Influence of intra-tracheal instillation of exogenous IL-1β treatment on (A) NGF and (B) SP protein levels in bronchoalveolar lavage fluid. Protein levels were measured by ELISA 24 h after saline or IL-1β (200 μl/ml) treatment. (A) NGF levels and (B) SP levels in lung lavage fluid. Values are means ± SE of 5–6 mice/group. Asterisk indicates significant difference between NGF levels in saline- and IL-1β-treated animals, p ≤ .05.
