After co-stimulation of PBMCs with FCWAs and LPS, the production of TNF-α, IL-6, IL-10 and IL-12 was significantly higher in patients with sarcoidosis, compared to healthy subjects (1.7-fold, 2.0-fold, 2.2-fold, and 2.8-fold, respectively; all p < 0.05) (Fig. 1). Here, IL10 is linked to sarcoidosis.
