MBL2 and diabetes mellitus: Mannose-binding lectin (MBL) can trigger downstream inflammation and complement pathways, and it has been experimentally proven that after correcting for these factors, MBL is strongly correlated with type 2 (OR = 7.55; 95% CI = 3.44 − 19.04) and type 1 (OR = 6.99; 95% CI = 2.83 − 17.15) diabetes.
