WebAug 6, 2013 · In people who have no issues with gluten, the proteins are absorbed. In those with gluten sensitivity, the GALT identifies gliadin as a dangerous substance and produces antibodies to attack it. In celiacs, these antibodies don't just attack the gliadin, they attack the tTG as well, which is what originally broke down the gluten into its two parts. WebJul 4, 2008 · The putative involvement of tTG in the pathogenesis of CD could be due to two distinct but interdependent pathways.
