In this study, we investigated regulatory role mammalian target rapamycin (mTOR) on nuclear factor κB (NF-κB) in mice DE, and neuroprotective effect therapeutic mechanisms luteolin, natural flavonoid compound anti-inflammatory, antioxidant, properties. The results indicated that treatment luteolin improved degree cognitive impairment DE.

Disorders of metabolism affect multiple systems throughout the body but may have greatest impact on both central and peripheral nervous systems. Currently available treatments behavior changes for disorders that include diabetes mellitus (DM) system diseases are limited cannot reverse disease burden. Greater access to healthcare a longer lifespan led an increased prevalence metabolic neurodegenerative disorders. In light these challenges, innovative studies into underlying pathways offer new treatment perspectives Alzheimer's Disease, Parkinson's Huntington's Disease. Metabolic intimately tied can lead debilitating outcomes, such as multi-nervous disease, susceptibility viral pathogens, long-term cognitive disability. Novel strategies robustly address involve careful consideration cellular metabolism, programmed cell death pathways, mechanistic target rapamycin (mTOR) its associated mTOR Complex 1 (mTORC1), 2 (mTORC2), AMP-activated protein kinase (AMPK), growth factor signaling, risk factors apolipoprotein E (APOE-ε4) gene.

Failure a normal pro-inflammatory immune response to resolve lead persistent central contributes unsuccessful clearance amyloid-beta plaques as they form, neuronal death, and ultimately cognitive decline. Individual metabolic, dietary (lipid) profiles can differentially regulate this inflammatory process with aging, obesity, poor diet, early life stress other factors contributing greater risk developing AD. Here, we integrate evidence for interface between these factors, how contribute brain milieu. In particular, discuss importance appropriate polyunsaturated fatty acids (PUFA) in diet metabolism specialised pro-resolving mediators (SPMs); raising possibility strategies improve outlook.

Abstract In the context of global ageing, prevalence neurodegenerative diseases and dementia, such as Alzheimer’s disease (AD), is increasing. However, current symptomatic disease-modifying therapies have achieved limited benefits for in clinical settings.

Thus, we aim to elucidate role ageing from perspective a complex system, which brain core peripheral organs tissues form holistic network support functions.

Abstract INTRODUCTION The molecular mechanisms that contribute to sex differences, in particular female predominance, Alzheimer's disease (AD) prevalence, symptomology, and pathology, are incompletely understood. METHODS To address this problem, we investigated cellular metabolism immune responses (“immunometabolism endophenotype”) across AD individuals as a function of with diverse clinical diagnosis cognitive status at death (cogdx), Braak staging, Consortium Establish Registry for (CERAD) scores using human cortex metabolomics transcriptomics data from the Religious Orders Study / Memory Aging Project (ROSMAP) cohort. RESULTS We identified sex‐specific metabolites, metabolic genes, pathways associated progression. female‐specific elevation glycerophosphorylcholine N‐acetylglutamate, which inflammatory metabolites involved interleukin (IL)‐17 signaling, C‐type lectin receptor, interferon Toll‐like receptor pathways. pinpointed distinct microglia‐specific immunometabolism endophenotypes (i.e., lipid‐ amino acid‐specific IL‐10 IL‐17 signaling pathways) between male subjects. In addition, subjects showed evidence diminished excitatory neuron microglia communications via glutamate‐mediated immunometabolism. DISCUSSION Our results point new understanding basis predominance AD, warrant future independent validations ethnically patient cohorts establish likely causal relationship microglial differences AD.

For much of human evolution, the average lifespan was <40 years, due in part to disease, infant mortality, predators, food insecurity, and, for females, complications childbirth. Thus, many females did not reach age menopause (45–50 years age) and it is mainly past several hundred that has been extended >75 primarily public health advances, medical interventions, antibiotics, nutrition. Therefore, underlying biological mechanisms responsible disease risk following must have evolved during complex processes leading Homo sapiens serve functions pre-menopausal state. Furthermore, as a primary function survival species effective reproduction, likely most advantages having such post-menopausal risks relate reproduction ability address environmental stresses. This opinion/perspective will be discussed context how could enhance with improved offspring, perhaps why are preserved. Not all exhibit this set diseases, those who do develop diseases conditions. The state operate unified complex, but independent variables, potential some overlap. there would heterogeneity if factors essential reproductive also concept sets reversible epigenetic changes associated puberty, pregnancy, lactation offered explain observations regarding distribution conditions their roles reproduction. While involvement an system dynamic “modification-demodification-remodification” paradigm contributing hypothesis at point, validation lead better understanding commonalities may future interventions control after menopause.

Female reproductive hormones are found to be essential cellular activities in brain. physiological role neurotrophins and sex hippocampal region during neurogenesis neuron differentiation was studied as well. In addition triggering pathways, estrogen progesterone carry out a number biological processes that lead neuroprotection. They might have an impact on learning memory. One estrogen's modest antioxidant properties its direct scavenging free radicals. neurotrophic effect can explained by their ability rise expression brain-derived factor (BDNF) mRNA. Additionally, they degrade beta-amyloid stop inflammation, apoptotic neuronal cell death, tau protein phosphorylation. To enhance neuroprotective action, various cross-talking pathways cells mediated estrogen, progesterone, BDNF receptors. This include signaling mitogen-activated kinase/extracellular regulated kinase, phosphatidylinositol 3-kinase/protein kinase B, phospholipase/protein C. Clinical research establish significance these substances fragmented, despite publications claiming lower prevalence AD when medication started before menopause. review article emphasizes update AD.
