In DN patients, the BBFFAATt combination of VDR gene was more frequent than in healthy subjects (P=0,046), and the BbFFAaTt variant was more frequent than in DM2 patients (P=0,018).
When Monocytes Derived Macrophages (MDM) from DM2 patients with low VDR expression were supplemented with vitamin D, MDMs eliminate efficiently M. tuberculosis.
