Figure Lengend Snippet: The interventional effect of TAK-242 Blocking TLR4 on IL-29 action. (A) Transwell assay showing changes in eosinophil migration after TLR4 blockade with TAK-242; (B) ELISA of IL-5 secretion after TAK-242 intervention; (C) ELISA of IL-13 secretion after TAK-242 intervention; (D) Western blot analysis of TLR4, p-NF-κB, and p-MAPK protein expression after TAK-242 treatment. Data are presented as mean ± SD. * indicates p < 0.05.
Article Snippet: A total of 1×10 5 eosinophils were seeded in the upper chamber, while the lower chamber was filled with RPMI-1640 medium containing 10 ng/mL IL-5 (R&D Systems, 205-IL-010) as a chemoattractant.
