title: Interleukin 10 inhibits vascular permeability factor release by peripheral blood mononuclear cells in patients with lipoid nephrosis.
abstract: The effect of recombinant human interleukin 10 (IL-10) on the in vitro secretion of vascular permeability factor (VPF) of peripheral blood mononuclear cells (PBMC) was evaluated in patients with lipoid nephrosis (LN). Significantly increased spontaneous and concanavalin A (ConA) stimulated secretion of VPF was detected in PBMC cultures of LN patients with the nephrotic syndrome as compared with those of normal controls. In the present study, IL-10 inhibited the ConA-stimulated VPF secretion of PBMC in LN. A significant inhibitory effect of IL-10 was observed in cultures of PBMC from LN and IgA nephropathy patients as well as from normal persons. When both ConA and anti-IL-10 antibody were added together to the PBMC, a further increase in ConA-stimulated secretion of VPF occurred. These data suggest that IL-10 is a powerful inhibitor of the secretion of VPF in LN patients.
