Abstract:
Celiac disease (CeD) is an autoimmune disease that is tightly associated with human leukocytes antigen DQ2 and DQ8, such that the absence of DQ2 and/or DQ8 will definitively rule out a diagnosis of CeD. DQ2 and DQ8 drive which gliadin peptides will be immunogenic, and the risk for developing CeD is dependent upon the suballeles of DQ2 and DQ8. The key immune cells in the pathogenesis of CeD are T cells, antigen presenting cells (APCs), B cells (APCs as well), and epithelial cells. The roles of γδ T cells, mast cells, and eosinophils have been the focus of recent publications.

In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
