Persistence of SARS-CoV-2 Antigens in the Nasal Mucosa of Eight Patients with Inflammatory Rhinopathy for over 80 Days following Mild COVID-19 Diagnosis

Viruses, 2023
The nasal mucosa is the main gateway for entry, replication and elimination of the SARS-CoV-2 virus, the pathogen that causes severe acute respiratory syndrome (COVID-19).

Nasal Lipopolysaccharide Challenge and Cytokine Measurement Reflects Innate Mucosal Immune Responsiveness [PDF]

, 2015
BackgroundPractical methods of monitoring innate immune mucosal responsiveness are lacking. Lipopolysaccharide (LPS) is a component of the cell wall of Gram negative bacteria and a potent activator of Toll-like receptor (TLR)-4.

Neuroregulation of Human Nasal Mucosa [PDF]

Annals of the New York Academy of Sciences, 2009
Multiple subsets of nociceptive, parasympathetic, and sympathetic nerves innervate human nasal mucosa. These play carefully coordinated roles in regulating glandular, vascular, and other processes. These functions are vital for cleaning and humidifying ambient air before it is inhaled into the lungs.

Symbiotic microbiome Staphylococcus aureus from human nasal mucus modulates IL-33-mediated type 2 immune responses in allergic nasal mucosa

BMC Microbiology, 2020
Background The host-microbial commensalism can shape the innate immune responses in respiratory mucosa and nasal microbiome also modulates front-line immune mechanism in the nasal mucosa.

Fibrinolytic components in nasal mucosa and nasal secretion [PDF]

Histochemistry and Cell Biology, 1998
We evaluated a possible role for fibrinolytic components in nasal secretion by tissue localization with immunohistochemical techniques and by measuring their antigen concentrations in nasal discharge by means of ELISA and fibrin autography. Nasal mucosa was obtained surgically from the inferior turbinate.

Glycolytic reprogramming is involved in tissue remodeling on chronic rhinosinusitis

PLoS ONE, 2023
Background Glycolytic reprogramming is a key feature of chronic inflammatory disease. Extracellular matrix (ECM) produced by myofibroblasts plays an important role in tissue remodeling of nasal mucosa in chronic rhinosinusitis (CRS).

Characteristics of nasal-associated lymphoid tissue (NALT) and nasal absorption capacity in chicken. [PDF]

PLoS ONE, 2013
As the main mucosal immune inductive site of nasal cavity, nasal-associated lymphoid tissue (NALT) plays an important role in both antigen recognition and immune activation after intranasal immunization.

Development of a nasal mucosa-removal model for evaluating cell therapy

Regenerative Therapy, 2021
Introduction: Endoscopic sinus surgery is an effective surgical procedure for treating chronic sinusitis; however, extensive exposure of the bone in the nasal cavity can result in permanent disability postoperatively.

Mechanism of TCONS_00147848 regulating apoptosis of nasal mucosa cells and alleviating allergic rhinitis through FOSL2-mediated JAK/STAT3 signaling pathway

Scientific Reports, 2021
This study was conducted to explore the roles and related mechanisms of lncRNA-TCONS_00147848 (TCONS_00147848) in nasal mucosa cell apoptosis and allergic rhinitis (AR).
