creating

every 133 Americans suffer from an autoimmune disorder called Celiac
-
a new
+
Disease
-
way to treat Celiac. Our project has been split into two tasks. The
+
(14, 11). Celiac Disease is a condition in which the small intestines of
-
first is to
+
an
-
produce an inducible secretion system; the second is to construct a
+
affected individual cannot properly digest gliadin, a protein present
-
biological

in gluten.
-
pH sensor to compartmentalize this secretion system in the stomach.
+
When
-
Moreover, this
+
consumed, gliadin induces immune system responses, the
-
pH system will act as a kill switch if this system were to ever leave
+
side-effects of which are,
 +
but not limited to: abdominal pain, chronic diarrhea, and vomiting (14).
 +
Currently, the only accepted treatment for this disorder is adhering to
 +
a
 +
gluten-free diet (14, 12). This can be very difficult as great
 +
varieties of
 +
food contain gluten. This inspired us to imagine an alternative
 +
treatment based on a probiotic organism
 +
that can
 +
survive and take residence in the stomach, where it would secrete an
 +
enzyme that
 +
degrades gliadin.</big></span><big style="font-weight: bold;"><span
 +
style="font-family: &quot;Times New Roman&quot;,&quot;serif&quot;;"><br>
 +
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; Then the design
 +
elements of this organism should satisfy at least two main
 +
criteria.
 +
First, it
 +
should be able to survive only in the stomach; second, it should secrete an
 +
enzyme
 +
that degrades gliadin<i>.</i> We envision that these parts would
 +
not
 +
only be useful for our project, but also to other future projects.</span><span

              It is estimated that about one in every 133 Americans suffer from an autoimmune disorder called Celiac Disease (14, 11). Celiac Disease is a condition in which the small intestines of an affected individual cannot properly digest gliadin, a protein present in gluten. When consumed, gliadin induces immune system responses, the side-effects of which are, but not limited to: abdominal pain, chronic diarrhea, and vomiting (14). Currently, the only accepted treatment for this disorder is adhering to a gluten-free diet (14, 12). This can be very difficult as great varieties of food contain gluten. This inspired us to imagine an alternative treatment based on a probiotic organism that can survive and take residence in the stomach, where it would secrete an enzyme that degrades gliadin.
           Then the design elements of this organism should satisfy at least two main criteria. First, it should be able to survive only in the stomach; second, it should secrete an enzyme that degrades gliadin. We envision that these parts would not only be useful for our project, but also to other future projects.

           We decided to focus our summer project on building the first of the two key elements required for our system:
                1. Produce an inducible secretion system
                2. Construct a biological pH sensor limiting this secretion system to the stomach
