Immune Evasion - Group van Strijp


Identification of (novel) bacterial proteins and functional characterization of their potential as immune evasion molecule. In the first place these molecules explain why pathogenic bacteria are able to survive and replicate in the human body. Next, they lead researchers directly to key immunological functions. Also they are leads for anti-inflammatory therapy in our Drugs form Bugs program, using structured peptides as mimics. Finally they represent essential virulence factors and therefore prime targets for vaccine strategies and antibody therapy.
