The effects of dsRNA mycoviruses on growth and murine virulence of Aspergillus fumigatus
(2011-11)
Some isolates of the opportunistic human pathogenic fungus Aspergillus fumigatus are known to be infected with mycoviruses. The dsRNA genomes of two of these mycoviruses, which include a chrysovirus and a partitivirus, ...
Sulforaphane protects cortical neurons against 5-S-cysteinyl-dopamine-induced toxicity through the activation of ERK1/2, Nrf-2 and the upregulation of detoxification enzymes
(2010-04)
The degeneration of dopaminergic neurons in the substantia nigra has been linked to the formation of the endogenous neurotoxin 5-S-cysteinyl-dopamine. Sulforaphane (SFN), an isothiocyanate derived from the corresponding ...
The citrus flavanone naringenin inhibits inflammatory signalling in glial cells and protects against neuroinflammatory injury
(2009-04-01)
Neuroinflammation plays an integral role in the progression of neurodegeneration. In this study we investigated the anti-inflammatory effects of different classes of flavonoids (flavanones, flavanols and anthocyanidins) ...
Glial metabolism of quercetin reduces its neurotoxic potential
(2008-10-15)
The neuroprotective effects of flavonoids will ultimately depend on their interaction with both neuronal and glial cells. In this study, we show that the potential neurotoxic effects of quercetin are modified by glial cell ...
Peroxynitrite induced formation of the neurotoxins 5-S-cysteinyl-dopamine and DHBT-1 : implications for Parkinson's disease and protection by polyphenols
(2008-08-15)
Mechanisms of nigral cell injury in Parkinson's disease remain unclear, although a combination of increased oxidative stress, the formation of catecholamine-quinones and the subsequent formation of neurotoxic cysteinyl-c ...
Activation of pro-survival Akt and ERK1/2 signalling pathways underlie the anti-apoptotic effects of flavanones in cortical neurons
(2007-11)
There is growing interest in the potential beneficial effects of flavonoids in the aging and diseased brain. We have investigated the potential of the flavanone hesperetin and two of its metabolites, hesperetin-7-O-beta- ...
The phagocytic capacity of neurones
(2007-05)
Phagocytosis is defined as the ingestion of particulates over 0.5 microm in diameter and is associated with cells of the immune system such as macrophages or monocytes. Neurones are not generally recognized to be phagocytic. ...
Champagne wine polyphenols protect primary cortical neurons against peroxynitrite-induced injury
(2007-04-18)
White wines are generally low in polyphenol content as compared to red wines. However, Champagne wines have been shown to contain relatively high amounts of phenolic acids that may exert protective cellular actions in vivo. ...
Systemic delivery of morpholino oligonucleotide restores dystrophin expression bodywide and improves dystrophic pathology
(2006)
For the majority of Duchenne muscular dystrophy (DMD) mutations, antisense oligonucleotide (AON)-mediated exon skipping has the potential to restore a functional protein. Here we show that weekly intravenous injections of ...
Sensing of lysophospholipids by TRPC5 calcium channel
(2006)
TRPC calcium channels are emerging as a ubiquitous feature of vertebrate cells, but understanding of them is hampered by limited knowledge of the mechanisms of activation and identity of endogenous regulators. We have ...
