Purpose of reviewDendritic cells are critical in directing inflammatory versus tolerogenic responses. As the burden of allergic disease rises worldwide, increased understanding of mechanisms underlying these diseases is needed. This review highlights research demonstrating how dendritic cells influence allergic disease development, providing important mechanistic insights into current clinical management strategies as well as potential areas of focus for future development of novel therapeutic strategies.Recent findingsRecent studies continue to elucidate dendritic cell-associated pathways which can either promote or prevent allergic inflammation. Mechanisms involved include various aspects of dendritic cell activity, from antigen sampling and dendritic cell migration to complex dendritic cell interactions with other immune cells, infectious agents and allergens. A deeper understanding of these mechanisms and how dendritic cells promote tolerance provides insight into potential strategies to therapeutically target dendritic cells in the management of allergic disease.SummaryRecent discoveries illustrate crucial roles of dendritic cells as regulators of inflammatory versus tolerant cascades. Building on lessons from oncologic strategies for harnessing dendritic cells to promote antitumor responses, several novel pathways could also be targeted to promote dendritic cell-mediated tolerogenesis in the context of allergy. Additional studies are needed to further define the roles and potential effects of dendritic cells in these potential strategies to reduce allergic inflammation.
