Interleukin 15 Controls both Proliferation and Survival of a Subset of Memory-Phenotype CD8+ T Cells
Previous work has shown that memory-phenotype CD44(hi) CD8(+) cells are controlled by a cytokine, interleukin (IL)-15. However, the dependency of CD44(hi) CD8(+) cells on IL-15 is partial rather than complete. Here, evidence is presented that CD44(hi) CD8(+) cells comprise a mixed population of IL-15-dependent and IL-15-independent cells. The major subset of CD122(hi) CD44(hi) CD8(+) cells is h...
The mouse lymphoid organ-resident CD8alpha(+) dendritic cell (DC) subset is specialized in Ag presentation to CD8(+) T cells. Recent evidence shows that mouse nonlymphoid tissue CD103(+) DCs and human blood DC Ag 3(+) DCs share similarities with CD8alpha(+) DCs. We address here whether the organization of DC subsets is conserved across mammals in terms of gene expression signatures, phenotypic ...
The white blood cell DNA of 36 cord blood samples with Hb Bart’s in the red blood cells was studied for a-globin gene deletions by hybridization of DNA fragments digested by the restriction endonucleases Eco RI, Hpa I. Bam HI, and Bgl II. All 16 DNA samples from cord blood with Hb Bart’s below 3% and no other abnormal hemoglobin had one a-globin gene deletion (athal2), except one which had two ...
due to the widespread applications of xylitol dehydrogenase, an enzyme used for the production of xylitol, the present study was designed for the cloning of xylitol dehydrogenase gene from glcunobacter oxydans dsm 2003. after extraction of genomic dna from this bacterium, xylitol dehydrogenase gene was replicated using polymerase chain reaction (pcr). the amplified product was entered into ptz5...
BACKGROUND Vascular endothelial growth factor (VEGF) stimulates vascular genesis and angiogenesis. Cerebral Hypoxia-Ischemia (HI) leads to the reduction of vasculature in the cerebral cortex of newborn piglets. OBJECTIVE The present study tests the hypothesis that post-hypoxia intranasal administration of recombinant human VEGF165 (rh-VEGF165) for 3 days increases the vascular density in the ...
This study was conducted to detect the presence ofseJA gene among Salmonella Enteritidis isolates from poultry sources by polymerase chain reaction (Pf'R) and evaluate its potential as diagnostic and epidemiological tools. Thirty Salmonella isolates from poultry sources: broilers. broiler breeders, layers, hatcheries, and poultry abattoirs were investigated. Upper and forward primers were const...
