Role of glial cell line-derived neurotrophic factor in intestinal inflammatory diseases

Glial cell line-derived neurotrophic factor (GDNF), a member of the neurotrophic factor family, promotes the survival, proliferation, migration, differentiation, and axonal growth of intestinal neurons. With studies on the role that enteric glia cells (EGCs) play in intestinal inflammation, GDNF has come into vision as an anti-inflammatory factor in the gut. Recent studies have gradually witnessed that, besides the role in protecting the intestinal epithelial barrier, GDNF plays an important part in a variety of protective mechanisms against intestinal inflammation, and has become the focus of numerous defense mechanisms in intestinal inflammation. GDNF also plays a very important role in the occurrence and development of intestinal inflammatory diseases. This review summarizes the results of recent studies in this field to fully discuss the roles of GDNF in the occurrence and development of intestinal inflammatory diseases.

Role of enteric glial cells in inflammatory bowel disease

The etiology and pathogenesis of inflammatory bowel disease are currently unknown. It is generally believed that persistent intestinal infection, intestinal mucosal barrier defect, intestinal mucosal immune dysregulation and genetic and environmental factors together contribute to the pathogenesis of inflammatory bowel disease. Several studies have demonstrated that enteric glial cells play an important role in maintaining the integrity of intestinal mucosal barrier. Enteric glial cell deficiency in mice leads to the destruction of integrity of intestinal mucosal barrier, increases mucosal permeability, and results in intestinal inflammation, hemorrhage and necrosis. This article discusses the role of enteric glial cells in the occurrence and development of inflammatory bowel disease.

Brain-gut interactions and inflammatory bowel disease: Implications for acupuncture and moxibustion treatment

Inflammatory bowel disease is a chronic recurrent intestinal inflammatory disorder. The role of dysfunction of brain-gut interactions in the pathogenesis of IBD has recently been intensively investigated. Numerous studies have shown that the central nervous system, the hypothalamus - pituitary - adrenal axis (HPA axis), the hypothalamus - the autonomic nervous system axis (HANS axis), and intestinal response functions develop varying degrees of dysfunction in IBD patients and are closely related to disease activity. It has been proven that acupuncture and moxibustion therapy is an effective means for the treatment of IBD, and the holistic regulation of the function of brain-gut interactions may be the key effect mechanism of acupuncture and moxibustion treatment in IBD. In this paper, we aim to explain the mechanism of brain-gut interactions in IBD as well as traditional Chinese medicine theory on brain-gut interactions, and on this basis, we explore the possible mechanism of acupuncture and moxibution treatment.
