Activation markers expressed by γδT cells and disease activity. Analysis for the proportion of CD69-expressing Vδ1 cells (a) and Vδ2 cells (b) cells among healthy controls (left panels), patients with RA (middle panels) and patients with AS (right panels). Percentages of CD69-positive cells are compared between non-pregnant (np) age-matched women and women studied at the third trimester (3T) and postpartum (pp). Data were analyzed for correlation between CD69-expressing Vδ1 cells (c) and Vδ2 cells (d) and the disease activity scores in pregnant (third trimester), postpartum and non-pregnant patients with RA (left panels) and AS (right panels). Disease activity in RA patients was measured using Disease Activity Score in 28 joints and C-reactive peptide (DAS28-CRP) (a) and in AS patients using Ankylosing Spondylitis Disease Activity Score and C-reactive peptide (ASDAS-CRP) (b)
