Oxidative stress plays an important role in the pathological processes of a variety of neurodegenerative diseases. The neuroprotective effects of 3,5-diCQA and 3,4-diCQA, two caffeoylquinic acid derivatives present in Dipsacus asper, on hydrogen peroxide (H2O2)-induced neuronal cell damage were evaluated in this study.SH-SY5Y cells treated with H2O2 exhibited a decrease in survival and intracellular glutathione and also an increase in the caspase-3 activity. However, pretreatment of cells with 3,5-diCQA attenuated the neuronal death and caspase-3 activation induced by H2O2. In addition, 3,5-diCQA restored H2O2-induced depletion of intracellular glutathione. 3,5-diCQA showed significant protective effects although it could not completely suppress H2O2-induced cell injury to control levels. The data suggest that 3,5-diCQA might be a potential therapeutic agent for treating or preventing neurodegenerative diseases implicated with oxidative stress.

Background: Ischemic stroke is a prevalent and life-threatening cerebrovascular disease that is challenging to treat and associated with a poor prognosis. Astragaloside IV (AS-IV), a primary bioactive component of Astragali radix, has demonstrated neuroprotective benefits in previous studies. This study aimed to explore the mechanisms through which AS-IV may treat cerebral ischemia-reperfusion injury (CIRI).

Background: Huntington disease (HD), a neurodegenerative autosomal dominant disorder, is characterized by involuntary choreatic movements with cognitive and behavioral disturbances. Up to now, no therapeutic strategies are available to completely ameliorate the progression of HD. has various pharmacologic effects such as antioxidant and anti-inflammatory activities.

Brain aging is a chronic process linked to inflammation, microglial activation, and oxidative damage, which can ultimately lead to neuronal loss. Sialic acid-binding immunoglobulin-like lectin-11 (SIGLEC-11) is a human lineage-specific microglial cell surface receptor that recognizes -2-8-linked oligo-/polysialylated glycomolecules with inhibitory effects on the microglial inflammatory pathways. Recently, the gene locus was prioritized as a top tier microglial gene with potential causality to Alzheimer's disease, although its role in inflammation and neurodegeneration remains poorly understood.

This study aimed to evaluate different combinations of three dietary supplements for potential additive or synergistic effects in an Parkinson's Disease model. The complex and diverse processes leading to neurodegeneration in each patient with a neurodegenerative disorder cannot be effectively addressed by a single medication. Instead, various combinations of potentially neuroprotective agents targeting different disease mechanisms simultaneously may show improved additive or synergistic efficacy in slowing the disease progression and allowing the agents to be utilized at lower doses to minimize side effects.

The recovery process following ischemic stroke is a complex undertaking involving intricate cellular and molecular interactions. Cellular dysfunction or aberrant pathways can lead to complications such as brain edema, hemorrhagic transformation, and glial scar hyperplasia, hindering angiogenesis and nerve regeneration. These abnormalities may contribute to long-term disability post-stroke, imposing significant burdens on both families and society.
