Bronchioles
The small airways branching off the TERTIARY BRONCHI. Terminal bronchioles lead into several orders of respiratory bronchioles which in turn lead into alveolar ducts and then into PULMONARY ALVEOLI.
Bronchi
The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA. They include the largest two primary bronchi which branch out into secondary bronchi, and tertiary bronchi which extend into BRONCHIOLES and PULMONARY ALVEOLI.
Lung
Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.
Uteroglobin
A steroid-inducible protein that was originally identified in uterine fluid. It is a secreted homodimeric protein with identical 70-amino acid subunits that are joined in an antiparallel orientation by two disulfide bridges. A variety of activities are associated with uteroglobin including the sequestering of hydrophobic ligands and the inhibition of SECRETORY PHOSPHOLIPASE A2.
Pulmonary Alveoli

Cryptogenic Organizing Pneumonia
An interstitial lung disease of unknown etiology, occurring between 21-80 years of age. It is characterized by a dramatic onset of a "pneumonia-like" illness with cough, fever, malaise, fatigue, and weight loss. Pathological features include prominent interstitial inflammation without collagen fibrosis, diffuse fibroblastic foci, and no microscopic honeycomb change. There is excessive proliferation of granulation tissue within small airways and alveolar ducts.
Epithelial Cells
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

A member of the family of tissue inhibitor of metalloproteinases. Mutations of the gene for TIMP3 PROTEIN causes Sorsby fundus dystrophy.
Nitrogen Dioxide
Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (From Merck, 11th ed) It is a major atmospheric pollutant that is able to absorb UV light that does not reach the earth's surface.
1-(5-Isoquinolinesulfonyl)-2-Methylpiperazine

A layer of epithelium that lines the heart, blood vessels (ENDOTHELIUM, VASCULAR), lymph vessels (ENDOTHELIUM, LYMPHATIC), and the serous cavities of the body.
Cilia
Populations of thin, motile processes found covering the surface of ciliates (CILIOPHORA) or the free surface of the cells making up ciliated EPITHELIUM. Each cilium arises from a basic granule in the superficial layer of CYTOPLASM. The movement of cilia propels ciliates through the liquid in which they live. The movement of cilia on a ciliated epithelium serves to propel a surface layer of mucus or fluid. (King & Stansfield, A Dictionary of Genetics, 4th ed)
Pneumonia
Infection of the lung often accompanied by inflammation.

Microscopy, Electron
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
Phorbol 12,13-Dibutyrate
A phorbol ester found in CROTON OIL which, in addition to being a potent skin tumor promoter, is also an effective activator of calcium-activated, phospholipid-dependent protein kinase (protein kinase C). Due to its activation of this enzyme, phorbol 12,13-dibutyrate profoundly affects many different biological systems.
Serotonin
A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.

The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.
Albuterol
A short-acting beta-2 adrenergic agonist that is primarily used as a bronchodilator agent to treat ASTHMA. Albuterol is prepared as a racemic mixture of R(-) and S(+) stereoisomers. The stereospecific preparation of R(-) isomer of albuterol is referred to as levalbuterol.
Rats, Wistar
A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain.
Microscopy, Electron, Scanning
Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
In Situ Hybridization
A technique that localizes specific nucleic acid sequences within intact chromosomes, eukaryotic cells, or bacterial cells through the use of specific nucleic acid-labeled probes.
Lung Neoplasms
Tumors or cancer of the LUNG.
Animals, Newborn
Refers to animals in the period of time just after birth.

Acetylcholine
A neurotransmitter found at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system.
Dogs
The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)
Mice, Inbred C57BL
Sheep
Any of the ruminant mammals with curved horns in the genus Ovis, family Bovidae. They possess lachrymal grooves and interdigital glands, which are absent in GOATS.
Disease Models, Animal
Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases. They are used as study models for human diseases.
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Neutrophils
Granular leukocytes having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral dyes.

