In vitro interleukin-1 production by different dialysis membranes.
This study investigates the Il-1 production in vitro by normal peripheral blood monocytes or non-T cells following contact with different dialysis membranes (cuprophan, polysulphone, polymethylmethacrylate and polyacrylonitrile), in the presence or absence of lipopolysaccharide. The results of this study show that the physical contact between dialysis membranes and Il-1 producing cells is not by itself able to induce abundant Il-1 production unless exogenous lipopolysaccharide is added. A modest Il-1 production, however, could be observed with synthetic membranes (polysulphone and polyacrylonitrile), but not with cellulose membranes (cuprophan). Used membranes are completely ineffective as a trigger of Il-1 synthesis.
