Assessment of platelet basal activation state and its functional competence in ITP patients and controls. (A) P-selectin expression, (B) PAC-1 binding, (C) and ROS generation in individuals with ITP (blue) compared to healthy controls (gray) at baseline and after agonist treatment. Red asterisks show statistical differences of each agonist group vs., the related base group, while black asterisks illustrate statistical differences between ITP (n = 28) and control (n = 20). *P <.05, **P <.01, and ***P <.001. Data presented as mean ± SD. CCCP, carbonyl cyanide m-chlorophenylhydrazone; PMA, Phorbol 12-Myristate 13-Acetate; ROS, Reactive Oxygen Species.
