Peanut-specific Tr1 cells induced in vitro from allergic individuals are functionally impaired

Peanut allergy is a life threatening condition which lacks regulatory-approved treatment. T regulatory type 1 (Tr1) cells are potent suppressors of immune responses and can be induced in vivo upon repeated antigen exposure or in vitro using tolerogenic dendritic cells (DC-10). Whether or not oral immunotherapy (OIT) leads to antigen-specific Tr1 cell induction has not been established.
