NOS2 expression was also up-regulated in lipopolysaccharide- and interferon-γ-stimulated monocyte subsets from patients with PsA compared to healthy controls.
Results of western blotting and immunofluorescence showed that protein levels of iNOS in ghrelin- pretreated group were significantly reduced compared with LPS- or PA- treated group, while protein levels of eNOS were restored by ghrelin pretreatment.
