Expression of cytokines by CD4+ T cells from patients with chronic obstructive pulmonary disease‐associated pulmonary hypertension (COPD‐PH) and controls. (a) The frequency of interleukin‐17 (IL‐17) ‐secreting CD4+ T cells upon CD3/CD28 activation. (b) The amount of IL‐17 secretion by CD4+ T cells upon CD3/CD28 activation. (c) The amount of interferon‐γ (IFN‐γ), IL‐4 and transforming growth factor‐β (TGF‐β) secretion by CD4+ T cells upon CD3/CD28 activation. Unpaired t‐test with Welch's correction.
