1. 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
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.

3. Study of the Proliferation, Function and Death of Insulin-Producing Beta-Cells in vitro: Role of the Transcription Factor ZBED6
Sammanfattning : A thorough understanding of beta-cell proliferation, function, death and regeneration under normal condition as well as in the progression of diabetes is crucial to the conquest of this disease. The work presented in this thesis aimed to investigate the expression and role of a novel transcription factor, Zinc finger BED domain-containing protein 6 (ZBED6), in beta-cells. LÄS MER
4. Mechanisms of transcriptional and post-transcriptional control of gene expression in the pancreatic ß-cell

5. In vitro Studies of β-cell Death and Survival. Modulation by Adenoviral Vectors and Bcl-2 Overexpression
Sammanfattning : Type 1 diabetes is a multifactorial disease resulting from the selective destruction of insulin-producing β-cells within the pancreatic islets of Langerhans. The mechanisms of β-cell death are not fully understood but cytokines are important mediators of this process. LÄS MER
