Annotation:

The pulmonary surfactant system includes specific proteins involved in the regulation of surfactant secretion and recycling, conversion of secreted lamellar bodies to tubular myelin, film adsorption, and stimulation of alveolar macrophages. Hydrophobic proteins are essential for the rapid physiological action of exogenous surfactants currently used in clinical practice.

Respiratory distress syndrome (RDS) is primarily due to decreased production of pulmonary surfactant, and it is associated with significant neonatal morbidity and mortality. Exogenous pulmonary surfactant therapy is currently the treatment of choice for RDS, as it demonstrates the best clinical and economic outcomes. Studies confirm the benefits of surfactant therapy to include reductions in mortality, pneumothorax, and pulmonary interstitial emphysema, as well as improvements in oxygenation and an increased rate of survival without bronchopulmonary dysplasia.

Annotation:

Pulmonary surfactant is a soap-like chemical synthesized by type II alveolar pneumocytes and is a mixture of phospholipids (predominantly dipalmitoylphosphatidylcholine), some other lipids and proteins. Its main functions include lowering the surface tension and maintaining the stability of alveoli. The first documented trial involving exogenous use of surfactants as a therapy was recorded in early 1970s using synthetically produced phospholipid mixtures once the chemical composition of surfactants was deciphered. Gradually there was a transition to the use of more natural sources. And animal

Surfactant is a complex mixture of phospholipids, mainly dipalmitoylphosphatidylcholine (DPCC) and surfactant proteins (SP); SP-A, SP-B, SP-C, and SP-D. DPCC plays a crucial role in lowering the surface tension, while SPs provide immunity against invading pathogens. SPs also enhance the activity of phospholipids, aiding in the adsorption and spread of surfactants all over the alveolar surface. Surfactant production starts as early as 24 weeks of gestation in humans and peaks at about 36-38 weeks. The generation and secretion of lung surfactants are tightly regulated processes.

As birds have tubular lungs that do not contain alveoli, avian surfactant predominantly functions to maintain airflow in tubes rather than to prevent alveolar collapse. Consequently, we have evaluated structural, biochemical, and functional parameters of avian surfactant as a model for airway surfactant in the mammalian lung. Surfactant was isolated from duck, chicken, and pig lung lavage fluid by differential centrifugation. Electron microscopy revealed a uniform surfactant layer within the air capillaries of the bird lungs, and there was no tubular myelin in purified avian surfactants. Phosp

Exogenous surfactant therapy has an established role in the management of neonatal respiratory distress syndrome (RDS). This article summarises the current evidence on surfactant therapy. The use of surfactant for the treatment or prophylaxis of neonatal RDS results in a 30% to 65% relative reduction in the risk of pneumothorax and up to a 40% relative reduction in the risk of mortality. Adverse effects, of which pulmonary haemorrhage is of most concern, are infrequent and long-term follow-up studies of treated patients are reassuring.

Type II pneumocytes, normally responsible for surfactant production and release, are insufficiently formed and differentiated in the premature infant born before 34 weeks' gestation. Without an adequate amount of pulmonary surfactant, alveolar surface tension increases, leading to collapse and decreased lung compliance. Pulmonary surfactants are naturally occurring substances made of lipids and proteins. They lower surface tension at the interface between the air in the lungs, specifically at the alveoli, and the blood in the capillaries. This review examines the relative benefits of the two m

Although vernix caseosa is known to be a natural biofilm at birth, human pulmonary surfactant commences to remove the vernix from fetal skin into the amniotic fluid at gestational week 34, i.e., well before delivery. To explain this paradox, we first produced two types of fluorescently labeled liposomes displaying morphology similar to that of pulmonary surfactant and vernix caseosa complexes. We then continuously administered these liposomes into the amniotic fluid space of pregnant rabbits.

