Albuterol’s Effect on the β2-Adrenergic Receptor Enna van den Akker

Albuterol Intro One in twelve Americans suffer from asthma 3.7% of Americans diagnosed with Bronchitis in the past year. Used to increase lung function Medicine for asthma and bronchitis Ligand for a β2-adrenergic Receptor Results in smooth muscle relaxation and bronchodilation

With Albuterol Albuterol G-Protein β2-Adrenergic Receptor Adenylyl Cyclase GDP cAMP Ca2+ ATP GTP Protein Kinase A Myosin Light chain Phosphatase Ca2+ Ca2+ Myosin Light chain Kinase K P Calcium Channel Calcium Activated Potassium Channel

Without Albuterol G-Protein β2-Adrenergic Receptor Adenylyl Cyclase GDP cAMP Ca2+ ATP GTP Protein Kinase A Myosin Light chain Phosphatase Ca2+ Ca2+ Myosin Light chain Kinase K Calcium Channel Calcium Activated Potassium Channel

Conclusion Causes of bronchodilation and smooth muscle relaxation Decreased cellular concentration of calcium Opening of potassium channels Inactivation of myosin light chain kinase
