ADMA concentrations are augmented in lung, plasma samples of asthmatics. It remains unclear whether the increased concentration of ADMA in airway inflammation contributes to the pathophysiology or acts as a protective mechanism. The objective of this study was to evaluate the effects of exogenous ADMA on airway inflammation in mice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Ex vivo\/in vivo airway inflammation models were used. Tracheal tissues, isolated from female Balb\/c mice were incubated with lipopolysaccharide (LPS), ADMA, or LPS\u2009+\u2009ADMA for 4 days in tissue culture. Tracheal reactivity was evaluated afterward by agonist-induced contraction responses. Female Balb\/c mice were applied i.n. LPS (0,1\u00a0mg\/ml) to induce in vivo airway inflammation. ADMA (30\u00a0mg\/kg) was administered by i.n. route 1 h before and 24\u00a0h after LPS application.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key findings<\/jats:title>\n                    <jats:p>I.n. ADMA application augmented lung ADMA levels, reduced nitrite levels in bronchoalveolar lavage (BAL) fluid, prevented bronchial hyperreactivity and airway inflammation.
