AIMS: In IgA nephropathy, circulating immune complexes containing IgA1 are deposited on the glomerular mesangium, causing mesangial cell proliferation and acceleration of extracellular matrix production. The suppressive effect of jacalin, a galactose-binding lectin, on IgA production in vitro was determined. MATERIALS & METHODS: Normal human peripheral blood mononuclear cells were stimulated with plate-bound anti-CD3 and Th2 stimulation, with or without jacalin. Regulatory and effector cell subsets were determined by flow cytometry, and immunoglobulin production by ELISA. RESULTS: Jacalin increased the ratio of CD4(+)CD25(+)CD152(+) Tregs:effector T cells in peripheral blood mononuclear cell cultures 60-fold. This CD4(+)CD25(+)CD152(+) Treg increase may have inhibited Th2-stimulated IgA production by B cells. CONCLUSION: Immune tolerance induced by jacalin can suppress IgA production.
