The nasal symbiont Staphylococcus species restricts the transcription of SARS-CoV-2 entry factors in human nasal epithelium

open access: yesiScience, 2021
Summary: Emerging evidence indicates that severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) is transmitted through the human nasal mucosa via the principal entry factors angiotensin-converting enzyme 2 (ACE2) and transmembrane serine ...

Peroxisome Proliferator-Activated Receptor γ Negatively Regulates Allergic Rhinitis in Mice

open access: yesAllergology International, 2009
Background: Peroxisome proliferator-activated receptor γ (PPAR-γ) has been shown to play an important role in the control of inflammatory responses acting on macrophages, mast cells, T cells, and eosinophils.

RETRACTED ARTICLE: MicroRNA-29 mediates anti-inflammatory effects and alleviation of allergic responses and symptoms in mice with allergic rhinitis

open access: yesAllergy, Asthma & Clinical Immunology, 2021
Background To investigate the role of microRNA-29 (miR-29) in mice with allergic rhinitis (AR) and its underlying mechanism. Methods AR model was established in BALB/c mice by intraperitoneal sensitization and intranasal challenge with ovalbumin (OVA ...

Spider Angioma of the Nasal Mucosa [PDF]

open access: yesEar, Nose & Throat Journal, 2020
Spider angioma is a benign vascular lesion reminiscent of a spider’s body characterized by peculiar dilatation of end vasculature. The lesion is characterized by a central spot and extensions which radiate outward like a spider’s body. Spider angiomas may appear as a solitary or multiple lesion that arises on the skin surface of the face, neck, chest ...

Occupational Argyria of the Nasal Mucosa [PDF]

open access: yesHead and Neck Pathology, 2017
A biopsy specimen from the nasal mucosa of a 37-year-old man disclosed a subepithelial accumulation of black granules mainly running parallel to the surface in the absence of any inflammatory infiltrate. Since the mucosal pigment was negative with Perls' stain and resisted to melanin bleach, an exogenous pigmentation was suspected.

Nasal symbiont Staphylococcus epidermidis restricts the cellular entry of influenza virus into the nasal epithelium

open access: yesnpj Biofilms and Microbiomes, 2022
Our recent study presented that human nasal commensal Staphylococcus epidermidis could potentiate antiviral immunity in the nasal mucosa through interferon-related innate responses. Here, we found that human nasal commensal S.

The vasoactivity of endothelin in the nasal mucosa.

open access: yesNippon Jibiinkoka Gakkai Kaiho, 1991
Endothelin (ET), a novel endothelium-derived vasoconstrictor peptide with 21 amino acid residues, has recently been isolated from the supernatant of cultured porcine aortic endothelial cells. Several authors reported preliminary results demonstrating that ET has a potent contractile action in vascular smooth muscles, but its effect is slightly ...

Lymphocyte Differentiation in the Nasal Mucosa

open access: yesEuropean Journal of Inflammation, 2007
Few cytological studies have investigated the morphologic changes occurring during lymphocyte differentiation in the nose. The aim of the study is to investigate lymphocyte and plasma cell morphology in patients with allergic rhinitis. Nasal cytology was performed in 110 patients (61 men, 49 women) of ages ranging from 12 to 47 years (mean age, 27), 72

Nasal Delivery of High Molecular Weight Drugs

open access: yesMolecules, 2009
Nasal drug delivery may be used for either local or systemic effects. Low molecular weight drugs with are rapidly absorbed through nasal mucosa. The main reasons for this are the high permeability, fairly wide absorption area, porous and thin endothelial

Neuroregulation of Human Nasal Mucosa [PDF]

open access: yesAnnals 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.
