Dr Sarah Jones is a Lecturer in Pharmacology and a member of the Molecular Pharmacology Research Group. For the past 15 years, Sarah’s research has focussed on Cell Penetrating Peptides as a means to reach and modulate biological events within the cell. The ability of Cell Penetrating Peptides to target numerous and previously elusive intracellular candidate sites for therapeutic interventions could offer unparalleled opportunities for drug development and expand the repertoire of novel “druggable” targets.

 

With over 40 publications to date, numerous speaker invitations at International Symposia and co-editor of the book Bioactive Peptides, Sarah is now an established figure within the field of Cell Penetrating Peptides. Additionally, she has organized 3 International conferences including; a joint FEBS/Biochemical Society 4-day lecture course "Cell Penetrating Peptides" held at the Royal Society 2013, a Zing sponsored conference "Peptide Therapeutics 2012" and a Biochemical Society Focused Meeting "Cell Penetrating Peptides 2007.

The Molecular Pharmacology of Cell Penetrating Peptides

Cell Penetrating Peptide Technologies now provide a means of delivering previously impenetrable cargoes into the cell’s interior. Currently, Sarah’s endeavours encompass the design, synthesis and evaluation of cell penetrating peptides which target intracellular protein-protein interactions. Such investigations include identification of novel cryptic cell penetrating peptides within key signalling proteins and evaluation of their applicability as biological modulators (Bioportides) of apoptosis, tumour angiogenesis and Parkinson’s disease pathophysiology. The latter of which comprised a pilot study funded by the Michael J Fox Foundation, “Evaluation of LRRK2-derived Bioportides as Functional Protein Modulators and Potential Therapeutics”.

 

Very recently, Sarah’s research has extended to the utility of cell penetrating peptides as novel site-specific intracellular delivery vectors into mammalian sperm. With the ability to deliver bioactive cargoes into the sperm’s interior, such a development now provides the research community with valuable tools to investigate and modulate fundamental processes of sperm physiology and pathophysiology. 

 

Thus, 4 main foci of work which are gaining significant impetus include;

 

Bioportides (bioactive cell penetrating peptides) and Reproductive Health

Identification and refinement of bioportides capable of penetrating human sperm cells to modulate the activities of intracellular proteins that control motility and fertilisation capacity

 

Development of an Innovative Human Mast cell-based Therapeutic Platform

The utilisation of inert CPPs to deliver bioactive cargoes into discrete compartments of human mast cells, and so enable their subsequent exocytosis by the physiological activation of regulated secretion

 

Stabilised Bioportides for Therapeutic Development

Evaluating the influence of chemical modifications on the biochemical and pharmacological properties of second-generation (proteolytically stable) bioportides, thus identifying candidates for therapeutic applications (Parkinson’s Disease and tumour angiogenesis).

 

Peptide Antibiotics

The design, synthesis and evaluation of potent antimicrobial mastoparan analogues with limited secretory and cytotoxic bioactivities towards human cells. Initial screening has been carried out in collaboration with Community for Open Antimicrobial Drug Discovery, Institute for Molecular Biosciences, The University of Queensland and Welcome Trust

 

Strong international collaborative ventures lie at the heart of the molecular pharmacology group and have recently led to the development of a novel glioma-homing peptidyl drug delivery system and European Patent. entitled “chimeric constructs between glioma-homing peptide and cell-penetrating peptide”, this joint patent is with CePeP III AB, Stockholm, Sweden and the University of Tartu, Estonia.

 

Since 2006, Sarah has delivered oral presentations at the biennial European Peptide Symposiums and additional speaker invitations include;
