Abstract

The anti-inflammatory cholinergic system (SCAI), described a few years ago, has been not fully investigated in the lung and may be an important therapeutic target for the treatment of pulmonary diseases. We recently demonstrated that animals with VAChT deficiency, the protein which transports acetylcholine (ACh), developed inflammation, activation of the NF-kB and reduction of JAK2-STAT3-SOCS3 pathway in lung. The reduction of VAChT also increased lung inflammation in an experimental model of asthma and emphysema. Based on that, several questions have appeared in order to better understand the role of cholinergic anti-inflammatory system in lung and also to evaluate new possible therapeutic targets involved in these diseases. This study aims to advance the understanding of SCAI in chronic and acute pulmonary responses, and make progress on this line of research poorly investigated in lung. Objectives: 1. Evaluate whether the long-term VAChT reduction interfere in the lung inflammation in naïve mice; 2 Evaluate the effect of genetic reduction of VAChT in an experimental model of acute inflammation; 3. Evaluate the effect of nicotinic receptor stimulation in the acute inflammation model; 4. Evaluate the effects of nicotinic receptor stimulation in experimental asthma model; 5 Evaluate whether SCAI is involved in the effects of a flavonoid sakuranetin in attenuating lung inflammation in an experimental asthma model. 6 Evaluate the effects of nicotinic receptor stimulation in experimental emphysema model. For that, VAChT strain mice with reduced cholinergic tone, C57BL and Balb-C mice will be used and lung function, pulmonary histopathology and mechanisms involved in acute lung injury and experimental asthma and lung emphysema models will be evaluated.
