Mechanisms of the anti-inflammatory and antifibrotic activity of a sympatholytic agent during toxic pulmonary fibrosis.


PMID 23113245

Abstract

The effect of a course treatment with a sympatholytic reserpine on the inflammatory response and connective tissue proliferation in the lungs of C57Bl/6 mice was studied on the model of toxic pulmonary fibrosis induced by intratracheal administration of bleomycin. This sympatholytic reduced infiltration of the alveolar interstitium and alveolar ducts with inflammatory cells (lymphocytes, macrophages, neutrophils, and plasma cells) and prevented connective tissue proliferation in the lungs. The anti-inflammatory effect of reserpine was associated with a decrease in activity of bone marrow granulocyte-erythroid-macrophage-megakaryocyte and granulocyte precursors (proliferation and mobilization). The antifibrotic effect of reserpine was due to a decrease in the number of committed precursors for mesenchymopoiesis.
