One such a mechanism involves TGF-&beta;1, a pleiotropic cytokine that targets both immune and non-immune cells in the gut. TGF- &beta;1 is highly expressed in inflamed mucosa of IBD patients but paradoxically it is unable to activate Smad-associated intracellular signalling and suppress inflammatory cytokine responses. This is because IBD-related inflammation is marked by elevated levels of Smad7, an inhibitor of TGF-&beta;1 signalling. Consistently, knockdown of Smad7 with a specific antisense oligonucleotide restores TGF-&beta;1 function, inhibits inflammatory cytokine production, and ameliorates colitis in mice. In this article we review the available data supporting the pathogenic role of Smad7 in gut as well as the results of a recent phase 1 trial assessing the safety and tolerability of a Smad7 antisense oligonucleotide in CD patients.

class="fas fa-user"></i> Irene Marafini, Silvia Sedda, Davide Di Fusco, Michele M Figliuzzi, Francesco Pallone and Giovanni Monteleone </p> <p>In Crohn&rsquo;s disease (CD) and ulcerative colitis (UC), the two major forms of inflammatory bowel disease (IBD) in human beings, the pathological process is driven by an excessive immune response that is directed against components of the luminal flora and inappropriately controlled by immunesuppressive mechanisms. One such a mechanism involves TGF-&beta;1, a pleiotropic cytokine that targets both immune and non-immune cells in the gut. TGF- &beta;1 is highly expressed in inflamed mucosa of IBD patients but paradoxically it is unable to activate Smad-associated intracellular signalling and suppress inflammatory cytokine responses. This is because IBD-related inflammation is marked by elevated levels of Smad7, an inhibitor of TGF-&beta;1 signalling. Consistently, knockdown of Smad7 with a specific antisense oligonucleotide restores TGF-&beta;1 function, inhibits inflammatory cytokine production, and ameliorates colitis in mice. In this article we review the available data supporting the pathogenic role of Smad7 in gut as well as the results of a recent phase 1 trial assessing the safety and tolerability of a Smad7 antisense oligonucleotide in CD patients.</p> <div class="alert alert-info text-left"><b>Clause de non-responsabilit茅:</b> Ce r茅sum茅 a 茅t茅 traduit 脿 l'aide d'outils d'intelligence artificielle et n'a pas encore 茅t茅 r茅vis茅 ou v茅rifi茅.</div> <div class="nav social-icons"> <a class="nav-link w-auto">Partagez cet article</a> <a title="Cliquez ici" target="_blank" href="https://www.facebook.com/sharer.php?u=https://french.longdom.org/abstract/smad7-sustains-inflammation-in-the-gut-from-bench-to-bedside-49498.html" rel="noopener"><i class="fab fa-facebook-f"></i></a> <a class="nav-link" title="Cliquez ici" target="_blank" href="https://twitter.com/share?url=https://french.longdom.org/abstract/smad7-sustains-inflammation-in-the-gut-from-bench-to-bedside-49498.html" rel="noopener"><i class="fab fa-twitter"></i></a> <a class="nav-link" title="Cliquez ici" target="_blank" href="https://www.linkedin.com/shareArticle?mini=true&url=https://french.longdom.org/abstract/smad7-sustains-inflammation-in-the-gut-from-bench-to-bedside-49498.html" rel="noopener"><i class="fab fa-linkedin-in"></i></a> <a class="nav-link" title="Cliquez ici" target="_blank" href="https://plus.google.com/share?url=https://french.longdom.org/abstract/smad7-sustains-inflammation-in-the-gut-from-bench-to-bedside-49498.html" rel="noopener"><i class="fab fa-google-plus-g"></i></a> </div> </div> </div> </div> </section> <footer class="bg-blue-grey-900 py-3"> <div class="container"> <div class="row"> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">Liens de contenu</h4> <ul class="list-unstyled footer-links font-size-3"> <li><a class="" href="https://french.longdom.org/privacy-policy.html" title="Cliquez ici">politique de confidentialit茅</a></li> <li><a class="" href="https://french.longdom.org/terms-conditions.html" title="Cliquez ici">termes et conditions</a></li> <li><a class="" href="https://french.longdom.org/authors-reviewers-editors.html" title="Cliquez ici">Auteurs, critiques et 茅diteur</a></li> </ul> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">Contacter Longdom</h4> <p><strong>Groupe Longdom SA</strong><br /> Avenue Roger Vandendriessche,<br /> 18, 1150 Bruxelles, Belgique<br /> T茅l茅phone : +442038085340<br /> <strong>Courriel :</strong> <a class="white" href="mailto:info@longdom.org" title="Cliquez ici">info@longdom.org</a></p> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">Connecter</h4> <nav class="nav nav-pills social-icons-footer flex-column a-pl-0"> <a href="https://www.facebook.com/longdompublisher" title="Cliquez ici" target="_blank" class="nav-link bg-facebook-hover"><i class="fab fa-facebook-f bg-facebook"></i></a> <a href="https://www.linkedin.com/company/longdom-publishing-sl/" title="Cliquez ici" target="_blank" class="nav-link bg-linkedin-hover"><i class="fab fa-linkedin-in bg-linkedin"></i></a> <a href="https://twitter.com/LongdomP" title="Cliquez ici" target="_blank" class="nav-link bg-twitter-hover"><i class="fab fa-twitter bg-twitter"></i></a> <a href="https://www.instagram.com/longdom_publisher/" title="Cliquez ici" target="_blank" class="nav-link bg-instagram-hover"><i class="fab fa-instagram bg-instagram"></i></a> </nav> </div> </div> <div class="row text-center"> <div class="col"> <p>droits d auteur &copy; 2024 <a href="https://french.longdom.org/" title="Cliquez ici" class="white">Longdom 脡ditions SL</a>.</p> </div> </div> </div> </footer> <!--========================== Scroll To Top ============================--> <a href="#0" class="cd-top js-cd-top">Top</a> <!-- Optional JavaScript --> <!-- jQuery first, then Popper.js, then Bootstrap JS --> <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script> <!--Get the app icon js--> <script> jQuery(function($) { $(window).scroll(function fix_element() { $('#target').css( $(window).scrollTop() > 100 ?
