TOLL-interacting Protein in Pulmonary Diseases: Abiding by the Goldilocks Principle.

abstract：:Adenosine concentrations are elevated in the lungs of patients with asthma and chronic obstructive pulmonary disease, where it balances between tissue repair and excessive airway remodeling. We previously demonstrated that the activation of the adenosine A2A receptor promotes epithelial wound closure. However, the mec...
