By presenting the gluten, the receptor signals to another type of immune system cell, called a Helper T-Cell. T-Cells fight disease in the body, but in celiac disease T-Cells are triggered by gluten to mistakenly attack the enterocytes. The Helper T-Cells secrete chemicals that cause three things to happen:. Additionally, scientists theorize that in response to gluten, zonulin, a molecule made by the body and linked to inflammation, may play a role in loosening the tight junctions earlier in the process.
Currently, the only treatment for celiac disease is a strict, lifelong gluten-free diet. Potential treatments for celiac disease are designed to interrupt different steps in the disease process.

Clinical Trials. Researchers now believe that nonclassic celiac disease is actually more common than the classic form.
Celiac disease often goes undiagnosed because many of its signs and symptoms are nonspecific, which means they may occur in many disorders. Most people who have one or more of these nonspecific health problems do not have celiac disease. On average, a diagnosis of celiac disease is not made until 6 to 10 years after symptoms begin. Some people have silent celiac disease , in which they have no symptoms of the disorder. However, people with silent celiac disease do have immune proteins in their blood antibodies that are common in celiac disease.
They also have inflammatory damage to their small intestine that can be detected with a biopsy. In a small number of cases, celiac disease does not improve with a gluten-free diet and progresses to a condition called refractory sprue.
Refractory sprue is characterized by chronic inflammation of the gastrointestinal tract, poor absorption of nutrients, and an increased risk of developing a type of cancer of the immune cells called T-cell lymphoma. Celiac disease is a common disorder. Its prevalence has been estimated at about 1 in people worldwide. These genes provide instructions for making proteins that play a critical role in the immune system. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders such as viruses and bacteria.
This complex, which is present on the surface of certain immune system cells, attaches to protein fragments peptides outside the cell. If the immune system recognizes the peptides as foreign such as viral or bacterial peptides , it triggers a response to attack the invading viruses or bacteria. Celiac disease is associated with an inappropriate immune response to a segment of the gluten protein called gliadin.
This inappropriate activation of the immune system causes inflammation that damages the body's organs and tissues and leads to the signs and symptoms of celiac disease. However, these variants are also found in 30 percent of the general population, and only 3 percent of individuals with the gene variants develop celiac disease.
It appears likely that other contributors, such as environmental factors and changes in other genes, also influence the development of this complex disorder. Celiac disease tends to cluster in families. Parents, siblings, or children first-degree relatives of people with celiac disease have between a 4 and 15 percent chance of developing the disorder. Doctors treat dermatitis herpetiformis with a gluten-free diet or medication, or both, to control the rash.
Consult your doctor if you have diarrhea or digestive discomfort that lasts for more than two weeks. Consult your child's doctor if your child is pale, irritable or failing to grow or has a potbelly and foul-smelling, bulky stools. Be sure to consult your doctor before trying a gluten-free diet.
If you stop or even reduce the amount of gluten you eat before you're tested for celiac disease, you can change the test results. Celiac disease tends to run in families. If someone in your family has the condition, ask your doctor if you should be tested. Also ask your doctor about testing if you or someone in your family has a risk factor for celiac disease, such as type 1 diabetes.

Your genes combined with eating foods with gluten and other factors can contribute to celiac disease, but the precise cause isn't known.
Infant-feeding practices, gastrointestinal infections and gut bacteria might contribute, as well. Sometimes celiac disease becomes active after surgery, pregnancy, childbirth, viral infection or severe emotional stress. When the body's immune system overreacts to gluten in food, the reaction damages the tiny, hairlike projections villi that line the small intestine. Villi absorb vitamins, minerals and other nutrients from the food you eat. If your villi are damaged, you can't get enough nutrients, no matter how much you eat.
Some people with celiac disease don't respond to what they consider to be a gluten-free diet.
