Staphylococcus aureus enterotoxin B regulates prostaglandin E-2 synthesis, growth, and migration in nasal tissue fibroblasts [PDF]

, 2008
Background. Superantigens and eicosanoids are important amplifiers and regulators of inflammation in airway diseases. We therefore studied the possible influence of Staphylococcus aureus enterotoxin B ( SEB) on the cyclooxygenase ( COX) pathway and basic

Nasal Polyposis: Insights in Epithelial-Mesenchymal Transition and Differentiation of Polyp Mesenchymal Stem Cells

International Journal of Molecular Sciences, 2020
Chronic rhinosinusitis is a common inflammatory disease of paranasal sinuses, which causes rhinorrhea, nasal congestion, and hyposmia. The genetic predisposition or the exposure to irritants can sustain the inflammatory response and the development of ...

Staphylococcus aureus controls interleukin-5 release in upper airway inflammation [PDF]

, 2018
Staphylococcus aureus is a frequent colonizer of the upper airways in chronic rhinosinusitis with nasal polyps, but also resides intramucosally, it has been shown that secreted staphylococcal proteins such as enterotoxins and serine proteases induce the ...

Antimicrobial and Defense Proteins in Chronic Rhinosinusitis with Nasal Polyps

Medicina, 2023
Background and Objectives: Chronic rhinosinusitis with nasal polyps (CRSwNP) presently remains a difficult disease to manage. Antimicrobial and defense proteins are important factors that could help characterize the role of microorganisms in CRSwNP ...

Immunological profiling of key inflammatory drivers of nasal polyp formation and growth in chronic rhinosinusitis.

Rhinology, 2019
BACKGROUND Chronic rhinosinusitis (CRS) is a chronic inflammatory condition of the upper airways, often associated with the formation of nasal polyps (CRSwNP). It is well established that macroscopically normal (non-polypoidal) sinonasal mucosa in CRSwNP

Nasal cytology as a reliable non-invasive procedure to phenotype patients with type 2 chronic rhinosinusitis with nasal polyps

World Allergy Organization Journal, 2022
Background: The identification of type-2 inflammation in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) acquires a crucial role in the endotypization needed for selecting patients for biological drugs targeting type-2 inflammation: to ...

Predictive significance of Charcot-Leyden Crystal mRNA levels in nasal brushing for nasal polyp recurrence.

Rhinology, 2019
BACKGROUND Tissue eosinophils have been shown to be associated with polyp recurrence in chronic rhinosinusitis with nasal polyps (CRSwNP). We addressed whether the mRNA levels of Charcot-Leyden Crystal (CLC) in nasal brushing samples, a molecule mainly ...
