Gordon J. Freeman

Gordon Freeman is a discoverer of PD-L1 (B7-H1) and its interaction with PD-1, providing the molecular basis for anti-PD-1/PD-L1 cancer immunotherapy. His foundational work revealed how tumors exploit the PD-1/PD-L1 pathway to evade immunity and established the rationale for checkpoint blockade therapy. Freeman continues to identify novel immune regulatory pathways as potential therapeutic targets.

Gordon Freeman是PD-L1（B7-H1）及其与PD-1相互作用的发现者，为抗PD-1/PD-L1癌症免疫治疗提供了分子基础。他的基础性工作揭示了肿瘤如何利用PD-1/PD-L1通路逃避免疫，并确立了检查点阻断治疗的原理。Freeman继续识别新的免疫调控通路作为潜在的治疗靶点。
