In the absence of a fully effective herpes simplex virus (HSV) vaccine, topical microbicides represent an important strategy for preventing HSV transmission. (-)-Epigallocatechin gallate (EGCG) (molecular weight, 458.4) is the primary catechin in green tea. The present study shows that EGCG has greater anti-HSV activity than other green tea catechins and(More)
Abnormal hyperphosphorylation of the microtubule-associated protein Tau is a hallmark of Alzheimer disease and related diseases called tauopathies. As yet, the exact mechanism by which this pathology causes neurodegeneration is not understood. The present study provides direct evidence that Tau abnormal hyperphosphorylation causes its aggregation, breakdown(More)
The synthesis of a water/plasma soluble, noncytotoxic, "clicked" sugar-derivative of curcumin with amplified bioefficacy in modulating amyloid-β and tau peptide aggregation is presented. Curcumin inhibits amyloid-β and tau peptide aggregation at micromolar concentrations; the sugar-curcumin conjugate inhibits Aβ and tau peptide aggregation at concentrations(More)
Alzheimer's disease is a progressive neurodegenerative disease that is characterized histopathologically by the presence of plaques, mainly composed of Abeta amyloid and the tangles, mainly composed of hyperphosphorylated tau. To date, there is no treatment that can reverse the disease, and all the current therapeutics is directed to cope with the symptoms(More)
The hyperphosphorylated microtubule-associated protein tau is present in several neurodegenerative diseases, although the causal relationship remains elusive. Few mouse models used to study Alzheimer-like dementia target tau phosphorylation. We created an inducible pseudophosphorylated tau (Pathological Human Tau, PH-Tau) mouse model to study the effect of(More)
BACKGROUND The present patent deals with the generation of peptides derived from the activity-dependent peptide and tau mimetic to study its effect on microtubule stability, its ability to bind to tubulin and MAPs, as well as promoting cell survival. OBJECTIVE To analyze these peptides and their effects as potential therapeutic elements for(More)
It has been shown that a marked increase in the levels of RI alpha sub-units and a decrease in RII beta sub-unit levels correlate with neoplastic transformation or with the mitogenic response of normal cells to hormones and growth factors. The selective down-regulation of RI alpha and the following induction of RII beta determine cell-growth arrest and(More)
INTRODUCTION Accumulation of hyperphosphorylated tau and the disruption of microtubules are correlated with synaptic loss and pathology of Alzheimer's disease (AD). Impaired cognitive function and pathology of AD is correlated with this lesion. This review looks at the mechanism of neurodegeneration, the prion-like behavior of tau in its interaction with(More)
Cellular composition of the adult zebrafish (Danio rerio) optic tectal cortex was examined in this study. Morphological techniques such as 1 μm thick serial plastic sections stained with osmium tetroxide and toluidine blue, modified rapid Golgi silver impregnation, GFAP immunohistochemistry, confocal microscopy, as well as scanning and transmission electron(More)
Tau is a microtubule-associated protein mainly found in neurons. The protein is associated with process of microtubule assembly, which plays an important role in intracellular transport and cell structure of the neuron. Tauopathies are a group of neurodegenerative diseases specifically associated with tau abnormalities. While a well-defined mechanism(More)
