Immunopharmacology Comments
Mounting evidence indicates that vanin 1 is involved in inflammation associated with diseases including systemic lupus erythematosus [13], systemic sclerosis [10] and colitis [3,9,12]. In murine models increased vanin 1 activity in the gut epithelium has been implicated in promoting tissue damage and inflammation by reducing resistance to oxidative stress [2-3,11-12]. Elevated vanin 1 expression has been detected in intestinal epithelium in tissue biopsies from ulcerative colitis and Crohn's disease patients and a gain-of-function polymorphism in VNN1 is associated with increased susceptibility to irritable bowel syndrome [8]. Based on this (and other) evidence pharmacological inhibition of vanin 1 is being explored as a novel mechanism for the treatment of inflammatory diseases [5-6].

General Comments
Vanin 1 is a GPI-anchored enzyme that involved in leukocyte homing to the thymus [1] and links metabolic disease to inflammation [4,14]. Vanin 1-catalysed production of cysteamine has been linked to increased oxidative stress in tissues resulting from decreased glutathione levels. In murine models increased vanin 1 activity in the gut epithelium has been implicated in promoting tissue damage and inflammation by reducing resistance to oxidative stress [2-3,11-12].
