Abstract excerpt
Synovial fibroblasts expressed transcripts for IL-4R alpha, and IL-13R alpha 1 and IL-13R alpha 2. Using weighted nonlinear computer modeling of the data from equilibrium binding studies, a 2 bindings sites model fitted the data best. After occupation of the shared high affinity receptors by the non-signaling, double mutant IL-4(121)R-->D, 124Y-->D (RY-IL-4) the high affinity binding of IL-13 could be abolished....
