Table 2 Expansion index of γδ T cells and Vδ2 T cells in healthy subjects and melanoma patients

From: Circulating γδ T cells in young/adult and old patients with cutaneous primary melanoma

  Expansion Indexa
Donors γδ T cells Vδ2 T cells
Healthy   
Young/adult 13.1 ± 8.8b 7.1 ± 4.5
Old 4.6 ± 3.5* 3.1 ± 2.0*
Melanoma   
Young/adult 3.8 ± 2.6* 4.6 ± 0.2*
Old 2.0 ± 1.8* 0.9 ± 0.4*
  1. a The expansion index was calculated by dividing the absolute number of γδ T cells in stimulated cultures by the absolute number of γδ T cells before culture.
  2. bData are expressed as mean ± S.D.
  3. *p at least <0.05 versus young/adult healthy subjects
