Fig. 4From: Anti-citrullinated protein antibodies contribute to platelet activation in rheumatoid arthritisPlatelet phenotype correlates with disease activity. The expression of P-selectin (CD62P) was determined on isolated platelets from patients with rheumatoid arthritis (RA) and correlated with Disease Activity Score in 44 joints (DAS44) (a), C-reactive protein (CRP) levels (b) and anti-citrullinated protein antibodies (ACPA) (c). Platelet (PLT) numbers correlated with DAS44 score (d), CRP levels (e) and ACPA levels (f). IgG immunoglobulin GBack to article page
