Comparison of Gene Expression Patterns Induced by Treatment of Human Umbilical Vein Endothelial Cells with IFN- α 2b vs. IFN- β 1a: Understanding the Functional Relationship Between Distinct Type I Interferons That Act Through a Common Receptor

Abstract excerpt

We analyzed whether interferon-alpha 2b (IFN-alpha 2b) and IFN-beta 1a engage their common receptor to generate activated receptor complexes possessing distinct signaling properties. Human vascular endothelial cells (HUVEC) are 100-1000-fold more sensitive to IFN-beta 1a than to IFN-alpha 2b in in vitro assays. An nonarray-based expression profiling (GeneCalling) technology was employed to compare the patterns...
