Telocyte-derived exosomes ameliorated the severity of LPS-induced pulmonary edema, nourished airway epithelial cells, increased epithelial cell proliferation, and enhanced the expressions of protein kinase B (AKT), HIF-1α, and VEGF-A proteins in human bronchial epithelial cells (92). The gene discussed is AKT1; the disease is pulmonary edema.
