ABSTRACT
AIM:
To analyze the expression of CCR5 and correlation with the expression ofβ-arrestin 2 in the intestinal mucosa of the patients with inflammatory bowel disease ( IBD) , so as to study the role of CCR5 andβ-arrestin 2 in the pathogenesis of IBD.METHODS:
Paraffin sections of the colonic mucosa were prepared from 53 patients with active IBD, 26 patients with remissive IBD and 30 healthy people.Immunohistochemical EnVision two-step method was used to test the expression of CCR5 andβ-arrestin 2 in the biopsic intestinal mucosa.RESULTS:
The positive rate, strongly posi-tive rate and immunohistochemical score of CCR5 expression in active IBD were significantly higher than those in normal controls or remissive IBD (P<0.05).No correlation of CCR5 expression with clinical severity, lesion distribution, and endoscopic grade in active IBD was observed.The expression ofβ-arrestin 2 was significantly lower in active IBD than that in the remissive IBD and normal controls, and there was a negative correlation ofβ-arrestin 2 expression with CCR5 expres-sion (P<0.05).CONCLUSION:
The expression of CCR5 is higher, and expression ofβ-arrestin 2 is lower, and there is a negative correlation of expression of CCR5 with expression ofβ-arrestin 2 in intestinal mucosa of the active IBD.
