The aggregation of Aβ42-peptides and the formation drusen in age-related macular degeneration (AMD) are due part to inability homeostatic phagocytic mechanisms clear self-aggregating from extracellular space. triggering receptor expressed myeloid/microglial cells-2 (TREM2), a trans-membrane-spanning, sensor-receptor immune-globulin/lectin-like gene superfamily is critical component Aβ42-peptide clearance. Here we report significant deficit TREM2 AMD retina cytokine- or oxidatively-stressed...
Murine transgenic models of Alzheimer's disease (Tg-AD) have been useful to analyze the contribution β-amyloid precursor protein (βAPP), Aβ42 peptide deposition, and proinflammatory mechanisms that characterize Alzheimer-type neuropathology. In this report, we studied levels βAPP, Aβ40 peptide, as well innate immune inflammatory response-regulator complement factor H in brain retina four different Tg-AD including Tg2576, PSAPP, 3xTg-AD, 5xFAD. Aged, symptomatic 5xFAD mice showed highest...
Genetic deficits and loss of function for the triggering receptor expressed in myeloid cells 2 (TREM2; encoded at chr6p21.1), a transmembrane spanning stimulatory immunoglobulin/lectin-like gene superfamily, have been associated with deficiencies phagocytosis innate immune system Alzheimer's disease. In this study, we provide evidence that TREM2 is downregulated samples sporadic Alzheimer hippocampal CA1 compared age-matched controls. A nuclear factor-кB (NF-кB)-sensitive miRNA-34a (encoded...

Alzheimer's disease is a progressive, neurodegenerative disorder that develops within the limbic system, spreading radially into anatomically linked brain association areas as progresses. Analysis of temporal-lobe neocortex-derived extracellular fluid and cerebrospinal from patients shows an abundant presence micro-RNA (miRNA), including proinflammatory miRNA-146a miRNA-155. Using novel highly sensitive LED-Northern dot-blot focusing technique, we detected secretion potentially pathogenic...
Docosahexaenoic acid (DHA, 22:6 n-3) is abundant in the retina and enzymatically converted into pro-homeostatic docosanoids. The DHA- or eicosapentaenoic (EPA)-derived 26 carbon fatty a substrate of elongase ELOVL4, which expressed photoreceptor cells generates very long chain (≥C28) polyunsaturated acids including n-3 (VLC-PUFAs,n-3). While ELOVL4 mutations are linked to vision loss neuronal dysfunctions, roles VLC-PUFAs remain unknown. Here we report novel class lipid mediators...
Down's syndrome, a congenital disorder associated with cognitive impairment and early-onset Alzheimer's disease, is progressive genetic pathology resulting from full or partial triplication of chromosome 21. syndrome brain typified by activated microglia, increases in inflammatory signaling, an aberrant immune system. In these studies, screening micro-RNA (miRNA) peripheral tissues indicated upregulation 21-encoded miRNA-155 decrease the abundance mRNA target complement factor H (CFH),...
We report the discovery of a novel family prohomeostatic and neuroprotective lipid mediators called elovanoids.
Abstract Temporal lobe epilepsy or limbic lacks effective therapies due to a void in understanding the cellular and molecular mechanisms that set motion aberrant neuronal network formations during course of epileptogenesis (LE). Here we show vivo rodent models LE phospholipid mediator platelet-activating factor (PAF) increases PAF receptor (PAF-r) ablation mitigates its progression. Synthetic PAF-r antagonists, when administered intraperitoneally LE, re-establish hippocampal dendritic spine...
Evolution of reactive oxygen species (ROS), generated during the patho-physiological stress nervous tissue, has been implicated in etiology several progressive human neurological disorders including Alzheimer’s disease (AD) and amylotrophic lateral sclerosis (ALS). In this brief communication we used mixed isomers 5-(and-6)-carboxy-2′,7′-dichlorofluorescein diacetate (carboxy-DCFDA; C25H14Cl2O9; MW 529.3), a novel fluorescent indicator, to assess ROS generation within neuronal-glial (HNG)...
