Immunodeficiency: Magnesium regulates antiviral immunity.

The article discusses the study that explores the relevance of intracellular free Mg^(2,+) on the toxicity activity of T cells and natural killer (NK) cells. It highlights the capabilities of Mg^(2,+) in controlling the expression of the activating receptor NK group 2 member D (NKG2D). It adds that the Epstein-Barr virus (EBV) has upregulated the NKG2D ligands by infecting the cells.
