Fig. 2From: The elastin peptide VGVAPG increases CD4+ T-cell IL-4 production in patients with chronic obstructive pulmonary diseaseCytokine production by CD4+ T-cells isolated from COPD patients and controls. Quantification of IFN-γ, IL-4 and IL-17A production in culture supernatants of anti-CD3/CD28-stimulated CD4+ T-cells isolated from COPD patients (n = 29) and controls (n = 13) was performed by Cytometric Bead Array Analysis. Data are presented as mean ± SD. *p < 0.05Back to article page
