Alzheimer’s Disease (AD) is a debilitating neurodegenerative condition with limited treatment options. Lignans, class of naturally occurring polyphenols found in various plants, have been shown to the potential modulate pathways associated AD pathology. In this study, we used network pharmacology and molecular docking investigate therapeutic lignans against by targeting specific proteins involved disease progression.

Mass spectrometry (MS) has revolutionized clinical chemistry, offering unparalleled capabilities for biomolecule analysis. This review explores the growing significance of mass (MS), particularly when coupled with liquid chromatography (LC), in identifying disease biomarkers and quantifying biomolecules diagnostic prognostic purposes. The unique advantages MS accurately diverse molecules have positioned it as a cornerstone personalized-medicine advancement. MS-based technologies transformed precision medicine, enabling comprehensive understanding mechanisms patient-specific treatment responses. LC-MS shown exceptional utility analyzing complex biological matrices, while high-resolution expanded analytical capabilities, allowing detection low-abundance elucidation pathways. integration other techniques, such ion mobility spectrometry, opened new avenues biomarker discovery validation. As we progress toward will be crucial addressing challenges individualized patient care, driving innovations diagnosis, prognosis, strategies.

Astrocytes are the major glial cells in human brain and provide crucial metabolic trophic support to neurons. The amyloid-β peptide (Aβ) alter morphological functional properties of astrocytes induce inflammation calcium dysregulation, contributing Alzheimer's disease (AD) pathology. Recent studies highlight role Toll-like receptor (TLR) 4/nuclear factor kappa-light-chain-enhancer activated B (NF-κB) signaling inflammation. Reactive oxygen species (ROS) generated due Aβ, apoptosis worsening AD progression. Astrocytic cell surface receptors, such as purinergic receptors (P2Y1 P2Y2), metabotropic glutamate (mGLUR)5, α7 nicotinic acetylcholine (α7nAChR), N-methyl-d-aspartate (NMDARs), have been suggested interact with inositol trisphosphate (IP3R) on endoplasmic reticulum (ER) Ca2+ movement from ER cytoplasm, causing dysregulation. We found that citrus flavonoid nobiletin (NOB) protected primary Aβ42-induced cytotoxicity inhibited TLR4/NF-κB rat astrocytes. NOB was regulate ROS levels through Keap1-Nrf2 pathway. P2Y1, P2Y2, mGLUR5, α7nAChR, NMDARs induced intracellular by activating IP3R regulated them, thereby regulating levels. Molecular docking analysis revealed a possible interaction between regulation. Furthermore, RNA sequencing various NOB-mediated biological pathways, AD-presenilin, AD-amyloid secretase, Wnt pathway, suggesting neuroprotective roles NOB.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder, and its early detection can be critical for prompt intervention that potentially slow down the progression improve patient's quality of life. However, diagnosis based solely on clinical symptoms challenging, especially in stages, while specific biomarkers such as amyloid-β peptide (Aβ) tau proteins provide objective evidence diagnosis. In this work, we explored effects Aβ cell membrane properties thanks to fluorescence lifetime imaging (FLIM) combined with phasor analysis (FLIM-ϕ). The results showed viscosity altered by presence cells experience effect even at nanomolar concentrations peptide. This considerable sensitivity opens up possibility envisioning cell-based biosensor able detect very low biological fluid, thus enabling timely intervention.

Alzheimer's disease (AD) diagnosis relies on cerebrospinal fluid (CSF) biomarkers or amyloid PET. Alternatives for AD from blood samples are needed to develop a fully-automated early-diagnosis approach, potentially implemented in cognitive disorder unit. Plasma p-Tau217 was determined patients diagnosed with (n = 134) non-AD 132), CSF (Aβ42/Aβ40). A logistic regression model developed. The predictive performance assessed using training set (70% of data) and internally validated test (30% 1000 iterations. nomogram double cut-off strategy were proposed visualize the results, stratify (AD, non-AD, uncertain), respectively.

Abstract Previous studies have shown that glial and neuronal changes may trigger synaptic dysfunction in Alzheimer’s disease(AD). However, the link between markers abnormalities living brain is poorly understood. Here, we investigated association biomarkers of astrocyte microglial reactivity 478 individuals across aging AD spectrum from two cohorts with available CSF measures amyloid-β(Aβ), phosphorylated tau(pTau181), reactivity(GFAP), activation(sTREM2), biomarkers(GAP43 neurogranin). Elevated GFAP levels were linked to presynaptic postsynaptic dysfunction, regardless cognitive status or Aβ presence. sTREM2 associated cognitively unimpaired impaired + individuals. Notably, pTau181 mediated all associations biomarkers. These results suggest neuronal-related could be used clinical trials targeting AD.

Abstract Alzheimer's disease (AD) is a multifactorial in which environmental factors play role. Among factors, air pollution vital issue modern life. Despite extensive considerations, it remains uncertain how mediates neurodegeneration AD. Beta‐amyloids and hyperphosphorylated tau proteins are the two main pathological markers that have been studied AD so far. Tau protein basically phosphoprotein whose functions controlled by phosphorylation. The function of to be located on surface microtubules stabilize them. Studies shown phosphorylated (p‐tau) exists cis trans conformations at Thr231, among highly neurotoxic. Pin1 enzyme performs conversion or vice versa. In this study, an experimental mouse model was designed investigate formation p‐tau inducing pollution. way, mice were randomly exposed 2‐week, 1‐month, 2‐month intervals.
