Megjegyzések:	The heterodimeric receptor complex of IL-9 consists of the cytokine-speci?c ?-subunit and the common ? -chain shared with other cytokines, including IL-2, a central regulator of T cell function. We have shown previously the bipartite spatial relationship of IL-9 and IL-2 receptors at the surface of human T lymphoma cells: in addition to common clusters, expression of the two receptor kinds could also be observed in segregated membrane areas. Here we analyzed further the mutual cell surface organization of IL-9 and IL-2 receptors. Complementing Pearson correlation data with co-occurrence analysis of confocal microscopic images revealed that a minimum degree of IL-9R/IL-2R co-localization exists at the cell surface regardless of the overall spatial correlation of the two receptor kinds. Moreover, our FRET experiments demonstrated molecular scale assemblies of the elements of the IL-9/IL-2R system. Binding of IL-9 altered the structure and/or composition of these clusters. It is hypothesized, that by sequestering receptor subunits in common membrane areas, the overlapping domains of IL-9R and IL-2R provide a platform enabling both the formation of the appropriate receptor complex as well as subunit sharing between related cytokines.
