Unraveling the role of autophagy regulation in Crohn's disease: from genetic mechanisms to potential therapeutics.

Autophagy serves as the primary intracellular degradation mechanism in which damaged organelles and self-cytoplasmic proteins are transported to the lysosome for degradation. Crohn's disease, an idiopathic chronic inflammatory disorder of the gastrointestinal tract, manifests in diverse regions of the digestive system. Recent research suggests that autophagy modulation may be a new avenue for treating Crohn's disease, and several promising small-molecule modulators of autophagy have been reported as therapeutic options. In this review, we discuss in detail how mutations in autophagy-related genes function in Crohn's disease and summarize the modulatory effects on autophagy of small-molecule drugs currently used for Crohn's disease treatment. Furthermore, we delve into the therapeutic potential of small-molecule autophagy inducers on Crohn's disease, emphasizing the prospects for development in this field. We aim to highlight the significance of autophagy modulation in Crohn's disease, with the aspiration of contributing to the development of more efficacious treatments that can alleviate their suffering, and improve their quality of life.
