Fondo	CD27 antigen is a ~29 kDa protein. Costimulatory immune-checkpoint receptor expressed at the surface of T-cells, NK-cells and B-cells which binds to and is activated by its ligand CD70/CD27L expressed by B-cells. The CD70-CD27 signaling pathway mediates antigen-specific T-cell activation and expansion which in turn provides immune surveillance of B-cells. Mechanistically, CD70 ligation activates the TRAF2-PTPN6 axis that subsequently inhibits LCK phosphorylation to promote phenotypic and transcriptional adaptations of T-cell memory. In addition, activation by CD70 on early progenitor cells provides a negative feedback signal to leukocyte differentiation during immune activation and thus modulates hematopoiesis. Negatively regulates the function of Th2 lymphocytes in the adipose tissue. 1. Izawa, K. et al. (2017) The Journal of experimental medicine 214, 73-89. PMID: 28011863 2. Jaeger-Ruckstuhl, CA. et al.

Flow cytometry

Untransfected cells (blue Histogram) and Transfected cells (Yellow Histogram) were stained with an anti-human CD27 monoclonal antibody at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer.
