Dendritic Cells in Food Allergy, Treatment, and Tolerance

Food allergy is a growing problem with limited treatment options. It is important to understand the mechanisms of food tolerance and allergy to promote the development of directed therapies. Dendritic cells (DCs) are specialized antigen-presenting cells (APCs) that prime adaptive immune responses, such as those involved in the development of oral tolerance and food allergies. The DC subsets in the gut and skin are defined by their surface markers and function. The default response to an ingested innocuous antigen is oral tolerance, which requires either gut DCs or a subset of newly identified RORγt
