5 Key Takeaways

• 1

  Fibrinogen cryptokines may contribute to glucocorticoid-resistant airway hyperresponsiveness through Toll-like receptor 4 signaling.

• 2

  Fluticasone failed to suppress fungus-induced airway hyperresponsiveness in a mouse model, contrasting with its effects in an ovalbumin model.

• 3

  Low-dose LPS altered the response to fungal exposure, enhancing airway hyperresponsiveness and shifting the inflammatory phenotype.

• 4

  Cryptokines increased secretion of coagulation factors in human sinonasal epithelial cells, with fibrinogen secretion rising significantly.

• 5

  The study suggests that TLR4 ligands may contribute to persistent airway hyperresponsiveness despite glucocorticoid treatment.
