Project
Our project is about celiac disease, this is a enteropathy, autoimmune affecting individuals who possess genes HLA-DQ8 or HLA-DQ2, where T cells attack the body when the gliadins and glutenins are absorbed by the small intestine, in others words, celiac patients have a permanent intolerance to gluten-containing foods.
When the gluten to come into contact
with the villi of the small intestine (enterocytes), the cells helper
(type of reporter) detected the gluten like as a toxic substance and
leave a footprint chemistry, which is followed by antibodies and
lymphocytes T and B. The first are the natural killer and an army of
these cells attack the infected cells, which could cause a carcinogen
effect, in this case the dangerous cells are the enterocytes, causing
inflammation, poor absorption, and other symptoms.
The
damage caused by the autoimmune reaction can cause
histological damage in the villi, and a biopsy of these is the
means of diagnosis of this pathology. The only current treatment is a
diet without gluten, which is expensive and difficult to follow.
This is the tip of the iceberg of
celiac disease, the symptoms as are easy to diagnose, but there are
other four ways where the symptoms are not so clear. These forms are:
- Silent Celiac Disease: Patients have no symptoms but if damage histological.
- Latent Celiac Disease: There are not symptoms and stunted villi. Individuals tend to develop the disease suddenly.
- Potential Celiac Disease: Are subjects with high genetic risk that could have the disease.
- Refractory Celiac Disease: Those patients diagnosted celiac and despite follow a diet without gluten doesn't improve and can get diseases even more serious.
The
celiac disease are associated with many diseases, these can also be
complications of refractory patients.
