Previous studies show that IL-6 can lead to asthma and other lung diseases via increasing airway mucus hypersecretion.[9,10] IL-12 is a heterodimer made up of α and β subunits that are termed p35 and p40, respectively, and is characterized by production of interferon-γ that is also an important cytokine in antitumor immunity. Here, IL6 is linked to asthma.
