Dectin-1 as a therapeutic target for inflammatory bowel disease

Inflammatory bowel disease (IBD) encompasses chronic inflammatory conditions of the distal gastrointestinal tract, including Crohn's disease and ulcerative colitis. This chapter explores the potential of Dendritic cell-associated C-type lectin-1 (Dectin-1), a pattern recognition receptor, as a therapeutic target for IBD. We delve into the multifaceted roles of Dectin-1 in immune response modulation, focusing on its interactions with the gut microbiota and immune system. Key sections include an examination of intestinal dysbiosis and its impact on IBD, highlighting the critical role of fungal dysbiosis and immune responses mediated by Dectin-1. The chapter discusses the dual functions of Dectin-1 in maintaining gut homeostasis and its contribution to disease pathogenesis through interactions with the gut's fungal community. Furthermore, the genetic and molecular mechanisms underpinning Dectin-1's role in IBD susceptibility are explored, alongside its signaling pathways and their effects on immune modulation. We also present therapeutic strategies targeting Dectin-1, including innovative drug delivery systems that leverage its natural binding affinity for β-glucans, enhancing targeted delivery to inflamed tissues. The chapter underscores the potential of dietary modulation of Dectin-1 pathways to restore gut microbiota balance and suggests future research directions to fully exploit Dectin-1's therapeutic potential in managing IBD. By elucidating the complex interplay between Dectin-1 and the gut microbiota, this chapter provides insights into novel therapeutic approaches aimed at mitigating IBD symptoms and improving patient outcomes.
