Griet Debyser attended the 7th European CF Young Investigator Meeting that took place in Paris on February 27th,28th and 1st March, 2013. She won the 7th EYIM award for presenting her results entitled "A shotgun metaproteomics approach reveals a reduction of butyrate producers in the intestinal microbiome of cystic fibrosis patients" in the form of an oral presentation and a poster.
Novel webtool aids in metaproteomic research.
LProbe researchers Griet Debyser and Bart Devreese shared ideas with researchers of
the Ghent University Lab of Microbiology and the Biocomputing group of Bart Mesuere
and Peter Dawyndt to set up a bioinformatics tools called Unipept (unipept.ugent.be).
Unipept displays a biodiversity analysis based on unique peptides derived from peptide
centered metaproteomic analysis. The webtool is described in a paper to appear in the
Journal of Proteome Research.

The Laboratory for Protein Biochemistry and Biomolecular Engineering (L-ProBE) is an integral part of Ghent University’s flourishing Biosciences community and participates in the Department of Biochemistry and Microbiology in the Faculty of Sciences. It brings together a diverse group of scientists that are distributed among three closely interacting research units
The Unit for Mass Spectrometry and Proteomics (including research activities in Microbial Physiology)
(Head: Prof. Dr. Bart Devreese)
The Unit for Structural Biology and Biophysics
(Head: Prof. dr. Savvas Savvides)
The Unit for Molecular Glycobiology
(Head: Prof. Dr. Nico Callewaert)
Thematically, L-ProBE is situated at the crossroads of Biochemistry, Biotechnology, Microbiology and Biophysics. The group has grown steadily over the years and has been a pioneer in Belgium in the study of structure-function relationships of proteins. Recent research initiatives aim towards the study and engineering of soluble and membrane-asscociated (glyco)proteins of biomedical and biotechnological importance, and proteomic analyses of microbial physiological processes. All projects are collaborative and are supported by extramural funding. L-ProBE frequently publishes research results in prominent, peer-reviewed journals and has offered over the years a rich training ground for scores of undergraduate and doctoral students, post-doctoral fellows, and visiting professors.

L-ProBE researchers provide new insights on the resistance of bacteria against common antibiotics using proteomics technology.
The work was done using the bacterium Stenotrophomonas maltophilia, known as a pathogen involved in hospital acquired
infections. It shows that the bacteria not only produce the enzymes that degrade the antibiotic, but displays a pleiotropic
response involving proteins used for cell wall remodeling.
UGent-wetenschappers ontdekken hoe immuunsysteem inactief gemaakt wordt
Wetenschappers van de Universiteit Gent hebben ontdekt hoe het virus dat onder andere klierkoorts
veroorzaakt, ons immuniteitssysteem uitschakelt.
Klierkoorts is een ziekte waar je weken zelfs maanden
last van kan hebben. Maar onderzoekers weten nu hoe het virus te werk gaat, en dus kunnen ze ook een medicijn ontwikkelen.
Belangrijke ontwikkeling in de behandeling van bloedkanker
Onderzoekers van de UGent ontrafelden de ruimtelijke structuur van de humane Flt3 receptor uit beenmergcellen.
Als deze receptor geactiveerd wordt door een specifieke sleutelstof (cytokine ligand), gaan beenmergcellen zich
verder vermenigvuldigen en ontwikkelen tot celtypes die belangrijk zijn voor de opbouw van immuniteit. De Flt3
receptor werd ruim 20 jaar geleden ontdekt maar de structuur ervan en zijn interactie met zijn cytokine ligand
waren nog niet bekend. De ontdekking is van groot belang voor de behandeling van bloedkanker en werd vandaag
gepubliceerd in het toonaangevende wetenschappelijke tijdschrift “Blood”.

In a collaborative effort with Prof. Dolashka from the Bulgarian Academy of Science,
we obtained the full sequence of the three structural subunits of hemocyanin from the garden
snail Helix lucorum. Hemocyanins are amongst the largest proteins found in nature. They function
as oxygen transporters in mollusks and related organisms, similar as hemoglobin in human blood.
Hemocyanins are attracting interest because of their immuno-modulating properties, and they are used as vaccine carriers.
