The use of neural stem cells (NSCs) or their progeny oligodendrocyte precursor cells (OPCs) represents a promising repair strategy for many neurological disorders. However, the molecular events and biological features during the transition from NSCs to OPCs remain unclear. In the present study, we isolated NSCs from the embryonic rat forebrain and induced(More)
Spinal cord neuronal culture is a useful system to study normal and abnormal functions of the spinal cord. For many bioassays, obtaining large quantities of highly purified spinal cord neurons is required. However, technical difficulties exist in obtaining these cells reliably and consistently. By comparing two dissociation methods, mechanical and enzymatic(More)
Post-traumatic inflammation response has been implicated in secondary injury mechanisms after spinal cord injury (SCI). Interleukin-1 (IL-1) is a key inflammatory mediator that is increasingly expressed after SCI. The action of IL-1 is mediated through its functional receptor, type I interleukin-1 receptor (IL-1RI). However, whether this receptor is(More)
BACKGROUND A long-term existing schistosome infection can aid in maintaining immuno-homeostasis, thus providing protection against various types of autoimmune diseases to the infected host. Such benefits have often been associated with acute or egg stage infection and with the egg-induced Th2 response. However, since schistosome infection undergoes(More)
The aim of this study was to establish the culture system of isolation and cultivation of the neural stem cells (NSCs) from the embryonic rat brain and spinal cord. The methods of microscopic dissection, cell culture and immunofluorescence cytochemistry were used. The results are as follows. (1) In the presence of fibroblast growth factor-2 (FGF-2) and(More)
The present study was conducted to investigate whether Ginkgo biloba extract (EGb) 761 could protect spinal cord neurons from H(2)O(2)-induced toxicity. In primary spinal cord neurons isolated from embryonic day 14 rats, H(2)O(2) administration resulted in a significant decrease in the survival of spinal cord neurons. Terminal deoxynucleotidyl(More)
The biological effects of interleukin (IL)-1 are mediated by two distinct receptors, the p80 or type I (IL-1RI) and p68 or type II (IL-1RII) receptors. Because IL-1RII has a short, 29-amino acid cytoplasmic domain which may not be sufficient for signaling, there is considerable evidence indicating that IL-1 may signal exclusively through the IL-1RI(More)
It has been well accepted that glycans present in schistosomes are highly antigenic. However, it is not clear what kind of worm glycans can affect the infected host to mount IgG responses and whether mounted anti-glycan IgG responses are protective. The contribution of antigenicity by glycans was measured by using competitive ELISA assay in sera from(More)
We have previously established a culture method to isolate and cultivate neural stem cells (NSCs) derived from the rat embryonic brain and spinal cord. In the present study, we demonstrate that the spinal cord-derived NSCs can be induced to differentiate into oligodendrocyte precursor cells (OPCs) with a combined treatment composed of (1) conditioned medium(More)
BACKGROUND Atherosclerosis (AS) is a common cardiovascular disease. Transformation of macrophages to form foam cells by internalizing modified low density-lipoprotein (LDL) via scavenger receptor (SR) is a key pathogenic process in the onset of AS. It has been demonstrated that SR-PSOX functions as either a scavenger receptor for uptake of atherogenic(More)
