Research tools to investigate the role of PD-1 in the mouse

Congratulations to Distinguished Professor Tasuku Honjo for the 2018 Nobel Prize.

The 2018 Nobel Prize in Physiology or Medicine was awarded jointly to Drs. Tasuku Honjo and James P. Allison “for their discovery of cancer therapy by inhibition of negative immune regulation” [1]. Dr. Honjo and his colleagues at Kyoto University discovered PD-1, a protein expressed on the surface of T-cells, which functions as a T-cell brake [2-5]. They also revealed antibodies against PD-1 inhibit function of the brake, leading to activation of T-cells and efficient attack to cancer cells in animal experiments including those using mutant mice which they kindly deposited to RIKEN BRC [6]. Their mouse strains useful for understandng immune system as well as the role of PD-1 have been distributed to over 200 institutions worldwide and have contributed to establish immune checkpoint therapy, which has dramatically changed the outcome of certain portion of patients with cancer.
