Research interest
Resistance to antimicrobial agents and the limited development of novel agents is threaten-ing to worsen the burden of infections that are already a leading cause of morbidity and mortality. This has increased interest in the development of novel strategies for design of antimicrobial drugs and compounds for selective modulation of our natural immune defences. In my laboratory we focus on development of both these classes of anti-infective drugs. The drug candidates we are working with are peptides or peptidomimetics, isolated from bacterial sources (bacteriosins) or designed from naturally occurring host defence peptides through a series of optimization strategies. Parallel to wet-lab strategies like substitution analysis and large screening libraries of peptides we employ state of the art computational in silico modelling techniques developed in collaboration with world class computer scientists, to tailor peptides/peptidomimetics with high activity and specificity. The mi-crobial target we focus on is predominantly multi-drug resistant bacterial strains and different clini-cally relevant virus. The pathogens are either targeted directly (classical antimicrobial peptide drugs) or through host cell immune stimulation (classical innate defence regulators). Both branches requires an in depth mechanistic understanding of how the peptides/peptidomimetics facilitate their activity, involving a wide panel of sophisticated in vitro experiments. Pending the pathogen of interest in vivo models are designed and carried out in collaborations with expert scientists around the world. To complement the peptide design and biological evaluation effort, we are also investi-gating several different delivery systems, e.g.; liposome, micro-spheres, hydro-gels, nano-capillar tubes and tethering strategies.
