortunately, as our understanding of the neurobiological substrates of maladies affecting the central nervous system (CNS) has increased, more therapeutic ...
