Synergistic Induction of Macrophage Inflammatory Protein-3α/CCL20 Production by Interleukin-17A and Tumor Necrosis Factor-αin Nasal Polyp Fibroblasts

World Allergy Organization Journal, 2009
Background: Accumulation of T cells and immature dendritic cells (DCs) is one of the characteristic features of nasal polyps. However, the question remains why these cells accumulate in nasal polyp tissue. Macrophage inflammatory protein-3α (MIP-3α/CCL20)

Concordant systemic and local eosinophilia relates to poorer disease control in patients with nasal polyps

World Allergy Organization Journal, 2019
Background: Eosinophilic inflammation is a major phenotype associated with poorly controlled disease in nasal polyp patients. The difference between systemic and local eosinophilia in relation to disease control is poorly understood.

Vitamin D decreases the secretion of matrix metalloproteinase-2 and matrix metalloproteinase-9 in fibroblasts derived from Taiwanese patients with chronic rhinosinusitis with nasal polyposis

Kaohsiung Journal of Medical Sciences, 2015
Vitamin D and its derivatives have modulatory effects in immunological and inflammatory responses. Such properties suggest that they might have an impact on chronic inflammatory airway diseases, including nasal polyposis.
