The strategic axes play a vital role in the network by bringing together, around unifying research themes, researchers interested in pathophysiological mechanisms of a similar nature that group together several pulmonary diseases. The axes play a key role in the scientific life of the network to promote the exchange of ideas, establish collaborations with researchers with complementary expertise and lead to the realization of innovative projects or the development of new therapeutic avenues. The axes also play an important role in the consultation process aimed at targeting research areas considered to be priorities in respiratory health.
