Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Methoxyluteolin inhibits release of pro-inflammatory mediators from mast cells and decreases gene expression and release of TNF, VEGF and IL-8/CXCL8. The product also significantly inhibits IL-33 stimulated expression and release of CCL5 and CCL2. Methoxyluteolin pretreatment of LAD2 mast cells decreases gene expression of TNF, CXCL8 and VEGF in response to neurotensin or substance P via mTOR activation.
