1. Cyclic nucleotide signalling systems in vascular smooth muscle cells and immune system cells with special reference to phosphodiesterases PDE3 and PDE4
Sammanfattning : The cyclic nucleotide signalling systems are important in vascular smooth muscle and in the immune system, and are of interest from a pharmacological point of view. Drugs which interfere with the cyclic nucleotide levels have profound effects on heart, blood vessels and airways and have actual or potential use in several important diseases, such as heart failure, hypertension, arteriosclerosis, asthma and autoimmune diseases.

2. Functional Aspects of the Juxtaglomerular Apparatus : Control of Glomerular Filtration and Renin Release
Sammanfattning : The juxtaglomerular apparatus (JGA) is a control unit of the kidney, that regulates glomerular filtration rate (GFR) and renin release, and hence extracellular volume and blood pressure. The tubuloglomerular feedback (TGF) mechanism is a negative feedback loop that regulates GFR. LÄS MER
3. Studies in beta cells and adipocytes in the context of obesity and T2D - focusing on PDE3B, OPN and SCFAs
Sammanfattning : Type 2 diabetes (T2D) is a heterogeneous disease characterized by altered lipid parameters and elevated glucose levels, as a direct consequence of impaired insulin signaling in target tissues and reduced insulin exocytosis from pancreatic β-cells. Obesity, which dramatically increases worldwide, is associated with insulin resistance and T2D. LÄS MER
4. The Role of Phosphodiesterase 3B in the Regulation of Insulin Secretion
Sammanfattning : Pancreatic beta-cell dysfunction and insulin resistance are the two hallmarks of type 2 diabetes. An early sign of beta-cell dysfunction is impaired nutrient-induced insulin release. Several insulin secretagogues act by increasing the formation of intracellular cAMP. LÄS MER
5. Pharmacological evaluation of the NO/cGMP signalling system
Sammanfattning : Platelet activation and inhibition are tightly balanced processes, regulated by various endogenous molecules. In this regard, the endothelium plays a key role in mediating inhibition of platelets by releasing nitric oxide (NO) and cAMP-elevating prostaglandins. LÄS MER
