Induction of Tolerance via the Respiratory Mucosa

International Archives of Allergy and Immunology, 1998
Immunological tolerance is defined as a state of specific non-responsiveness to a particular antigen induced by previous exposure to that same antigen. The mucosal surfaces comprise the upper and lower respiratory tracts, the gastrointestinal tract and the urogenitary tract, and are a major site of antigenic challenge. The immune system associated with

Manuka honey: Histological effect on respiratory mucosa

American Journal of Rhinology & Allergy, 2010
Background Chronic rhinosinusitis (CRS) is an inflammatory disease in which bacteria are commonly implicated often in the form of a biofilm. Manuka honey has been shown in vitro to be an effective treatment against two common CRS pathogens both in the planktonic and in the biofilm forms.

Interaction of Mycobacterium tuberculosis with human respiratory mucosa

Tuberculosis, 2002
Endobronchial infection is associated with pulmonary tuberculosis in the majority of cases. We have investigated the adherence of Mycobacterium tuberculosis to the human respiratory mucosa.Organ cultures constructed with human tissue were infected with M.

Insulin Across Respiratory Mucosae by Aerosol Delivery

Diabetes, 1971
Insulin, a protein of about 5,700 molecular weight, was delivered by aerosol inhalation to three normal volunteers and to four patients with diabetes mellitus. Direct evidence of absorption of insulin across mucosae of the respiratory tract was an increase in plasma IRI.

pH Effects on Ciliomotility and Morphology of Respiratory Mucosa

Archives of Environmental Health: An International Journal, 1977
Tracheal cilia of cows exposed, in vitro, for 20 hours to different acidities and alkalinities of sulfuric acid and sodium hydroxide, respectively, showed ciliomotility at pH values as low as 4.9, while the epithelial cells began to be expelled from the mucosa at pH 6.7, initiating a reduction of ciliary function around this pH value.

In vitro culture of equine respiratory mucosa explants

The Veterinary Journal, 2009
An in vitro model of the upper respiratory tract of the horse was developed to investigate mechanisms of respiratory diseases. Four tissues of the upper respiratory tract of three horses were collected. Explants were maintained in culture at an air-liquid interface for 96h.

Immunohistochemical localization of 3-nitrotyrosine in the nasal respiratory mucosa of patients with vasomotor rhinitis [PDF]

Acta Oto-Laryngologica, 2005
CONCLUSION: This study demonstrates that, in the nasal respiratory mucosa of patients with vasomotor rhinitis, oxidative stress following peroxynitrite formation is confined to the respiratory epithelium.

On the Defense Mechanisms of the Respiratory Mucosa Towards Infection

Acta Oto-Laryngologica, 1980
The rapid development of immunology, biochemistry and ultramicroscopy in the past few years has also drawn scientific attention to the functions of mucous membranes in their entirety.

[Mechanisms of inflammation of the respiratory mucosa].

Presse medicale (Paris, France : 1983), 2002
A UNIVERSAL UBIQUITOUS PHENOMENON: Because it involves many different species, inflammation is a universal phenomenon. It is also an ubiquitous phenomenon because several organs may be involved within a given species. In humans, where it is involved in almost all pathological conditions, inflammation reaches its highest degree of complexity. FOUR STEPS:

Studying Bacterial Adhesion to Respiratory Mucosa

2000
Adhesion to host tissues enables human pathogens to withstand host defense mechanisms such as removal by fluid flow, mucociliary clearance, and other physical processes. Adhesion is therefore an essential prerequisite for successful colonization of epithelial surfaces and is recognized as a virulence factor for bacterial, viral and fungal pathogens ...
