Abstract

Inflammatory Bowel Disease (IBD) is characterized by chronic inflammation in the gastrointestinal tract, and is usually accompanied by dysbiosis in the gut microbiome, a factor that contributes to disease progression. Excessive production of reactive oxygen species (ROS) because of gut microbiome dysbiosis—one of the hallmark features of IBD—promotes chronic inflammation and facilitates the transformation of normal cells into senescent cells. Cellular senescence is associated with the development of various chronic and age-related diseases. We hypothesise that senolytic agents, specifically dasatinib (D) and quercetin (Q), could have a beneficial effect on both the gut microbiome and intestinal cells in IBD. The modulatory effects of a combination of D + Q was assessed in the M-SHIME model with faecal microbiota sourced from Crohn's disease patients. D + Q significantly modulated butyrate and lactate levels in the samples from specific patients. In addition, metabolomic analysis showed that D + Q positively impacted the abundance of anti-inflammatory bacteria while also significantly reducing the several species of pathogenic bacteria. Findings from a Caco-2 cell/THP1 co-culture model of IBD demonstrated that D + Q exerted strong immunomodulatory effects on the gut epithelium, evidenced by reduced NF-kB activity, and lower levels of the pro-inflammatory markers TNF-α, CXCL-10, and MCP-1. Furthermore, D + Q induced the secretion of anti-inflammatory cytokines, including IL-6 and IL-10. However, it should be noted that D + Q also led to the secretion of the pro-inflammatory cytokines IL-8. These findings suggest that D + Q could offer a novel therapeutic approach for advanced IBD management by modulating both the gut microbiome and inflammatory pathways. The results support the potential repurposing of senotherapeutic agents as a strategy for addressing the chronic inflammation central to IBD pathogenesis
