Abstract

In the present study we evaluated in vitro immunoglobulin production from IgAD individuals and healthy controls. Peripheral blood mononuclear cells (PBMC) from IgAD and controls were cultured with anti-CD40 MoAb presented on a CDw32-transfected fibroblast cell line (CD40 system) in the presence of IL-10, IL-2, IL-4, transforming growth factor-beta (TGF-β) alone as well as of IL-10 in combination with each of the other three cytokines. Only IL- 10 added alone induced significant changes in baseline immunoglobulin production; marked increases in median supernatant levels of all three isotypes were observed in both groups. The most striking finding of this study was the synergizing effect of IL-4 on IgA production in the IgAD group when added with IL-10; median IgA supernatant level increased to a value superimposable on that found in the normal controls which remained about the same as when stimulated with IL-10 alone. The synergic effect of IL-4 and IL-10 was specific to the IgA isotype.
