Yet, PBMCs from the asthma group compared to those from healthy controls showed more variability with, for the same patients, extreme (high and low) TNFα responses to the three BioPM (p < 0.01, p = 0.11 and p = 0.07 for 1 μg/ml and p = 0.13, p < 0.05 and p = 0.12 for 5 μg/ml BioPM from chicken, goat and pig farms, respectively). The gene discussed is TNF; the disease is asthma.
