Main Methods:

• Literature review of programmed death-1 (PD-1) research.
• Analysis of PD-1's function in immunological self-nonself discrimination.
• Discussion of historical context and future perspectives in PD-1 research.

Main Results:

• The isolation of the PD-1 molecule in the early 1990s marked a significant milestone.
• The 2018 Nobel Prize underscored the importance of PD-1 research.
• PD-1 plays a critical role in the immune system's ability to distinguish self from non-self.

Conclusions:

• The journey of programmed death-1 (PD-1) research is extensive, with significant milestones achieved.
• Further investigation is essential to fully elucidate the complex functions of PD-1.
• Understanding PD-1's role in self-nonself discrimination is crucial for advancing immunology and medicine.
