TLRs sense various microbial products. Their function has been best characterized in DCs and macrophages, where they act as important mediators of innate immunity. TLR4 is also expressed on CD4+ T cells, but its physiological function on these cells remains unknown. Here, we have shown that TLR4 triggering on CD4+ T cells affects their phenotype and their(More)
BACKGROUND Population pharmacokinetic (PK) studies of busulfan in children have shown that individualized model-based algorithms provide improved targeted busulfan therapy when compared with conventional dose guidelines. The adoption of population PK models into routine clinical practice has been hampered by the tendency of pharmacologists to develop(More)
For children receiving allogeneic hematopoietic stem cell transplants (HSCTs), the toxicity of the conditioning regimen and graft failure remain challenges. We previously reported that targeted i.v. busulfan, fludarabine, and rabbit anti-thymocyte globulin (rATG) decreased toxicity but had a graft failure rate of 21%. To improve the engraftment rate, we(More)
The interleukin 1 receptor (IL-1R) and the Toll-like receptors (TLRs) are highly homologous innate immune receptors that provide the first line of defense against infection. We show that IL-1R type I (IL-1RI) is essential for TLR9-dependent activation of tumor necrosis factor receptor-associated factor 3 (TRAF3) and for production of the antiinflammatory(More)
PURPOSE To evaluate the role of radiation therapy (RT) as a component of multimodality therapy for pediatric desmoids. METHODS AND MATERIALS Twenty-one children diagnosed between 1987 and 2005 were identified. Median age at start of treatment was 13 years (range, 2-21). Primary therapy consisted of resection alone (10), resection + external beam radiation(More)
PURPOSE To investigate the association of single-nucleotide polymorphisms (SNPs) in the manganese superoxide dismutase (MnSOD) and two chemokine genes (CCL2 and CCL5) in patients with anterior uveitis (AU). METHODS Seventy-nine Chinese patients with acute AU were recruited, and genotyping of four SNPs including MnSOD 47, CCL2 -2518, CCL2 -2076, and CCL5(More)
This paper investigates the cache sizes and configurations that can be supported by a high frequency processor of the next generation. Based on the SIA roadmap prediction that a 0.1u processor of the next generation will run at 3.5GHz, we model caches of that technology using the CACTI tool. Access times as well as energy consumption are modeled for caches(More)
BACKGROUND CD3δ deficiency is a fatal form of severe combined immunodeficiency that can be cured by hematopoietic stem cell transplantation (HSCT). The presence of a thymus loaded with T-cell progenitors in patients with CD3δ deficiency may require special considerations in choosing the regimen of conditioning and the type of HSCT. OBJECTIVES To study the(More)
