Expression of AITR and AITR ligand in breast cancer patients.

Human activation-inducible TNF receptor (AITR) is a new member of the tumor necrosis factor family and expressed on peripheral blood mononuclear cells (PBMC) and leukocytes. Its ligand (AITRL) is expressed in endothelial cells. This study aimed to evaluate the presence and role of AITR and AITRL in patients with breast cancer.
