Asthma is a chronic inflammatory airway disease, in which purinergic signaling has a central role, controlling activation of structural and hematopoietic cells. Aerobic exercise (AE) present anti-inflammatory effects to the airways, but no cellular and molecular mechanisms are known. Thus, this project evaluated the effects of AE on purinergic signaling response in a model of asthma induced by house dust mite (HDM). AE was performed in a treadmill at moderate intensity, 5x/week, during 4 weeks, after 3 weeks of prior HDM administration. HDM (dermatophagoides pteronyssinus; 100mg/mouse) was administered 3x/week, during 7 weeks. The results demonstrated that AE reduced ATP accumulation (p |
