IL6 and chronic obstructive pulmonary disease: Interestingly, TSLP expression in moDCs from triple co-culture correlated positively with IL12p40, IL-6, and TNF-α in asthma, whereas in COPD with CHI3L1, IL12p40, IL-6, IL-8, TNF-α, and IL-1β suggesting a different pathway of immune response in asthma and COPD.
