Suppression of autoimmune diabetes by soluble galectin-1
Type 1 diabetes (T1D) is a T cell-mediated autoimmune disease that targets the β-cells of the pancreas. We investigated the ability of soluble galectin-1 (gal-1), an endogenous lectin that promotes T cell apoptosis, to down-regulate the T cell response that destroys the pancreatic β-cells. We demons...

Preventive gal-1 therapy shifted the composition of the insulitis into an infiltrate that did not invade the islets and that contained a significantly reduced number of Th1 cells and a higher percentage of CD4+ T cells with content of IL-4, IL-5, or IL-10. The beneficial effects of gal-1 correlated with the ability of the lectin to trigger apoptosis of the T cell subsets that cause β-cell damage while sparing naive T cells, Th2 lymphocytes, and regulatory T cells in NOD mice. Importantly, gal-1 reversed β-cell autoimmunity and hyperglycemia in NOD mice with ongoing T1D. Because gal-1 therapy did not cause major side effects or β-cell toxicity in NOD mice, the use of gal-1 to control β-cell autoimmunity represents a novel alternative for treatment of subclinical or ongoing T1D.
