RCSI: Discovery of new corrector drugs that target the genetic mutation which is the underlying cause of cystic fibrosis, rather than the symptoms, is key to developing effective treatments for the condition, an expert in cystic fibrosis drug discovery has said.
CF is caused by mutations that abolish the function of CFTR, a protein
that is needed to transport chloride and bicarbonate across cell
membranes. CF mutations have been grouped in classes according to the
mechanism through which they affect this protein. 10% of all CF patients
with class 3 mutations can benefit from a recently approved drug,
Kalydeco, which has shown to be highly effective. However, the majority
of CF patients (70-90%) have different mutation (F508del) and require a
different type of pharmacological treatment.
In his talk entitled "Pharmacological correction of the cystic fibrosis
basic defect: problems and opportunities", Professor Luis Galietta will
describe how present scientific research efforts are directed towards
the identification of drugs, known as correctors, which can lessen the
effects of F508del mutation. Professor Galietta and his team are among
those who have been researching effective correctors by various
strategies, including screenings on cultured cells of large collections
of chemical compounds looking for molecules that improve the stability
and function of mutant CFTR protein.
Cystic fibrosis (CF), one of the most frequent genetic diseases, is
characterised by a progressive and irreversible damage of lungs,
pancreas, and other organs. Ireland has the highest proportion of CF
people in the world with approximately 1,200 patients suffering from
this inherited chronic disease. (Source: Cystic Fibrosis Ireland)
RCSI's annual Research Day provides scientists with the opportunity to
showcase their most recent research findings. The latest advances in
biomedical sciences, clinical research, population health sciences,
healthcare delivery and health professions education are just some of
the topics featured in studies which will be presented today to more
than 300 researchers who are expected to attend.
Professor Ray Stallings, Director of Research at RCSI said: ‘RCSI is
committed to supporting and nurturing an active research community and
the annual Research Day is a vital platform for highlighting the scope
of research taking place across the different disciplines in the
College. As one of Ireland's premier research institutions, exposure to
world-class research begins at undergraduate level right up to the
highest-calibre research-active academic staff, enabling us to train new
generations of researchers and clinician scientists. We are delighted
to welcome Professor Luis Galietta to share his renowned expertise in
cystic fibrosis drug discovery to present his ground-breaking research
with us.'
The emphasis for RCSI Research Day is on research presentations by
investigators early in their career, post-doctoral fellows,
post-graduate and undergraduate scholars and academic staff. All oral
presentations and poster presentations will be judged and awards will be
presented at a ceremony later this evening.
