Figure 11From: Differential expression of chemokine receptors on peripheral blood B cells from patients with rheumatoid arthritis and systemic lupus erythematosusChemokine receptor expression and B cell migration. Peripheral blood mononuclear cells were tested in a transmigration assay. A cytometric analysis showed CXCR3 (upper row) and CXCR4 (lower row) expression on CD19+ B cells before analysis (control), after 90 min incubation in medium without chemokines (input) and after migration towards the chemokines CXCL10 (upper row) or CXCL12 (lower row) respectively (migrated).Back to article page
