Abstract Background Idiopathic pulmonary arterial hypertension IPAH is a progressive and still incurable disease. Research of IPAH-pathogenesis is complicated by the lack of a direct access to the involved tissue the human pulmonary vasculature. Various auto-antibodies have been described in the blood of patients with IPAH. The purpose of the present work was therefore to comparatively analyze peripheral blood B lymphocyte RNA expression characteristics in IPAH and healthy controls. Methods Patients were diagnosed having IPAH according to WHO mean pulmonary arterial pressure 25 mmHg pulmonary capillary occlusion pressure 15 mmHg absence of .
