In #CRSwNP, nasal fibroblasts sense TLR3 signals and, via TRIF/p38/JNK/PI3K-AKT, release IL-6, CXCL8, CCL2, and CCL11-driving eosinophil recruitment and linking innate immune activation to eosinophilic inflammation and remodeling.

In AERD, 8 weeks of high-dose aspirin (ATAD) left most mediators unchanged but increased nasal IL-27, decreased IL-5/CCL11, and showed responder vs nonresponder differences in CXCL13, IL-25, and CCL13, exploratory signals that need larger studies.
