I am a scientist, businessman, author, and philanthropist. For nearly two decades, I was a professor at Harvard Medical School and Harvard School of Public Health where I founded two academic research departments, the Division of Biochemical Pharmacology and the Division of Human Retrovirology.
I discussed a cancer advance called PD-1 checkpoint inhibitors which has proven effective yet imperfect against several tumors. The technology blocks a molecule widely found on white blood T cells. Yet, there is another way to achieve this effect. Normally, this structure interacts with a binding partner, just as a hand fits in a glove. Noting this, inhibitors can intercept the molecule or
When checkpoint proteins bind to their partner receptors on cancer and other immune cells, they silence the T cells, stopping them from attacking threats. This mechanism plays an important role in maintaining immune balance. The proteins safeguard the body against overactive immune responses which could harm healthy tissues, as seen with several autoimmune diseases. However, cancer cells also co-opt this mechanism for their own purposes.
PD-L1 inhibitors disrupt the same immune mechanism as PD-1 inhibitors. They prevent PD-L1 proteins from binding to PD-1 on T cells. As illustrated in Figure 1, blocking either one of these checkpoints achieves the same goal. PD-1 can also bind to another receptor, PD-L2, but its therapeutic potential is still under investigation.Inhibitors can block PD-1, a checkpoint protein found extensively on T cells, or its partner receptor on cancer and other immune cells called PD-L1., by EMD Serano.
Notably, the FDA has yet to approve any therapies that simultaneously target the PD-1 and PD-L1 axis. This is an activefor the field, although less popular than efforts to improve inhibitor synergy with other cancer treatments. A dual blockade could comprehensively address the PD-1/PD-L1 immune axis, enhance antitumor immunity and improve patient outcomes.