Type IV collagen alpha chains of the basement membrane in the rat bronchioalveolar transitional segment. (7/99)

In the present study, we have analyzed the alpha(IV) chain distribution in the subepithelial basement membrane (BM) of the rat pulmonary airway from the bronchi to alveoli. We have furthermore analyzed the alpha(IV) chain distribution in the subepithelial BM of the bronchioalveolar duct junction (BADJ) using alpha(IV) chain specific monoclonal antibodies. Our results show that the BM of the bronchial and bronchiolar epithelium contains [alpha1(IV)]2alpha2(IV) and [alpha5(IV)]2alpha6(IV) molecules and confirmed that the alveolar BM consists of [alpha1(IV)]2alpha2(IV) and alpha3(IV) alpha4(IV)alpha5(IV) molecules. There are also small regions in BADJ consisting of only [alpha1(IV)]2alpha2(IV) molecules without alpha3(IV)alpha4(IV)alpha5(IV) and [alpha5(IV)]2alpha6(IV) molecules. Moreover, the bronchioalveolar stem cells (BASCs)-primordial cells for bronchiolar Clara cells and alveolar type II (AT2) cells - lie adjacent to such small regions. These findings suggest that [alpha1(IV)]2 alpha2(IV) may be important for the BASCs to self-renew or to self-maintain themselves and that microenvironments produced by alpha(IV) chains may be important for cell differentiation.  (+info)

beta-Catenin is not necessary for maintenance or repair of the bronchiolar epithelium. (8/99)

Club cell secretory protein (CC-16) is a sensitive biomarker of airways epithelium integrity. It has gained interest as a biological marker in chronic lung diseases because of its presumed relationship to inflammation. Little is known about the association between CC-16 serum level and asthma, lung function and airway responsiveness (AR). Serum CC-16 level was determined by latex immunoassay in 1298 participants from the French Epidemiological case-control and family-based study on Genetics and Environment of Asthma (EGEA) (mean age 43 years; 49% men, 38% with asthma). Pre-bronchodilator lung function (forced expiratory volume in 1 s (FEV1 ), forced vital capacity (FVC) and FEV1 /FVC) and degree of AR, expressed as a function of the dose-response slope to methacholine test were measured. Standardized residuals CC-16 z-scores were obtained by regressing CC-16 level on the glomerular filtration rate. CC-16 z-scores were correlated with asthma, lung function and AR in participants with and without asthma.

Antibody Review - Clara Cell MarkersAntibody Review - Clara Cell Markers
Clara cells are non-mucous and non-ciliated secretory cells found in the primary bronchioles of the lungs, and were originally described by their namesake, Max Clara in 1937.. Clara cells are dome-shaped and have short microvilli. One of the main functions of Clara cells is to protect the bronchiolar epithelium. They do this by secreting a small variety of products, including Clara cell secretory protein (CCSP) and a component of the lung surfactant. They are also responsible for detoxifying harmful substances inhaled into the lungs. Clara cells accomplish this with cytochrome P450 enzymes found in their smooth endoplasmic reticulum. Clara cells also multiply and differentiate into ciliated cells to regenerate the bronchiolar epithelium.. CC10 (Clara cell secretory protein) ...

Parabronchial smooth muscle constitutes an airway epithelial stem cell niche in the mouse lung after injuryParabronchial smooth muscle constitutes an airway epithelial stem cell niche in the mouse lung after injury
article{2003590, abstract = {During lung development, parabronchial SMC (PSMC) progenitors in the distal mesenchyme secrete fibroblast growth factor 10 (Fgf10), which acts on distal epithelial progenitors to promote their proliferation. beta-catenin signaling within PSMC progenitors is essential for their maintenance, proliferation, and expression of Fgf10. Here, we report that this Wnt/Fgf10 embryonic signaling cascade is reactivated in mature PSMCs after naphthalene-induced injury to airway epithelium. Furthermore, we found that this paracrine Fgf10 action was essential for activating surviving variant Clara cells (the cells in the airway epithelium from which replacement epithelial cells originate) located at the bronchoalveolar duct junctions and adjacent to neuroendocrine bodies. After naphthalene injury, PSMCs secreted Fgf10 to activate Notch signaling and induce Snail expression in surviving variant Clara cells, which subsequently underwent a transient epithelial to mesenchymal transition ...

The principle function of the lung is to provide oxygen to the blood and in exchange rid the blood from carbon dioxide. Inhaled air passes through the trachea that branch into two bronchi, each supplying one of the two lobes of lung. In the lung, each bronchus branches into narrower bronchi that eventually terminate in bronchioles. The wall of bronchioles consist of ciliated cuboidal epithelium and a thin layer of smooth muscle. As opposed to upper parts of the respiratory tract, it lacks hyaline cartilage. The main cell types of the bronchioles are similar to the ones in the bronchi namely, basal cells, neuroendocrine cells, ciliated cells, serous cells, Clara cells and goblet cells. Goblet and ciliated cells decrease in number as one approaches the terminal bronchioles, whereas the number of Clara cells increases proportionally. The Clara cells have a secretory function and represent the main progenitor cell after bronchiolar injury. They are columnar to cuboidal in shape and project above the ...

