Similar Assertions

When eosinophils from asthma patients are exposed to allergens, they produce about 1.58 times more TGF-β1 protein compared to before exposure, which may contribute to inflammation.

94%

When airway muscle cells are grown with allergen-activated asthma eosinophils, the fluid around them has about twice as much TGF-β1 protein as when grown with healthy eosinophils.

81%

When airway muscle cells are grown with allergen-activated asthma eosinophils, the fluid around them has about 50% more TGF-β1 protein than when grown with non-activated eosinophils.

78%

Airway muscle cells grown with allergen-activated asthma eosinophils produce over 5 times more collagen I gene activity than when grown with healthy eosinophils.
