1. Endothelin receptor changes during inflammation in the lung
Sammanfattning : Endothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases.

2. Modulation of the Progenitor Cell and Homeostatic Capacities of Müller Glia Cells in Retina : Focus on α2-Adrenergic and Endothelin Receptor Signaling Systems
Sammanfattning : Müller cells are major glial cells in the retina and have a broad range of functions that are vital for the retinal neurons. During retinal injury gliotic response either leads to Müller cell dedifferentiation and formation of a retinal progenitor or to maintenance of mature Müller cell functions. LÄS MER
3. Importance of MAPK and PKC in cerebrovascular endothelin receptor changes
Sammanfattning : Endothelin is a vasoactive peptide that exerts its effect through two receptors; the endothelin type A (ETA) and type B (ETB) receptor. The contractile ETA receptor is localized on smooth muscle cells in the vascular wall, while the ETB receptors are mainly situated on endothelial cells, mediating vasodilatation. LÄS MER
4. Altered expression of contractile endothelin receptors in the vascular bed
Sammanfattning : This thesis aims at characterizing the endothelin (ET) receptors in different vascular beds of man and rat. The ET-A receptor was shown to be the only contractile ET receptor present in all vascular regions, with the exception of the rat mesenteric vein where a weak ET-B receptor-mediated contraction was seen.

5. Endothelin and endothelin receptors in human pregnancy and delivery
Sammanfattning : Background: Endothelin-1 (ET-1) is a 21-amino acid peptide, first described by Yanagisawa et al in 1988. It is one of the most potent constrictors of smooth muscle cells identified to date. LÄS MER
