| Severe acute respiratory syndrome (SARS) emerged in 2003, as a new epidemic form of life-threatening infection. As of 26th September 2003, there were 8422 cases of SARS from 29 countries with 908 deaths (WHO). However, the pathogenesis of SARS is poorly understood. To understand the host response to this pathogen, we profiled the gene expression patterns of peripheral blood mononuclear cells (PBMC) from SARS patients compared to healthy controls using one of the latest techniques, high density oligonucleotide expression probe array (HG-Focus array, Gene Chip, Affymetrix, Santa Clara, CA). High-density oligonucleotide microarray is a promising approach for high throughput analysis. It has been extensively
used in many areas of biomedical... |

| Systemic anaphylaxis is considered to be a typical immediate hypersensitivity response, determined by the activation of immune cells,
via antigen-induced aggregation of IgE-sensitized FcεRI cells. Perhaps most the important cells, in the immediate hypersensitivity responses, are mast cells. We have previously shown that SPHK1 plays a key role in the intracellular signaling pathways triggered by FceRI aggregation on human
mast cells. More recently, we performed a genome-wide gene expression profiling of human mast cells, sensitized with IgE alone, or stimulated by FcεRI aggregation. We found that sphingosine kinase 1 (SPHK1) was one
of genes activated at the earlier stages of mast cell... |
