Abstract
The pathophysiology of PAH is not fully elucidated and no curative treatment is yet available. However, the presence of inflammatory cells and the intense release of inflammatory mediators in pulmonary PAH lesions, associated with the high level of pro-inflammatory cytokines and of autoantibodies targeting vascular components in the sera of patients, raise the question of the involvement of inflammation and autoimmunity in the initiation, the perpetuation, and/or the worsening of the disease. This review covers PAH immunopathological aspects with a special emphasis on the role of inflammation on the pulmonary vascular remodeling, the potential immunopathological mechanisms of PAH, the relevance of inflammatory mediators as prognostic and predictive markers in PAH, and on the immunomodulatory properties of current PAH therapies.
