The IgGFc-binding protein FCGBP is secreted with all GDPH sequences cleaved but maintained by interfragment disulfide bonds

2021

Mucus forms an important protective barrier that minimizes bacterial contact with the colonic epithelium. Intestinal mucus is organized in a complex network with several specific proteins, including the mucin-2 (MUC2) and the abundant IgGFc-binding protein, FCGBP. FCGBP is expressed in all intestinal goblet cells and is secreted into the mucus. It is comprised of repeated von Willebrand D (vWD) domain assemblies, most of which have a GDPH amino acid sequence that can be autocatalytically cleaved, as previously observed in the mucins MUC2 and mucin-5AC. However, the functions of FCGBP in the mucus are not understood. We show that all vWD domains of FCGBP with a GDPH sequence are cleaved and …

Modulation Of Beta2 and Beta3 Integrins in experimental colitis induced by iodoacetamide and enteropathogenic E.Coli

2013

Integrins can modulate the infiltration of inflammatory cells and the secretion of various inflammatory mediators, essential players in the pathogenesis of colitis. This study explores the role of beta2 and beta3 integrin signaling and their possible role in experimental colitis. A total of 160 adult male Sprague-Dawly rats were divided into 4 equal groups: methylcellulose, bacteria, iodoacetamide and iodoacetamide plus bacteria. Clinical symptoms and signs of colitis were checked daily and colonic tissues were biopsied on days 3, 14, 28, and 56 post induction. Histological studies along with histochemical analysis and polymerase chain reaction of beta2, beta3 and alphavbeta3 were performed…

Modulation of mucin 2 and mucin 3 in colitis induced by iodoacetamide and enteropathogenic bacteria in rats

2016

The iinate and acquired immune systems are both implicarted in the etiology of Inflammatory Bowel Disease (IBD) in addition to the genetic predisposition, the environmental factors and the intestinal flora covering the mucosa. A defect in the mucous covering will lead to an invasion of pathogens and stimulation of the immuune response with aberrations of mucin 2, the major mucin of the mucous layer. Aim: this study aims to assess the modulation of colonic MUC 2 and MUC 3 in a arat model of IBD induced by a combination of iodoacetamide and enteropatogenic E. Coli. Methods: 78 sprague-Dawley female rats were divided into 4 groups. Each group was subjeceted, on a basis, to a rectal injection o…
