Objectives

Narrative objectives1

Immune checkpoint molecules (PD-1, CTLA-4) expressed by T cells function to suppress the activation of T cells themselves, playing a role in stopping the runaway activation of T cells. PD-L1, the ligand for PD-1, is also one of the immune checkpoint molecules. When a target cell (such as a cancer cell) expresses PD-L1, it binds to PD-1 on the T cell, thereby suppressing T cell activation (attack). Immune checkpoint inhibitors (ICIs), which are antibody preparations targeting these immune checkpoints, activate T cells. Consequently, ICIs have become used in the treatment of malignant tumors. However, ICIs can sometimes cause autoimmune disease-like side effects, termed immune-related adverse events (irAEs), which have become a significant concern. The objective of this study is to clarify the characteristics of irAE, which is expected to contribute to future countermeasures against irAE.
