This is incredibly fucking important. If our researchers and stroke leadership don't immediately use this to figure out how to reduce the inflammation in our arteries they should be shot. That was my measured opinion, don't follow me.

Our immune system is vital to us and can sometimes overreact causing
chronic illnesses, such as for instance rheumatism and allergy. Now,
researchers from Umeå University and University of Gothenburg have
identified a molecular switch – MYSM1 – that can suppress such an
overreaction and avoid inflammation. The study is published in the
prestigious journal Immunity.
“The discovery of MYSM1 is a major milestone in our understanding of
how our immune system works, and how its response could be controlled in
order to prevent inflammatory diseases such as sepsis,” says Nelson O.
Gekara, research leader at MIMS, Molecular Infection Medicine Sweden at
Umeå University.
Our innate immune system is activated when our body needs to protect
itself against pathogens, for instance bacteria and viruses, as well as
for tissue healing. In some people, the immune system overreacts which
can cause chronic inflammatory diseases and result in tumour
development. The innate immune system is activated by receptors that
recognise certain molecular patterns found on microbes or dead cells.
These receptors are called pattern-recognition receptors (PRRs).
“Most infectious or inflammatory situations are associated with the
simultaneous or sequential activation of multiple PRR pathways.
Therefore, it is essential to avert a disproportionate self-destructive
immune response in a synchronised fashion once activated. How this is
accomplished has been unclear,” says Nelson O. Gekara.
Nelson O. Gekara’s at Umeå University and his doctoral student Swarup
Panda are now closing in on a solution. For years, they have been
searching for possible genes required for the regulation of the immune
system. Together with Professor Jonas A Nilsson at Sahlgrenska Cancer
Center at the University of Gothenburg, the Umeå researchers have now
identified MYSM1 – a molecule in the cell core (nucleus) of resting
cells. For the first time, the researchers are now able to show that
during infection or inflammation MYSM1 accumulates outside of the
nucleus, in the cytoplasm where it disrupts the function of signalling
molecules involved in activation of PRR pathways, thereby terminating
inflammation.
“MYSM1 can be said to act like a molecular switch that can turn off
several inflammatory pathways. Therefore lack of MYSM1 in animal results
in unrestrained activation of the innate immune system, leading to
inflammatory diseases” says Nelson O. Gekara.
His research team is now screening for small molecule compounds that
are able to modulate the MYSM1 molecule activity. The hope is to find
new therapeutics against infections and other inflammatory diseases.
