About

Dr. Paul Giacomin is currently a Senior Research Fellow in the Australian Institute of Tropical Health and Medicine at JCU Cairns. Since completing his PhD studies at the University of Adelaide in 2008, his research interests have focussed on understanding the molecular and cellular mechanisms by which immune responses to parasitic helminths (worms) are initiated and regulated. Dr. Giacomin underwent his postdoctoral training at the University of Pennsylvania between 2008 and 2012 in the laboratory of Dr. David Artis, where he was awarded fellowships from the American-Australian Association, as well as the NHMRC, to conduct his research. Dr. Giacomin continued his fellowship at JCU Cairns in 2012, where he continues to investigate the key immune cells and cytokines involved in immunity to intestinal worms, as well as exploring the potential beneficial effects that worm infection may have in alleviating inflammation associated with autoimmune diseases.

Current Funding

Current and recent Research Funding to JCU is shown by funding source and project.

CRC for Developing Northern Australia - Grant

Novel therapeutics for diabetes sourced from Northern Australian biota.

Indicative Funding: $619,633 over 2 years (administered by Macrobiome Therapeutics)
Summary: he aim of this project is to develop lead diabetes drug candidates from hookworm saliva and build a package for multinational commercial investment. The project aims to deliver the following outcomes: 1. Screen a synthetic hookworm library (consisting of hundreds of hookworm proteins) for anti-inflammatory activity and express lead candidates using pharmaceutical industry standard techniques. 2. Assess efficacy of leads in mouse models of diet-induced T2D. 3. Understand the mechanism of lead drug action and prioritize candidates for progression into clinical development. 4. Set the scene for a burgeoning biotech industry in Northern Australia that is differentiated from those in the south, and indeed globally, by capitalizing on the unique biodiversity of the region and the therapeutic opportunities it presents.

Coeliac Australia - Exploratory Grant

Exploring new therapeutic approaches for coeliac disease based on biological effects of hookworm treatment.

Indicative Funding: $45,455 over 2 years
Summary: We hypothesise that hookworm infection creates an anti-inflammatory environment in the small intestine that favours improved gluten intolerance in coeliac disease, and undersstanding the biological mechanisms that lead to improved gluten intolerance will advance the development of novel theraplies that will not require being infected with live worms. The overall aim of this project is to comprehensively profile the biological responses in the gut and faeces using innovative, complementary techniques (RNA-sequencing, transcriptomic imaging and microbiome analyses) and correlate these changes with improved coeliac disease outcomes.

Bill & Melinda Gates Foundation - Grant

Laser based diagnostics for STH infections

Indicative Funding: $43,000 over 2 years (administered by University of Queensland)
Summary: Developing novel laser based methods for rapid diagnosis and quantification of parasitic worm infection in various animal and human biological tissue samples, with the end goal of a point-of-care, rapid and sensitive diagnostic,

National Health & Medical Research Council - Development Grant

Hookworm peptide therapeutic for oral treatment of IBD

Indicative Funding: $732,700 over 2 years
Summary: We intend to develop an orally delivered peptide that can modulate the immune system and be developed as a therapeutic for inflammatory bowel disease. We have identified a peptide, derived from a hookworm protein, that alleviates the clinical symptoms of experimental colitis when orally administered to mice. The peptide has bioactivity with human cells ex vivo and displays desirable drug-like properties. The aim of this project is to acquire further data on the mechanism of action and formulation conditions to facilitate formal product development prior to licensing and clinical trials.

National Health & Medical Research Council - Project Grant

Hookworm therapy for Coeliac Disease: A randomised, double blink, placebo-controlled clinical trial

Indicative Funding: $865,000 over 5 years
Summary: Parasitic worms have an amazing ability to manipulate the immune system, and our research group recently discovered how they may hold the key for treating inflammatory diseases such as Coeliac Disease. The aim of this research is to further develop this novel therapy in a clinical trial and study the mechanism of how worms control the immune response, including identifying the molecules that the worm produces that could be produced as a pill-based medication for treating coeliac disease.

QLD Department of Environment and Science - Advance Queensland Research Fellowship

New therapies for Coeliac Disease: Helminths and their secreted products.

Indicative Funding: $300,000 over 3 years
Summary: Coeliac Disease (CeD) is a common and debilitating autoimmune disorder (affecting 1% of the Queensland population) where gluten ingestion triggers an inflammatory reaction and severe intestinal symptoms. A gluten-free diet is effective for some, but is expensive, inconvenient and inadvertant gluten exposure is common. Hence there is a need for new new treatements for CeD. In a recent clinical trial, our research group demonstrated the efficacy of an unlikely agent to imporive gluten tolerance; parasitic helominths (worms). The overall aim of my research is to translate this movel thereapy into a larger, placebo-controlled clinical trail and study the mechanisms by which worms control the immune response. Identification of the molecules that the worms prodcue to suppress gluten-induced pathology will allow the development of "pill-based" medcations for CeD, and potentially other autoimmune or inflammatory conditions.
