Description
Integrin, alpha E (ITGAE) also known as CD103 (cluster of differentiation 103) is an integrin protein that in human. ITGAE is expressed widely on intraepithelial lymphocyte (IEL) T cells (both 伪尾 T cells and 纬未 T cells) and on some peripheral regulatory T cells (Tregs). It has also been reported on lamina propria T cells. A subset of dendritic cells in the gut mucosa and mesenteric lymph nodes, known as CD103 dendritic cells, also expresses this marker.
