Abstract:
The aim of the current study was to investigate the expression of chemokine CCL20 in ulcerative colitis (UC) patients and in dextran sulfate sodium (DSS)-induced experimental colitis in mice. The expression of the CCL20 protein in colonic mucosa was detected in 65 UC patients and in 30 normal patients. A total of 40 female BALB/c mice were divided into a control and model group; the latter was fed a 5% DSS solution ad libitum for 7 days to induce experimental colitis. The disease activity index (DAI) and histological score were assessed and the expression of CCL20 mRNA and protein was determined. CCL20 was expressed in the UC group. It was either weakly expressed or not expressed in the normal control group. Additionally, the expression of CCL20 in the UC group was significantly higher compared with that in the control groups (P<0.01). The expression levels of CCL20 mRNA and protein were significantly increased in the model group compared with those in the control group (P<0.01) and positively correlated with the severity of colonic inflammation. The results from the present study demonsrtate that CCL20 positively correlates with UC. CCL20 may play a significant role in local damage and pathological changes in UC and may serve as a potential target for therapy.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
