Pembrolizumab in soft-tissue sarcomas with tertiary lymphoid structures: a phase 2 PEMBROSARC trial cohort - Nature Medicine

In a trial of patients with soft-tissue sarcomas, clinical outcome measures following anti-PD-1 treatment were better in a cohort prospectively selected for the presence of intratumoral tertiary lymphoid structures than in other cohorts where most patients lacked these structures.

Blocking PD-L1–PD-1 improves senescence surveillance and ageing phenotypes - Nature

PD-L1 expression by senescent cells renders them resistant to clearance by CD8 T cells, suggesting PD-L1 as a target for mitigating the effects of ageing.