GPRC5A is a G-protein coupled receptor expressed in lung tissue but repressed in most human lung cancers. Studies in Gprc5a-/- mice have established its role as a tumor suppressor function in this setting, but its the basis for its role have been obscure. Here we report that GPRC5A functions as a negative modulator of EGFR signaling. Mouse tracheal epithelial cells (MTEC) from Gprc5a-/- mice exhibited a relative increase in EGFR and downstream STAT3 signaling, whereas GPRC5A expression inhibited EGFR and STAT3 signaling. GPRC5A physically interacted with EGFR through its transmembrane domain, which was required for its EGRF inhibitory activity. Gprc5a-/- MTEC were much more susceptible to EGFR inhibitors than wile-type MTEC, suggesting their dependence on EGFR signaling for proliferation and survival. Dysregulated EGFR and STAT3 were identified in the normal epithelia of small and terminal bronchioles as well as tumors of Gprc5a-/- mouse lungs. Moreover, in these lungs EGFR inhibitor treatment ...

The human body requires energy to maintain life. Each organ is made up of millions of cells that perform various life support functions. All of these organs and cells have the same basic requirements. They need delivery of oxygen and fuel (such as glucose) in order to produce energy. And they need removal of unwanted energy byproducts like carbon dioxide. It is the team effort provided by the heart and lungs that provides this service to the cells. The lungs provide oxygenation of the blood and the heart pumps that oxygenated blood along with glucose and other nutrients to the cells. The heart then transports the carbon dioxide back from the cells to the lungs where it is disposed. [pic1]This cycle begins when the diaphragm contracts and generates a negative pressure inside the chest cavity that causes the lungs to expand thus drawing in outside air. This air traverses a system of tubes that begins with the trachea and ends where the terminal bronchiole connects to the alveolus or air sac. The ...

Covidien (NYSE:COV [1]) and Philips [2] (NYSE:PHG [3]) are launching another pulse oximetry product as part of a long-running partnership. Mansfield, Mass.-based Covidien said it will provide its Nellcor SpO2 pulse oximetry technology for use with the Philips IntelliVue patient monitoring platform in North America, Europe and elsewhere. The partnership between 2 of the largest companies in the medical device space dates back to 2009, according to a Covidien spokeswoman. The company does not break out how much revenue it derives from the distribution deal, as the Respiratory & Monitoring Solutions division is 1 of 5 operating units in the companys medical device segment, which brought in over $2 billion in sales [4] during the 3 months ended March 30. Covidien recently bolstered the respiratory unit with a $300 million acquisition [5] of Oridion Systems in April. That deal is expected to close this quarter..

RESPIRATORY SYSTEM - AchimRESPIRATORY SYSTEM - Achim
Here is another miracle system. Air enters your nose and passes down to that same pharynx again. But this time, the swallow mechanism is not in operation, so the air goes directly downward into the larynx, past your voice box, and into the trachea, which then divides into the two bronchi, which then lead through the bronchioles into tiny air sacs called atria. Think of two trees with their branches continually rebranching until finally they end-in grapes! That is the appearance of the bronchi, bronchioles, and atria. Tiny projections, called alveoli, protrude outward from each grape-like atrium into the lung. It all does look very much like a bunch of grapes! The plan is to exchange oxygen for carbon dioxide-as much as possible and as quickly as possible. There are over 400 million alveoli; each one is closely connected with blood and lymph vessels, nerves, and connective tissue.. That is what, on the inside, your lungs look like; From the outside, the lungs appear to be two cone-shaped organs, ...

Cells of the terminal bronchioles are particularly susceptible to the effects of inhalation of low levels of O3. One-day-old (juvenile) or 6 week old (adult) rats were exposed to 0.25 ppm O3 12 hours/day for 6 weeks. Morphometric analysis of perpendicular cross sections of terminal bronchioles demonstrated that exposure to O3 produced alterations in the surface characteristics of ciliated and non-ciliated (Clara) cells in both groups of rats. There were significant losses (20-30 percent) of the surface area contributed by cilia and the luminal surface of Clara cells was decreased by 16 percent to 25 percent. O3 exposure produced significant decreases in the number of brush cells per sq mm of terminal bronchiolar basement membrane. The results of the study indicate that the normal structure of terminal bronchiolar epithelial cells is significantly altered by inhalation of 0.25 ppm O3. No statistically significant interactions between the effects of O3 and animal age at the beginning of the ...

