Can Clostridia help
us defeat food allergies?
The problem
of food allergies has risen in different countries. One of those is the UK. Since 1990, the number of annual hospital admissions because of food
allergy reactions has increased by 500%.
There is no
cure to these diseases until now, when a team of scientist from the University
of Chicago lead by Prof Nagler is working on a way to cure these allergic
reactions and give the chance to eat the foods they never could.
The
experiment was about using a kind of gut bacteria (Clostridia) in an experiment
with two groups of mice. It was suspected that because of the lack of this
particular bacteria caused by overusing antibiotics, a high fat diet, excessive
hygiene and infant formula feeding.
One group of
them were treated with antibiotics which caused them to destroy Clostridia and the other wasn’t.
However, both of the groups were in sterile lab conditions from their birth.
These groups were exposed to peanut allergens and both of them produced
antibodies. The ones without antibodies produced more of the antibodies, thus
the ones with less antibodies produced more which leads us to the conclusion
that gut bacteria made the allergic reaction not too strong. Also when Clostridia
was present they produced a high number of signaling molecule, interleukin
(IL-22). When this molecule was neutralized the level of allergen in the
animals’ bloodstreams have increased.
According to
the scientists the first thing you have to do is be sensitized to an allergic
reaction and then input the Clostridia and let it work its magic.
Although
this seams like an ideal solution to the problem Prof Kathryn Nagler says: ‘There
are of course no guarantees, but this is absolutely testable as a therapeutic
against a disease for which there's nothing.’

The blog that you have written has everything that a article has to inform the reader about. Good Job!
ReplyDeleteThis is a fascinating and challenging story to write about, so well done for choosing it. I don't think you have successfully managed to explain to non-specialists how Clostridium has helped the mice deal with allergens. Also, you have not explained your pictures.
