The effects of sera derived from patients suffering from chronic renal diseases (endemic Balkan nephropathy, glomerulonephritis and pyelonephritis) on T cell proliferative response was studied. It was found that these sera contained factors which affect interleukin 1 (IL-1) dependent events in T cell proliferative response. The factors prevent costimulatory effects of IL-1 on T cells but do not bind to IL-1, nor do they affect interleukin 2 (IL-2) dependent T cell proliferation. These findings indicate that immuno-suppression observed in some kidney disorders may be partially due to serum immunoinhibitory factors affecting IL-1 activity.
