NOVEL MOLECULAR TARGETS IN NASH
Non-alcoholic
steatohepatits (NASH) is inflammation and damage to the liver due to a build-up
of fat. It is part of a group of
conditions referred to as non-alcoholic fatty liver diseases. It is similar to the kind of liver disease
caused by long term, heavy drinking but people with NASH drink little or not at
all.
New treatments
for inflammatory diseases like NASH could be on the way thanks to a significant
discovery made by a group of scientists led by Professor Luke O’Neill. About eight years ago, they came across the
compound MCC950, and began to explore its potential uses. This molecule was
previously developed, then abandoned, by Pfizer two decades ago as a possible
treatment for arthritis.
These researchers
have found that MCC950 directly inhibits NOD-like receptor protein 3 (NLRP3). NLRP3 is a central mechanism
of liver inflammation, injury and fibrosis in various liver diseases including
NASH. The study showed that MCC950 is
effective at inhibiting, or reversing inflammation, injury and fibrosis in two
different models of NASH.
This suggests that MCC950 may be used to treat a myriad
of inflammatory diseases. Furthermore,
the anti-inflammatory effects of MCC950 were not associated with inhibition of
other components of the inflammasome complex that are important for control of
infection.
Professor O’Neill and his team hope to form a company to
further develop and test this compound.
It could be 10-15 years before it could be fully approved for use in
more complex diseases like Multiple Sclerosis or Alzheimer’s.
