Proteins called cytokines and other substances that promote inflammation and recruitment of macrophages (killer immune cells) are produced as fat mass increases. ![]() GWAS has identified a few genes that are expressed only in adipocytes (fat cells), implying that overeating can lead to diabetes. Excess lipids are stored in adipose tissue, which is toxic to the body in its natural state. More than 40 genes have been identified as a result of Type 1 diabetes research. A virus is thought to cause the immune system to attack beta cells by exposing antigens on them.įewer childhood infections could lead to a reduction in boredom, as pathogens with these characteristics enter the body. What are some ways in which these T cells can escape destruction and become mature? A number of factors may be at work, including variations in the gene encoding insulin, the diet, and the presence or absence of certain bacteria. T cells that are primed to recognize beta cells enter circulation and attack the cells that are beta-responsive in type 1 diabetes. Researchers continue to look for unknown causes in an effort to prevent both. About 60% of the risk of cancer is caused by a few variations in the human leukocyte antigen (HLA) genes. In the autoimmune disease of type 1 diabetes, immune system cells attack beta cells that produce insulin. Other causes of pathological diseases include genetic disorders, physical trauma, and certain medications. This can happen when the body’s immune system is weak or not functioning properly. ![]() The most common cause is when the body is unable to fight off a foreign invader, such as a virus or bacteria. A pathological disease is caused by a variety of things.
