  Topic  

Pathophysiology

In order to better understand the causes of Type 2 diabetes, certain fundamental studies are necessary. Many elements are presently being studied: production of insulin, method of hormonal action, signals produced by its production, chain reaction of cells when in contact with the hormone, receptors involved in the process of detection, causes of insulin insensitivity... The development of a better understanding of each of these factors may help prevent and treat Type 2 diabetes.

Prof. Eileen Gallery (biography)
English - 2005-06-18 - 27 minutes
(37 slides)

Summary :
Type 1 diabetes is associated with poor pregnancy outcomes many of which are related to abnormalities in placental function and fetal growth (1). Of importance in diabetic pregnancy is an increased and more rapid development of a disorder called “atherosis” in the maternal blood vessels of the placental bed, which is similar to atheroma in the vessels of a non-pregnant individual. Atherosis leads...

Summary :
We postulate that many of the deleterious effects of obesity in humans may involve enhanced formation of cytokines by the non-fat cells in adipose tissue. Cytokines are factors that are involved in the response to infections but also appear to promote heart disease as well as diabetes. We compared the release of cytokines by the adipose tissue of morbidly obese women with a body fat weight of 123...

Summary :
In this presentation Russell Brown discusses experimental evidence for expression of the adipokines resistin and fasting-induced adipose factor (FIAF) in non-adipose tissues, and studies providing insights into the nature of expression of these genes.

Insulin and leptin are examples of hormones from the periphery that have been found to act in the brain, affecting food intake,...

Learning objectives :
Key Discussion Points:

- The brain and pituitary gland express adipokines including resistin and fasting-induced adipose factor (FIAF);
- RNA interference is an effective tool to study adipokines;
- These brain-derived adipokines may prove to be therapeutic targets for obesity and brain development, cell signaling and angiogenesis.
