Effects of Montelukast on Airway Regulatory T Cells in Asthma
Overview[ - collapse ][ - ]
Purpose | Montelukast is one of anti-inflammatory agents and a good controller for the patients with asthma. The hypothesis of the study is that the Montelukast will have airway anti-inflammatory effects and up-regulated regulatory T cells functions in asthma. |