In these studies, we compared surfactant accumulation in wild-type mice and mice in which IL-13 was overexpressed in the lung. When compared with littermate controls, transgenic animals showed alveolar type II cell hypertrophy under light and electron microscopy. Over time, their alveoli also filled with surfactant in a pulmonary alveolar proteinosis

Annotation:

The study of pulmonary surfactant, directed towards prevention and treatment of respiratory distress syndrome in preterm infants, led to the identification of novel proteins/genes that determine the synthesis, packaging, secretion, function, and catabolism of alveolar surfactant. The surfactant proteins, SP-A, SP-B, SP-C, and SP-D, and the surfactant lipid associated transporter, ABCA3, play critical roles in surfactant homeostasis. The study of their structure and function provided insight into a system that integrates the biophysical need to reduce surface tension in the alveoli and the inna

Annotation:

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease, characterized by the intraalveolar accumulation of surfactant-like lipoprotein substance. There are three forms of the disease: autoimmune (formerly known as idiopathic), secondary and congenital PAP. The disturbances of surfactant metabolism (protein-lipoid complex secreted by type II pneumocytes) play the crucial role in the development of the disease. Surfactant decreases a surface tension of alveoli and prevents its collapse at the end of the expiration and takes part in protection against infections as well. Surfactant is i

Annotation:

Reptilian lungs are potentially susceptible to fluid disturbances because they have very high pulmonary fluid filtration rates. In mammals, pulmonary surfactant protects the lung from developing alveolar edema. Reptiles also have an order of magnitude more surfactant per square centimeter of respiratory surface area compared with mammals. We investigated the role of reptilian surfactant 1) in the entry of vascularly derived fluid into the alveolar space of the isolated perfused lizard ( Pogona vitticeps) lung and 2) in the removal of accumulated fluid from the alveolar space of the isolated pe

Leakage of plasma proteins into the alveolar space may inhibit surfactant function. We compared the surface properties and the sensitivity to inhibitory proteins of different organic solvent surfactant extracts and a synthetic surfactant. Experiments were performed in the pulsating bubble surfactometer, with surfactant concentrations ranging between 0.1 and 2 mg.ml-1. Inhibition profiles towards fibrinogen, albumin and haemoglobin were obtained from calf lung surfactant extracts (CLSE), Alveofact, Curosurf and Survanta (all used in clinical, replacement studies in respiratory distress syndrome

Homeostasis of pulmonary surfactant requires metabolic clearance of surfactant forms with decreased surface activity. Rabbit pulmonary surfactant was labeled in vivo with rhodamine-labeled dipalmitoylphosphatidylethanolamine (R-DPPE), isolated, and fractionated into large- and small-aggregate subfractions by differential centrifugation. Endocytosis of large (LA)- and small (SA)-aggregate surfactant by a mouse lung epithelial cell line (MLE-12) was evaluated in vitro by epifluorescence microscopy. More SA than LA surfactant was taken up by MLE-12 cells. Endocytosis of SA and LA surfactant was i

Introduction E-cigarette (EC) and vaping use continue to remain popular amongst teenage and young adult populations, despite several reports of vaping associated lung injury. One of the first compounds that EC aerosols comes into contact within the lungs during a deep inhalation is pulmonary surfactant. Impairment of surfactant’s critical surface tension reducing activity can contribute to lung dysfunction. Currently, information on how EC aerosols impacts pulmonary surfactant remains limited. We hypothesized that exposure to EC aerosol impairs the surface tension reducing ability of surfactan

Targeted disruption of the surfactant protein (SP) D ( SP-D) gene caused a marked pulmonary lipoidosis characterized by increased alveolar lung phospholipids, demonstrating a previously unexpected role for SP-D in surfactant homeostasis. In the present study, we tested whether the local production of SP-D in the lung influenced surfactant content in SP-D-deficient [SP-D(−/−)] and SP-D wild-type [SP-D(+/+)] mice. Rat SP-D (rSP-D) was expressed under control of the human SP-C promoter, producing rSP-D, SP-D(+/+) transgenic mice. SP-D content in bronchoalveolar lavage fluid was increased 30- to 5

Background: Exogenous surfactants from natural sources help restore normal lung function in premature cases. Pulmonary-surfactant dysfunction can lead to acute lung injury and is characterized by alveolar instability, floating, and collapse. These abnormalities occur in adult respiratory distress syndrome (ARDS) and neonatal respiratory distress syndrome (NRDS). Objectives: This study aimed to identify the best source of exogenous natural surfactant and its composition. Methods: Twenty-four healthy Holstein calves were selected in three age groups in both sexes to investigate the impact of sex
