IL13 and asthma: We observed no difference in the release of TNFα, IL-1β, IL-6, IL-10, IL-2, or IL-13 between the control group and either Groups A or B. For IL-8, subjects from Group B, with uncontrolled asthma, had 37% (β = -0.47, e-0.47= 0.63, p = 0.01) lower responses (geometric mean) to TRPM stimulation than the control group, without asthma.
