Type II avleolar epithelial cells secrete pulmonary surfactant to lower the surface tension of water, which helps prevent airway collapse. Reinflation of the alveoli following exhalation is made easier by pulmonary surfactant. The surfactant reduces surface tension within all alveoli through hydrophilic and hydrophobic forces. The pulmonary arterial circulation originates from the right side of the heart. Histologically, pulmonary arteries and veins are often adjacent to bronchi and larger bronchioles. These vessels progressively divide into smaller caliber vessels and, terminally, form a network of capillaries that course through alveolar septa and function in gas Author: Ryan Jennings, Christopher Premanandan.
In , Mason and Williams developed the concept of the alveolar epithelial type II (AE2) cell as a defender of the alveolus. It is well known that AE2 cells synthesise, secrete, and recycle all components of the surfactant that regulates alveolar surface tension in mammalian lungs. AE2 cells influence extracellular surfactant transformation by regulating, for example, pH and [Ca2+] of the Cited by: Mechanisms of injury and repair in alveolar epithelial cells (AECs) are critically involved in the progression of various lung diseases including idiopathic pulmonary fibrosis (IPF).

Convincing evidence has emerged demonstrating that impairment of mitochondrial function is critically important in regulating alveolar epithelial cell (AEC) programmed cell death (apoptosis) that may contribute to aging-related lung diseases, such as idiopathic pulmonary fibrosis (IPF) and asbestosis (pulmonary fibrosis following asbestos exposure).

Lung Epithelial Biology in the Pathogenesis of Pulmonary Pulmonic alveolar epithelium book provides a one-stop resource capturing developments in lung epithelial biology related to basic physiology, pathophysiology, and links to human disease.
The book provides access to knowledge of molecular and cellular aspects of lung homeostasis and repair, Pulmonic alveolar epithelium book the molecular basis of lung epithelial intercellular communication and lung epithelial Price: $ RESIDUAL EPITHELIAL CELLS ON THE PULMONARY ALVEOLAR WALLS OF MAMMALS [Charles C Macklin] on *FREE* shipping on qualifying : Charles C Macklin.
The section on physiology relating to the pulmonary parenchyma expands upon the discussion of gas exchange at the alveolar level that is covered in Chapter 1. Additionally, the concept of compliance as the relationship between distending pressure and lung volume is reviewed, and the shifting of compliance curves in diffuse parenchymal lung disease downward and to the right is described.
Alveolar macrophages (AM) also known as dust cells are a type of white blood cells. The immune system is divided into the cellular and humoral components. Alveolar macrophages are the first line of defense against invading respiratory pathogens.

Pulmonary alveolar epithelial cells (PAEpiC) comprised of alveolar type I and type II epithelial cells, line more than 99% of the internal surface area of the lung.
Type I cells are large squamous cells whose thin cytoplasmic extensions cover >95% of the internal surface area. They contain aquaporins and exhibit the highest osmotic water.

Lloyd, Philip L. Molyneaux. Purpose. To develop a cell culture model of human alveolar epithelial cells in primary culture for the in vitro study of pulmonary absorption and transport. Methods.

AECI, together with the capillary endothelium, form the extremely thin barrier between alveolar air and blood. Alveolar macrophages have been investigated for years by approaches involving macrophage extraction from the lung by bronchoalveolar lavage, or by cell removal from lung tissue.
Since extracted macrophages are studied outside their natural milieu, there is little understanding of the extent to which alveolar macrophages interact with the epithelium, or with one another to generate Cited by: Abstract. Idiopathic pulmonary fibrosis (IPF) is characterised by repeated injury to the alveolar epithelium with loss of lung epithelial cells and abnormal tissue repair, resulting in excessive accumulation of fibroblasts and myofibroblasts, deposition of extracellular matrix components and distortion of lung architecture, eventually leading to respiratory by: The aim of the present study is to investigate the protective effect of GB on lipopolysaccharide‐induced inflammatory responses in A human pulmonary alveolar epithelial cells (HPAEpiC) in vitro.

Idiopathic pulmonary fibrosis is a progressive disease of unknown etiology characterized by a dysregulated wound healing response that leads to fatal accumulation of fibroblasts and extracellular matrix (ECM) in the lung, which compromises tissue architecture and lung function capacity.

This text brings together in a single volume, the body of knowledge that currently exists, and explores how this knowledge may be applied in the future to increase our understanding of disease and to develop new types of treatment. Alveolar epithelial cell (AEC) injury leading to cell death is involved in the process of fibrosis development during idiopathic pulmonary fibrosis (IPF).
Among regulated/programmed cell death, the excessive apoptosis of AECs has been widely implicated in IPF pathogenesis. Necroptosis is a type of regulated/programmed by: 9. Gas exchange: Alveoli Alveoli. Alveoli (singular: alveolus) are the site of gas exchange in the lung.
