Figure 5.
GRα/GRβ heterodimers are present in neutrophils. The GRα protein in neutrophils and PBMCs were immunoprecipitated with a GRα-specific antibody, then Western blotted with an anti-GRβ–specific antibody. PBMCs showed weak bands indicating low levels of heterodimers (lanes 1–4). In contrast, neutrophils demonstrated strong GRβ staining, indicating a high level of GRα/GRβ heterodimers (lanes 5–8).
