Summary Explore a novel antibiotics-independent treatment for severe bacterial infection by raising innate phagocytosis ability with peptide drugs.
Septic shock contributes to around 8000 deaths annually in Australia. Innate immunity is the first line of host (patient) defence against invading microorganisms. The most dangerous microorganisms are those resistant to antibiotics and in such situations, phagocytosis of these microorganisms by immune cells (such as neutrophils and monocytes) becomes the only line of defence.
Previously, we have found that copper binding proteins (e.g. ceruloplasmin) in serum are potent inhibitors of innate phagocytosis of non-opsonized bacteria. Our preliminary results show that chelation of copper with 1-5 mM tetraethylenepentamine (TEPA, a drug that binds to copper) can neutralize the inhibitory effect of serum thereby restoring innate resistance against bacteria. On the other hand, we have found certain peptides could significantly increase the innate phagocytosis ability. This project aims to study the in vitro effect of copper chelation and peptide drugs either alone or in combination, as well as in vivo therapeutic effect of boost innate immunity in a rabbit or sheep model of sepsis.
Techniques involved are animal (rabbit and sheep) handling, flow cytometry and protein separation.
