Table 3 Basal expression of surface markers in PBMCs of patients with RA according to CD154 genotype

From: Association of the microsatellite in the 3' untranslated region of the CD154 gene with rheumatoid arthritis in females from a Spanish cohort: a case-control study

Surface markers 24CAs (n = 13) Non-24CAs (n = 15) P
CD16/CD56a 16.07 ± 10.78 12.38 ± 10.24 n.s.
CD19a 6.42 ± 3.12 4.17 ± 3.01 0.018
CD3/CD8a 17.24 ± 7.66 22.37 ± 6.67 n.s.
CD3/CD4a 44.40 ± 14.79 41.22 ± 13.11 n.s.
CD4/CD69b 14.09 ± 19.02 7.48 ± 10.25 n.s.
CD4/CD25b 59.59 ± 18.04 41.19 ± 22.84 0.036
CD4/CD154b 4.28 ± 3.81 8.12 ± 5.73 0.033
  1. Results are means ± SD for cells expressing the indicated surface markers, quantified by flow cytometry. Differences were evaluated by the Mann–Whitney U test. n, number of samples analyzed; n.s., non significant; PBMCs, peripheral blood mononuclear cells. aReferred to total lymphocytes; breferred to total CD4+ lymphocytes.
