General Information
Biological Significance
CD103 is a member of the integrin series of adhesion molecules. This antigen defines a developmentally
important subset of T cells, namely mucosal T cells including all IEL (intraepithelial lymphocytes) and ~20%
of lamina propria T cells. Expression of CD103 is more restricted outside these mucosal organs, appearing
at lower levels on T cell subsets of the lymph node, dendritic epidermis and periphery.
