Parkinson's disease (PD) is a complex disease, with genetics and environment contributing to the disease onset. Recent studies of causative PD genes have confirmed the involvement of cellular mechanisms engaged in mitochondrial and UPS dysfunction, oxidative stress and apoptosis in the progressive degeneration of the dopaminergic neurons in PD. In addition,(More)
Parkin Co-Regulated Gene (PACRG) is a novel gene that is oriented in a head-to-head array with parkin, and expression of the two genes is regulated by a shared bi-directional promoter. Mutations in parkin are the most common cause of early-onset autosomal recessive Parkinson's disease, however the function of PACRG and potential role in the pathogenesis of(More)
We have previously identified an increased susceptibility of glutathione peroxidase-1 (Gpx1)-/- mice to neuronal apoptosis following mid-cerebral artery (MCA) occlusion. This study was designed to elucidate the mechanisms involved in elevated neuronal cell death arising from an altered endogenous oxidant state. This was addressed in both an in vitro and in(More)
Mutations in parkin are a common cause of early-onset autosomal recessive Parkinson's disease. Parkin Co-Regulated Gene (PACRG) is a novel gene that was discovered because of its close genetic proximity to parkin and the two genes were subsequently demonstrated to be regulated by a bi-directional promoter. However the role of PACRG has not been well(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disease and the most common cause of dementia. Deposition of amyloid-β (Aβ) remains a hallmark feature of the disease, yet the precise mechanism(s) by which this peptide induces neurotoxicity remain unknown. Neuroinflammation has long been implicated in AD pathology, yet its contribution to disease(More)
A neuro-inflammatory response has been implicated in human patients and animal models of Alzheimer's disease (AD). Type-1 interferons are pleiotropic cytokines involved in the initiation and regulation of the pro-inflammatory response; however, their role in AD is unknown. This study investigated the contribution of type-1 IFN signaling in the(More)
Neuro-inflammation has long been implicated as a contributor to the progression of Alzheimer’s disease in both humans and animal models. Type-1 interferons (IFNs) are pleiotropic cytokines critical in mediating the innate immune pro-inflammatory response. The production of type-1 IFNs following pathogen detection is, in part, through the activation of the(More)
Type-1 interferons (IFNs) are pleiotropic cytokines that signal through the type-1 IFN receptor (IFNAR1). Recent literature has implicated the type-1 IFNs in disorders of the CNS. In this study, we have investigated the role of type-1 IFNs in neuroinflammation following traumatic brain injury (TBI). Using a controlled cortical impact model, TBI was induced(More)
Hypoxic-ischaemic injuries such as stroke and traumatic brain injury exhibit features of a distinct neuro-inflammatory response in the hours and days post-injury. Microglial activation, elevated pro-inflammatory cytokines and macrophage infiltration contribute to core tissue damage and contribute to secondary injury within a region termed the penumbra.(More)
Parkin Co-Regulated Gene (PACRG) is a gene that shares a bi-directional promoter with the Parkinson's disease associated gene parkin. The functional role of PACRG is not well understood, although the gene has been associated with parkinsonian syndromes and more recently with eukaryotic cilia and flagella. We investigated the expression of Pacrg in the mouse(More)
