  1. Short donor leukocyte telomere length is associated with CD8+CD57+HLA-DR− cell abundance in humans.

    “Immune cell profiling showed that older donors with short LTL had more CD8+CD57+HLA-DR− cells.”

Relapse-free survival

downin humans1

1 study
  1. Short donor leukocyte telomere length is associated with relapse-free survival in humans (Relapse or death aHR 1.53, 95% CI 1.06–2.20).

    “worse RFS (aHR = 1.53; 95% CI, 1.06-2.20) compared with recipients of grafts from donors <40 years.”

  1. Short donor leukocyte telomere length is associated with acute leukemia relapse in humans (aHR 1.51, 95% CI 1.04–2.19).

    “had higher CIR (adjusted hazard ratio [aHR] = 1.51; 95% confidence interval [CI], 1.04-2.19)”
