Randomized trial shows IL-13 enhances eotaxin production in fibroblasts, suggesting a role in eosinophilic inflammation.

The research aims to determine if Cysteinyl leukotrienes (CysLTs) enhance eosinophilic inflammation via eotaxin production by lung fibroblasts.
Investigated eotaxin production in human fetal lung fibroblasts (HFL-1) under IL-13 and LTC(4) treatment.
Measured CysLT1R expression using quantitative real-time PCR and flow cytometry after IL-13 stimulation.
Used CysLT1R antagonists pranlukast and montelukast to assess their effect on eotaxin production.
IL-13 significantly up-regulated CysLT1R mRNA and protein expression in HFL-1 after 24 h (p<0.05).
LTC(4) alone had no effect, but with IL-13, eotaxin production was increased (specific data not provided).
Use of CysLT1R antagonists abolished the synergistic effect of LTC(4) and IL-13 on eotaxin production.

Chibana et al. (2003) studied this question.
