<script type="text/javascript" src="https://2018.igem.org/Template:NEU_China_A/JS-clearCss?action=raw&ctype=text/javascript"></script>
−
    <p>Due to the popularity of fast food and accelerated urbanization nowadays, the number of patients with inflammatory
+
<style type="text/css">
−
        bowel disease(IBD) is rising in Asia. In addition, patients with IBD have an increased risk of developing colorectal
+
    /* reset */
−
        cancer(CRC). Therefore, NEU China A aim to design a biological system against IBD and potential CRC by using engineered
+
    #content nav * {
−
         probiotics this year. To put out the fire in the gut, E. coli Nissle 1917 is selected as our firemen. We empower

         height: unset;
−
         it with an anti-inflammatory device, which includes a sensor to detect the inflammatory signal, an amplifier to enhance
+
         line-height: unset;
−
        the work ability through positive-feedback loop and an effector to secret anti-inflammatory part. Besides, we should
+
    }
−
        watch out the bad guys such as cancer cells or invasive bacterial. So, we choose Saccharomyces boulardii to be our
+
−
        policemen. It is armed with a constitutively expressed myrosinase to turn the glucosinolates, a natural component
+
−
        of cruciferous vegetables, to sulphoraphane which is an organic molecule with known anticancer activity. We also
+
−
        equip our E. coli with this module since the sulphoraphane can inhibit the oxidative stress. In other hand, to restrict
+
−
        the bacterial invasion, the yeast is made to produce Lypd8, a protein represses the move of bacterial by binding
+
−
        to the flagella. Moreover, we decide to use a cold shock kill switch to avoid the escape of our chassis to the environment
+
−
        and more supporting modules will be added if necessary. We hope these modules will incorporate into a functional
+
−
        system eventually. Integrating probiotic therapy with synthetic biology, we envision that the collaboration between
+
−
        the firemen and the policemen will greatly help us to overcome the tough situation in the patient’s gut.

    <h3>Tips</h3>
+
−
    <p>This wiki will be your team’s first interaction with the rest of the world, so here are a few tips to help you get
+
−
        started: </p>
+
−
    <ul>
+
−
        <li>State your accomplishments! Tell people what you have achieved from the start. </li>
+
−
        <li>Be clear about what you are doing and how you plan to do this.</li>
+
−
        <li>You have a global audience! Consider the different backgrounds that your users come from.</li>
+
−
        <li>Make sure information is easy to find; nothing should be more than 3 clicks away. </li>
+
−
        <li>Avoid using very small fonts and low contrast colors; information should be easy to read. </li>
+
−
        <li>Start documenting your project as early as possible; don’t leave anything to the last minute before the Wiki
+
−
            Freeze. For a complete list of deadlines visit the <a href="https://2018.igem.org/Calendar">iGEM 2018 calendar</a>

         The goal of NEU_China_A this year is to design a biological system aiming to alleviate intestinal inflammatory diseases and prevent potential colorectal cancer. We chose E. coli Nissle 1917 as our chassis, a probiotic that is safe for humans. On the one hand, when it senses an inflammatory signal in the intestine, it releases an anti-inflammatory drug (interleukin-10) to put out the fire in the intestines. On the other hand, it can release myrosinase to convert the glucosinolate contained in cruciferous vegetables into sulforaphane. The sulforaphane can both alleviate inflammation in the intestine and prevent colorectal cancer induced by chronic inflammation.

Intestinal homeostasis

Intestinal homeostasis

There are a lot of microorganisms living in the intestines. The intestinal villi and the underlying tissueshave the largest immune cell population in the human body. Harmonious coexistence between the intestinalflora and the immune cells is critical to human health. Consequently, the intestine has evolved severalmechanisms.

  1. In the crypt, the goblet cells secrete mucus covering the surface of the intestinal villi and Paneth cells secrete antibacterial peptides to inhibit bacterial invasion. In addition, the basal stem cells continue to proliferate and differentiate to renew the intestinal epithelium.
  2. Peyer’s patch contains a large amount of lymphoid tissues, which is the key to regulating the immune system's response to pathogens, and is tolerant to harmless microorganisms and food. Dendritic cells in the Peyer’s patch can extend dendrites among epithelial cells, collecting antigen and decomposing it, by which to activate the tolerability of lymphoid cells.
  3. Regulatory T cells secrete IL-10 in the lamina propria, inhibit the immune cells of the lamina propria and epithelial layers, preventing vigorous immunoreaction along with unnecessary inflammation. Once the imbalance of homeostasis in the immune system occurs, it can cause intestinal disease. When this condition persists without intervention, it can lead to inflammatory bowel disease.
