Abstract EN
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by synovial inflammation triggered by infiltrating CD4 lymphocytes.
The positioning and activation of lymphocyte in inflamed synovial tissues are dependent on a number of factors including their chemokine receptor expression profile.
We aimed to investigate which chemokine receptors pattern correlate with serum cytokine levels and with disease activity.
Forty patients with RA (34 female and 6 male) with age range from 21 to 68 years were included.
Twenty healthy volunteers (16 female and 4 male) with matched age (range 21–48 years) were served as healthy controls (HCs).
Expression of chemokine receptors (CCR5, CX3CR1 and CCR7) together with the apoptosis-related marker (CD95) was analyzed using three-color flow cytometry analysis after gating on CD4+ peripheral blood lymphocytes.
Plasma levels of IL-6, IL-10, IL-12 and TNF-a cytokines were measured in all participants using ELISA.
Disease activity score (DAS28-CRP) system was assessed and active disease was defined as DAS28 P3.2.
Twenty-five (62.4%) patients were classified as active RA (ARA) and 15 (37.5%) patients with inactive RA (IRA).
Percentages of CD4+ lymphocytes expressing CD95 with either of CCR7 or CCR5 were significantly higher in ARA compared to IRA and HCs groups, while the expression of CX3CR1 on T-cells was found significantly lower in both CD95 and CD95+ T-cells in RA groups than HC.
Percentages of CD4+CD95+CCR7+ cells correlated positively with IL-6 (r = 0.390).
Whereas CD4+CD95+CX3CR1+ were negatively correlated with TNF-a (r = 0.261).
Correlation of CD4+CD95+CCR7+ T cell subset with disease activity and inflammatory cytokines suggests a role for this cell subset in the pathogenesis of RA.
Further investigation will be required to fully characterize this cell subset and its role in disease progression
