Furthermore, the frequency of CD56bright NK expressing the inhibitory receptors CD96 and PD-1 was increased in STS patients (91%, IQR: 89–95, N = 12; 0.0%, IQR: 0.0–0.3, N = 11; respectively) compared with CTRL (81%, IQR: 75–89, N = 21, p = 0.04; 0.0%, IQR: 0.0–0.0, N = 11, p = 0.04; respectively). Here, CD96 is linked to telomere syndrome.