Lung - WikipediaLung - Wikipedia
The lungs are part of the lower respiratory tract, and accommodate the bronchial airways when they branch from the trachea. The bronchial airways terminate in alveoli, the lung parenchyma (the tissue in between), and veins, arteries, nerves, and lymphatic vessels.[3][11] The trachea and bronchi have plexuses of lymph capillaries in their mucosa and submucosa. The smaller bronchi have a single layer of lymph capillaries, and they are absent in the alveoli.[12] All of the lower respiratory tract including the trachea, bronchi, and bronchioles is lined with respiratory epithelium. This is a ciliated epithelium interspersed with goblet cells which produce mucus, and club cells with actions similar to macrophages. Incomplete tracheal rings of cartilage and smaller plates of cartilage in the bronchi, keep these airways open.[13] Bronchioles are too narrow to support cartilage and their walls are of smooth muscle, and this is largely absent in the narrower respiratory bronchioles which are mainly just ...

The lung is the main organ in the respiratory system and doesnt develop till about week 4 in the embryo. This stage of development is known as the Embryonic stage that covers the period of week 4-5 of the developing embryo. In this stage the 2 lung buds would have formed and lung lobes and the bronchopulmonary segments. The stem diverticulum will have differentiated into trachea and larynx. The Pseudoglandular stage is the period from 6 weeks to 16 weeks in the growing fetus. The events that occur in this stage include the formation of extensive airway branching of about 14 or more generations of branching resulting in terminal bronchioles. The conducting epithelium tubes are formed and are surrounded by thick mesenchyme. At 2 months all of the segmental bronchi would have formed. The distal structures at this stage are lined with cuboidal epithelium. The next stage is the Canalicular stage, from the period of week 16 to 25. The terminal bronchioles divide into two or more respiratory ...

Diffuse panbronchiolitis - WikipediaDiffuse panbronchiolitis - Wikipedia
Diffuse panbronchiolitis (DPB) is an inflammatory lung disease of unknown cause. It is a severe, progressive form of bronchiolitis, an inflammatory condition of the bronchioles (small air passages in the lungs). The term diffuse signifies that lesions appear throughout both lungs, while panbronchiolitis refers to inflammation found in all layers of the respiratory bronchioles (those involved in gas exchange). DPB causes severe inflammation and nodule-like lesions of terminal bronchioles, chronic sinusitis, and intense coughing with large amounts of sputum production. The disease is believed to occur when there is susceptibility, or a lack of immune system resistance, to DPB-causing bacteria or viruses, caused by several genes that are found predominantly in individuals of East Asian descent. The highest incidence occurs among Japanese people, followed by Koreans. DPB occurs more often in males, and usually begins around age 40. It was recognized as a distinct new disease in the early 1960s, and ...

Systems of Gas Exchange- Online Textbook Chapters - Alyvea.comSystems of Gas Exchange- Online Textbook Chapters - Alyvea.com
In the lungs, air is diverted into smaller and smaller passages, or bronchi. Air enters the lungs through the two primary (main) bronchi (singular: bronchus). Each bronchus divides into secondary bronchi, then into tertiary bronchi, which in turn divide, creating smaller and smaller diameter bronchioles as they split and spread through the lung. Like the trachea, the bronchi are made of cartilage and smooth muscle. At the bronchioles, the cartilage is replaced with elastic fibers. Bronchi are innervated by nerves of both the parasympathetic and sympathetic nervous systems that control muscle contraction (parasympathetic) or relaxation (sympathetic) in the bronchi and bronchioles, depending on the nervous systems cues. In humans, bronchioles with a diameter smaller than 0.5 mm are the respiratory bronchioles. They lack cartilage and therefore rely on inhaled air to support their shape. As the passageways decrease in diameter, the relative amount of smooth muscle increases.. The terminal ...

Patients who survive an acute lung injury are able to recover their lung function, suggesting that adult lungs regenerate to a certain extent. Depending on the cause and severity of the injury, multiple progenitor cells, including alveolar type II cells and distal airway stem cells, have been shown to drive lung tissue regeneration in mice. Now, Vaughan et al. describe another cell type involved in the repair process in mouse models lung damage from influenza virus infection or bleomycin inhalation: the rare lineage-negative epithelial progenitor (LNEP).. LNEP cells are quiescently present within normal distal mouse lung and do not express mature lineage markers, such as club cell 10 (CC10) protein and surfactant protein C (SPC). However, the authors demonstrate that these cells are activated to proliferate and migrate to damaged sites and mediate lung remodeling following major injury. Using lineage tracing approaches and cell transplantation, Vaughan et al. showed that LNEP cells, but not ...
