Application of Animal Models of Irritable Bowel Syndrome (IBS)
Currently, no single animal model fully recapitulates the multifaceted nature of human IBS, which involves complex interactions among the gut‑brain axis, psychosocial stress, microbiota dysbiosis, immune activation, and genetic susceptibility. In preclinical research, animal models of IBS are applied across several critical domains. They enable mechanistic studies of visceral nociception, gut barrier dysfunction, low‑grade inflammation, and altered motility patterns.
