Description: IBE-667 is an ICAM-1 binding enhancer for LFA-1. Cellular assays demonstrate the activity of IBE-667 in promoting the binding of LFA-1 on activated immune cells to ICAM-1. IBE-667 increases the binding of biotinylated soluble ICAM-1 to activated T-cells as determined by staining with PE-streptavidin and FACS analysis. IBE-667 leads to a concentration dependent induction of T-cell aggregation after activation by anti CD3 and anti CD28 antibodies. IBE-667 induced T-cell aggregation can be completely reversed with an LFA-1 neutralizing antibody.
