Résumé :

Recently, various proteoglycans (PGs) have been identified in the lung. The first objective of this thesis was to test the hypothesis that matrix glycosaminoglycans contribute to lung tissue viscoelasticity. Lung parenchymal strips were exposed to specific glycosaminoglycans-degradating enzymes to determine whether the mechanical properties of the tissue were affected. The degradation of heparan sulphate and chondroitin/dermatan sulphate glycosaminoglycans caused significant increases in energy dissipation and dynamic resistance relative to control strips. Hyaluronidase treatment did not alter

Résumé :

Airway remodeling in asthma includes alterations in extracellular matrix and airway smooth muscle (ASM) mass. For this study, ASM cells were obtained from rats that were challenged with ovalbumin (OVA) or saline (SAL) as control. OVA and SAL cells were seeded on plastic control (PC) or on plates coated with decorin or biglycan. OVA cell number was significantly increased versus SAL cells, for cells seeded on PC (48 h). A significant decrease in cell number was observed for both OVA and SAL cells seeded on decorin compared to PC cells (48 h). OVA cells, however, showed a more modest reduction i

Résumé :

Synthetic biomedical implants are used to replace diseased tissues and organs. Unfortunately, these implants often fail due to a lack of biocompatibility and poor integration by the recipient. This implant failure is associated with the formation of an avascular fibrous capsule and chronic inflammatory response. Additionally, small diameter vascular grafts have complications associated with surface thrombogenenicity and intimal hyperplasia. Porous polymers are often incorporated in the construction of biomedical devices because they permit tissue integration and improved biocompatibility. Whil

Résumé :

All developing embryos contain an extracellular matrix (ECM) consisting of proteins, glycoproteins, and proteoglycans. These components are important for morphogenetic processes such as cell migration, cell differentiation and cell death. The ECM of the starfish, Pisaster ochraceus, consists of three major components: A hyaline layer which coats the external surface of the embryo; a basal lamina which lines the basal surfaces of the epithelia; and a blastocoelic component which fills the embryonic cavity or blastocoel. Observations of chemically fixed asteroid embryos have revealed the hyalin

Résumé :

The asthmatic airway wall is characterized by airway remodeling, including changes in the extracellular matrix (ECM) and increased airway smooth muscle (ASM) cell mass. Further, asthmatic ASM has been shown to demonstrate enhanced contractility. Recently, we and others have shown that alterations in the matrix upon which ASM cells are grown in culture, can affect the degree of ASM cell proliferation and apoptosis. Whether changes in matrix can affect ASM cell contractility is less clear. ASM cells were isolated from the trachea of Brown Norway (BN) rats sensitized subcutaneously with ovalbumi

Résumé :

The introduction of necrophagous fly larvae (maggots) into chronic wounds for the purpose of inducing healing is an ancient practice that has recently undergone a renaissance in Western medicine. Through clinical observations, maggots are broadly recognised to debride the wound of necrotic tissue, cleanse the wound of infection and promote granulation tissue formation. Despite such recognition, little research at the biological level has been undertaken to identify the mechanisms by which maggots accomplish such feats. The dermal fibroblast is a major cellular component of granulation tissue a

Résumé :

Cardiovascular disease (CVD) is the leading cause of death in the United States. A common feature in most cardiac pathologies is the dysregulation of beta-adrenergic receptors (β-AR) and changes in the extracellular matrix (ECM). The ECM maintains strength and normal organization of cardiac tissue, while fibrosis (connective tissue scarring) is necessary for repair of damaged cardiac tissue. However, the dysregulation of the ECM leads to a number of cardiac disease pathologies. Osteopontin (OPN) is a protein with diverse biological functions in regulating the ECM such as bone resorption and ca

The purpose of this study was to examine how average fiber diameter and scaffold composition regulate cell migration. Odyssey infrared scanning evaluated this on a macroscopic level, whereas confocal microscopy focused on a more microscopic approach. The expression of proteases released into the culture med

Résumé :

The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. Inhibition is, in the adult brain, most often mediated by the neurotransmitter γ-aminobutyric acid (GABA). GABA may, however, in some cases cause excitation. GABA acts by activating GABA type A receptors (GABAARs), which are ion channels largely permeable to Cl–. The effect of

Many studies have demonstrated a connection between the fibrillin matrix and TGFβ signalling, but at present the mechanistic basis for this link is unclear. An interaction between the C-terminus of Latent TGFβ Binding Protein 1 (LTBP1) and the N-terminus of fibrillin1 has previously been identified, and may have the potential to directly link the fibrillin matrix to TGFβ signalling. To investigate the structural basis for this interaction, several multi-domain fragments of fibrillin1 and LTBP1 were expressed prokaryotically and refolded in vitro.

Résumé :

During early embryonic development, endodermal cells leave the inner cell mass (ICM) and migrate over an extracellular matrix (ECM), located on the blastocoelic side of the trophectoderm, to form a continuous layer of extraembryonic endoderm. Cell migration events depend on a family of cell surface proteins known as integrins that bind specific ECM proteins. In an effort to understand the mechanisms involved in bovine endodermal cell migration, two experiments were conducted. In the first experiment, expression of the ECM proteins fibronectin, laminin and vitronectin was evaluated by immunoflu

The mechanism of bFGF activation following vascular injury has remained elusive. bFGF is stored bound to heparan sulfate proteoglycans in the ECM of the arterial media; release from extracellular sequestration may activate bFGF and initiate SMC proliferation and migration. bFGF mobil
