Viral infections have been proposed to elicit pathological processes leading to
the initiation of T helper 1 (T(H)1) immunity against dietary gluten and celiac
disease (CeD). To test this hypothesis and gain insights into mechanisms
underlying virus-induced loss of tolerance to dietary antigens, we developed a
viral infection model that makes use of two reovirus strains that infect the
intestine but differ in their immunopathological outcomes. Reovirus is an
avirulent pathogen that elicits protective immunity, but we discovered that it
can nonetheless disrupt intestinal immune homeostasis at inductive and effector
sites of oral tolerance by suppressing peripheral regulatory T cell (pT(reg))
conversion and promoting T(H)1 immunity to dietary antigen. Initiation of T(H)1
immunity to dietary antigen was dependent on interferon regulatory factor 1 and
dissociated from suppression of pT(reg) conversion, which was mediated by type-1
interferon. Last, our study in humans supports a role for infection with
reovirus, a seemingly innocuous virus, in triggering the development of CeD.
