Hi, everyone. My name
is Leo Ferreira.
I'm an Assistant Professor of
Pharmacology and Immunology at
the Medical University
of South Carolina and
the Hollings Cancer Center in
Charleston, South Carolina.
It's really a pleasure
to tell you today about
gene manipulation applications
in autoimmune disease.

We tend to think of
the immune system
as an army that protects us
from pathogens such as
viruses, bacteria, and cancer.
However, sometimes
the immune system
goes rogue and starts
attacking our own body.
It's like the body is
at war with itself.
This is manifested in
a group of diseases
called autoimmune diseases,
where the immune system
attacks our own tissues.
There are almost 100 different
autoimmune diseases.
You have psoriasis, rheumatoid
arthritis, vitiligo,
thyroiditis, multiple sclerosis,
Type 1 diabetes, and so on.
They are all characterized by
immune attack of
specific tissues.
Something about these
diseases is caused by
the immune system somehow losing
control and attacking itself.

While these autoimmune disorders
are relatively
rare in isolation,
if you combine almost
100 of them together,
they actually affect almost
one in 10 Americans,
which is a very large number
if you think about it.
People have studied the
etiology of these diseases,
how they're caused,
how long they go for,
how to make them better.
It's been extremely challenging
for most autoimmune disorders,
we do not know what causes them.
There are some theories.
It could be a viral
infection, could elicit them,
could be just some damage,
could be just pure bad luck.
There's, of course,
a genetic component,
but it's not perfect.
If you do twin
studies, for example,
and if one twin has
Type 1 diabetes,
only a third of the cases does
the other twin also
have Type 1 diabetes.
These are studies
where same genes,
same upbringing, same
environmental factors.
There's a lot of mystery
as to what causes
autoimmune disease and
what keeps it going.
But even then, what
I will argue during
this lecture is that we can
still treat and even cure
autoimmune disorders,
even if we don't always
know what caused them.
Type 1 diabetes is
