Expression of phosphorylated platelet-derived growth factor receptor in the papillary dermis following rituximab administration. Rituximab (RTX) mediates a significant attenuation in platelet-derived growth factor receptor (PDGFR) phosphorylation (activation) status. (A) Phospho-PDGFRα and (B) phospho-PDGFRβ expression is decreased following RTX administration.
