Peripheral blood leukocyte subpopulations expressed as a percentage of total leukocytes (SD) and lymphocyte subpopulations (T lymphocyte subsets and B lymphocytes) expressed as a percentage of total lymphocytes (SD) in MCI subjects (n = 48) and elderly controls (n =24).

MCI subjects Mean (SD) Elderly controls Mean (SD) P values
CD45bright/SSlow (Lymphocytes) 25.06 (9.05)* 28.87(7.97) p= 0.02
CD45dim/SShigh (Granulocytes) 67.28(9.61)* 64.07(8.23) p= 0.04
CD45bright/CD14+ (Monocytes) 7.33(2.01) 6.72 (1.86) ns
CD3 (T lymphocytes) 64.64(10.14) 68.64(8.00) p= 0.06
CD3CD4 (Helper/inducer T lymphocytes) 42.12(14.26) 48.81(9.79) p= 0.06
CD3CD8 (Suppressor/cytotoxic T lymphocytes) 24.55(17.77) 24.31(11.74) ns
CD4/CD8 ratio (Helper/Cytotoxic T lymphocytes) 2.25(1.58) 2.53(1.39) ns
CD19(B lymphocytes) 11.26(9.58) 10.26(4.60) ns
