Abstract To further understand the role of neuro-immunological interactions in the pathogenesis of rheumatoid arthritis RA we studied the influence of sympathetic neurotransmitters on cytokine production of T cells in patients with RA. T cells were isolated from peripheral blood of RA patients or healthy donors HDs and stimulated via CD3 and CD28. Co-incubation was carried out with epinephrine or norepinephrine in concentrations ranging from 10 5 M to 10 11 M. Interferon IFN -y tumour necrosis factor TNF -a interleukin IL -4 and IL-10 were determined in the culture supernatant with enzyme-linked immunosorbent assay. In addition IFN-Y and IL-10 were .
