The effect of donor age and cytomegalovirus (CMV) serostatus on CD8+ T cells subsets within peripheral blood.

Age (years) Group n = (M/F) CD8+ lymphocytes ± s.d. CD8+ LFA-1low (naïve) CD8 T cells ± s.d. CD8+ LFA-1hi (memory) CD8 T cells ± s.d. CD45RA+ LFA-1hi (revertant memory) CD8 T cells ± s.d.
20–40 CMV+ 8 (4/4) 788 ± 162 205 ± 43 584 ± 142 164 ± 43
CMV 18 (9/9) 711 ± 63 344 ± 44 367 ± 33 79 ± 16
40–60 CMV+ 12 (6/6) 553 ± 84 106 ± 13 448 ± 82 160 ± 37
CMV 10 (7/3) 417 ± 38 173 ± 15 243 ± 29 54 ± 7·7
60+ CMV+ 47 (12/35) 614 ± 78 70 ± 7·3 544 ± 76 181 ± 25
CMV 29 (10/19) 437 ± 40 106 ± 14 332 ± 33 73 ± 9·5

The effect of age on the CD8 T cell count is significant (P = 0·038). Age and CMV have a significant effect on naive CD8 T cell numbers (P = 1·32E-17 and 4·01E-05 respectively). CMV also has a significant effect on memory CD8 T cells and CD45RA+ memory CD8 T cells (P = 0·0025 and P = 7·37E-08) respectively. LFA, lymphocyte function-associated antigen; M/F, male/female; s.d., standard deviation.
