Molecular layer ectopias spontaneously occur in immune-disordered mice, and the accompanying paper demonstrates that these ectopias are associated with a break in the external glial limiting membrane and with distortion of radial glial fibers at birth. It was hypothesized that injury to the developing neocortex is the main etiologic event for molecular(More)
Forty percent of New Zealand Black (NZB) mice, a strain that develops severe autoimmune disease, have ectopic collections of neurons in layer I of the neocortex. This strain is used as a model for similar anomalies seen in the dyslexic brain. In the present study we immunohistochemically stained radical glial fibers and their anchoring processes (which form(More)
Two experiments investigated the heritability of neocortical ectopias seen in 30-40% of New Zealand Black (NZB/BINJ) autoimmune mice. The first study examined the brains of mice from the NZB x SM/J recombinant inbred (RI) strains. Fifteen RI inbred strains were examined and over half had ectopias suggesting that a major gene was involved in ectopia(More)
The transcription factor Pax6 is a well-accepted neurogenic determinant during development, in adult neural progenitor cells and in acute brain injury models. In the adult brain Pax6 is expressed in selective populations of dopaminergic neurons, and thus may have a role to play in Parkinson's disease (PD). This study looked at post-mortem tissue from(More)
Metalloproteinases are implicated in cleaving numerous proinflammatory mediators from the cell surface. Interestingly, the elevated levels of tumour necrosis factor-α (TNF-α) have been associated with the metabolic syndrome. We aimed to ascertain whether the human metalloproteinase ADAM28 correlates with parameters of the metabolic syndrome and whether(More)
Lyn is involved in erythropoietin (Epo)-receptor signaling and erythroid homeostasis. Downstream pathways influenced following Lyn activation and their significance to erythropoiesis remain unclear. To address this, we assessed a gain-of-function Lyn mutation (Lyn(up/up)) on erythropoiesis and Epo receptor signaling. Adult Lyn(up/up) mice were anemic, with(More)
Erythroid homoeostasis is primarily controlled by Epo (erythropoietin) receptor signalling; however, the Lyn tyrosine kinase plays an important subsidiary role in regulating the erythroid compartment. Nonetheless, specific erythroid pathways that require Lyn activity and their biological significance remain unclear. To address this, we asked what(More)
The focus of cell replacement therapies (CRTs) for Parkinson's disease has been on delivering dopamine-producing cells to the striatum. Fetal grafts have proven the feasibility of this approach, but an appropriate source of replacement cells has restricted the clinical translation. Bone marrow stromal cells (BMSCs) have been heralded as an ideal source of(More)
In an inbred genetic background, mice homozygous for a transgene insertion at perinatal lethality (ple) were found to be significantly smaller than their heterozygous or wild-type siblings at birth, and rarely survived for more than 48 h. Homozygous progeny of ple mice obtained from a cross with a different strain were viable, but were still not obtained in(More)
