Free Fatty Acids and Cytokines Induce Pancreatic ß-Cell Apoptosis by Different Mechanisms (I've scrubbed the distracting reference numbers from some excerpts of the introduction and I'm also going to try to cite only the information pertinent to T2) Hypercaloric diets containing large amounts of fat, also called the Western diet, contribute to a major extent to the increasing prevalence of obesity and type 2 diabetes mellitus (T2DM). T2DM is characterized by peripheral insulin resistance, pancreatic ß-cell dysfunction, and decreased ß-cell mass associated with increased rates of ß-cell apoptosis. Elevated levels of circulating free fatty acids (FFAs) contribute to the pathogenesis of T2DM. High concentrations of FFAs lead to both impairment of insulin action and ß-cell dysfunction.  Moreover, FFAs have been shown to cause ß -cell death, mainly by apoptosis.  Of note, increased adiposity is associated not only with increa...

Elevated Concentrations of Nonesterified Fatty Acids Increase Monocyte Expression of CD11b and Adhesion to Endothelial Cells First, a layperson friendly description of Monocytes : Monocytes are a type of leukocyte or white blood cell which play a role in immune system function. Depending on a patient's level of health, monocytes make up between one and three percent of the total white blood cells in the body. They can be counted as part of a blood test, and changes in their levels can indicate changes in a patient's health. As a general rule, a low monocyte count is a good sign, and a high count indicates that a problem is present... ... Levels of monocytes in the blood tend to rise when someone has an infection, because more of these cells are needed to fight it. Monocytes can also increase in response to stress and other factors. A high monocyte count may be referred to as monocytosis, and it is typically addressed by determining why the count is so high, and addressing th...
