Immune Checkpoint PD-1 for Drug Development

In the past few years, immune checkpoints have shown a promising role in treating various diseases, including cancers. The immune checkpoint drugs are usually designed by blocking or inhibiting the signal pathways of T cells or B cells, thus achieving resistance to diseases. A wide variety of immune checkpoint molecules, such as PD-1/PD-L1, are potential immune targets for the body's immune regulation. Novel drugs targeting the PD-1/PD-L1 pathway have been widely developed.
