Effect of macrophage migration inhibitory factor (MIF) gene variants and MIF serum concentrations on the risk of type 2 diabetes: results from the MONICA/KORA Augsburg Case–Cohort Study, 1984–2002

Abstract
Macrophage migration inhibitory factor (MIF) is a central mediator of innate immunity. Our aim was to investigate the triangular association between MIF genotypes, circulating MIF concentrations and incident type 2 diabetes, and to use a Mendelian randomisation approach to assess the causal role of MIF.
