1. The Tyrosine Kinase GTK : Signal Transduction and Biological Function
Sammanfattning : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

2. Investigations of Strategies to Counteract Proinflammatory Cytokines in Experimental Type 1 Diabetes
Sammanfattning : Type 1 diabetes (T1D) is a chronic autoimmune disease targeted against the pancreatic β-cells. Proinflammatory cytokines are considered to play a major role in the destruction of the insulin-producing β-cells. This thesis studied strategies to counteract proinflammatory cytokines in experimental T1D. LÄS MER
3. MEKK-1 and NF-κB Signaling in Pancreatic Islet Cell Death
Sammanfattning : Type 1 diabetes is an autoimmune disease resulting in the selective destruction of the insulin producing β-cells in the pancreas. Pro-inflammatory cytokines and the free radical nitric oxide (NO) have been implicated in mediating the destruction of β-cells, possibly through activation of the mitogen activated protein kinases (MAPKs) JNK, ERK and p38.

4. Role of Inducible Nitric Oxide Synthase and Melatonin in Regulation of β-cell Sensitivity to Cytokines
Sammanfattning : The mechanisms of β-cell destruction leading to type 1 diabetes are complex and not yet fully understood, but infiltration of the islets of Langerhans by autoreactive immune cells is believed to be important. Activated macrophages and T-cells may then secrete cytokines and free radicals, which could selectively damage the β-cells. LÄS MER
5. Experimental Studies Aiming to Prevent Type 1 Diabetes Mellitus
Sammanfattning : Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which T-cells and macrophages invade the islets of Langerhans and selectively destroy the insulin producing β-cells, either directly or through the secretion of e.g. cytokines and nitric oxide (NO). This thesis has studied possible strategies to prevent T1DM. LÄS MER
