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) ...

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 ...

Tree-in-bud appearance represents dilated and fluid-filled (i.e. pus, mucus, or inflammatory exudate) centrilobular bronchioles. Abnormal tree-in-bud bronchioles can be distinguished from normal centrilobular bronchioles by their more irregular appearance, lack of tapering or knobby/bulbous appearance at the tip of their branches. The tree-in-bud distribution is often patch throughout the lung. ...

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.. Because Nellcor OxiMax technology relies on cardiac signals, it mitigates signal ...

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 ...

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 (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 ...

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 ...

Your lungs have an arrangement of tubes that do oxygen in and as you relax.. The windpipe isolates into two tubes, the correct bronchus and left bronchus. These split into littler tubes called auxiliary bronchi. They split again to make littler tubes called bronchioles. The bronchioles have little air sacs toward the end called alveoli.. Noticeable all around sacs, oxygen goes into your circulatory system from the air took in. Your circulatory system conveys oxygen to every one of the cells in your body. In the meantime carbon dioxide goes from your circulatory system into the air sacs. This waste gas is expelled from the body as you inhale out.. ...

Asthma is a chronic disease of the lungs that affects the airways and your breathing. It involves the bronchi and the bronchioles, the tubes that carry air through the lungs.

Bronchospasm is the condition in which smooth muscles of the bronchi are constricted causing narrowing of airway. In short it is caused due to construction of bronchioles and bronchi. It happens when there is any inflammation on the path of respiratory system and this condition occurs when there is excess secretion of mucus inside the […]

This study demonstrates that B6 mice can be productively infected by SARS-CoV in the bronchial and bronchiolar epithelium of the respiratory tract, and that virus is rapidly cleared through a mechanism independent of NK cells, NK-T cells, and T and B lymphocytes. Virus is able to spread to the brain at late time points when it has already been cleared by the lung, and may spread to multiple other organs. SARS-CoV induces dramatic up-regulation of a subset of inflammatory chemokines and the chemokine receptor CXCR3, but interestingly this occurs without detectable expression of classic proinflammatory and immunoregulatory cytokines and without evoking marked leukocyte infiltration of the lung. Overall, infected B6 mice do not develop overt disease, but their weight gain is slowed relative to mock-infected controls.. The work confirms our previously published finding that BALB/c mice can be productively and transiently infected in the terminal bronchioles. The susceptibility of the two strains to ...

In adult mice paracetamol in hepatotoxic doses can deplete the lung of GSH8,9 and cause necrosis of the bronchiolar epithelium.7,25,26 Clara cells are particularly vulnerable as in situ activation of paracetamol by cytochrome P450 occurs with production of the toxic metabolite.25,26 Paracetamol crosses the placenta27 and can be oxidised by fetal liver to generate this metabolite.28 We suggest that heavy exposure in utero may cause oxidative damage to the bronchiolar epithelium and especially to its progenitor cell, the Clara cell, in the developing fetal lung. We speculate that this could programme the epithelial-mesenchymal-trophic unit which is involved in lung development and is thought to become reactivated29 or to persist30 in asthma, leading to BHR and persistent wheezing postnatally. The lack of an association with eczema would suggest that the relation between prenatal paracetamol exposure and wheezing is not mediated through an effect on atopy. Unexpectedly, the risk of childhood ...

Humidifier disinfectant (HD) damage was terrible chemical damage caused by household goods that happened in only South Korea, but still very little is known in HD damage. Up to now, previous research tried to focus on interstitial fibrosis on terminal bronchioles and alveoli because it is a specific finding, compared with other diseases. To figure out whole effects from HDs, much epidemiologic and toxicologic research is underway. HDs were shown to give rise to typical toxicologic effects on various target organs, such as skin, conjunctiva, naval mucosa, bronchial mucosa, alveoli and so on, which shared common toxicological responses. On a specific target, specific toxicologic effects existed. Diverse diseases along exposure pathways can occur at the same time with a common toxicologic mechanism and cause of HDs, which can be called as HD syndrome. To gain stronger scientific evidence about it, further epidemiological and toxicological studies should be applied ...

The broad interest of the Kim Lab is to characterize the biology of stem cells in normal lung and lung cancer. Numerous lung diseases such as cystic fibrosis or chronic obstructive pulmonary disease involve injured or depleted bronchiolar or alveolar epithelium. Bronchiolar and alveolar cells are also affected in adenocarcinoma, the most common form of lung cancer. It is likely that lung stem cells are critically affected in patients with these devastating diseases. Our long-term goal is to elucidate the role of stem cells in lung homeostasis as a prerequisite to the development of therapeutic strategies that can be used to prevent or attenuate lung disease.. Please see our website for more information ...

The alveolus is a small, balloon like sac at the end of the small air passages in the lungs (the bronchiole).

The season finale of Doctor Who, Hell Bent, concluded the three part story which began with the death of Clara Oswald in Face the Raven. It turned out that the ending of last weeks episode, Heaven Sent, contained some misdirection about where the finale was going. While the Doctor did return to Gallifrey, this was not at all what the episode was really about.. The Doctor returned to Gallifrey as a war hero, and used this return to save Clara. While the leaders on Gallifrey were concerned with the identity of the Hybrid, it turned out that the Doctor did not really know the answer. His priority was in saving Clara.. Face the Raven appeared to end with the Doctor allowing Clara to die as there was way to prevent her death. Now he was willing to break all the rules and risk the fracturing of time to save her. Clara was pulled out of time just before the moment of her death, in between heartbeats and lacking a pulse, not really living. She was informed of her condition by a general on Gallifrey: ...
