Dr. Roland Ruscher obtained a German Diploma (~MSc) from University of Cologne and the German Aerospace Center (DLR) in Germany, and a PhD in 2014 in the field of immunology from University of Queensland, Translational Research Institute in Australia. He then joined Prof. Kristin Hogquist’s group at the University of Minnesota (UMN) in the USA as a Postdoctoral Fellow, where he studied the development and ontogeny of specific immune cells in the gut, named intraepithelial lymphocytes (IEL). In July 2018 Dr. Ruscher returned to Australia and accepted a position sponsored by the Queensland based biotech company Paragen Bio. In 2020, he became a Research Fellow in Prof. Alex Loukas' group at James Cook University.

Dr. Ruscher's primary interests encompass intestinal and T cell immunology. The immune system and microbial community of the gut have an enormous influence on overall health, yet there are still huge knowledge gaps waiting to be explored. Dr. Ruscher strives to advance our understanding of the gut immune system, and its effects on allergies, and inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.

His major scientific achievements include the discovery of a novel precursor cell to a subset of intestinal IEL (Ruscher et al., Nature Immunology 2017), and characterisation of their establishment in the gut in early life (Ruscher et al., Journal of Experimental Medicine 2020). Dr. Ruscher has also been crucially involved in defining developmental pathways of regulatory T cells (Owen et al., Nature Immunology, 2019).

Dr. Ruscher's current research focus comprises immune responses to parasitic helminths. These worms were shaped by millions of years of co-evolution with their mammalian hosts, and efficiently reduce host inflammatory responses in order to avoid expulsion. Dr. Ruscher studies such anti-inflammatory properties to harness them for the development of therapeutics. He is particularly interested in T cell responses to helminths, and how immunity at mucosal surfaces is modulated by molecules secreted by helminths.

At this early career stage, Dr. Ruscher has won multiple awards and prizes for his research (see ‘Honours’ section), gave a number of invited presentations and seminars, is currently supervising 4 PhD, MSc and Honours students, and is holding Chief Investigator (CI) positions on a NHMRC Ideas Grant and a NHMRC Development Grant, respectively (see 'Current Funding').

Age-associated properties of intraepithelial lymphocytes, and their relation to intestinal diseases

Indicative Funding
$600,740 over 5 years
Inflammatory bowel disease (IBD) and colorectal cancer are a severe burden to those affected. While the peak onset age of IBD lies in early adulthood, colorectal cancer predominantly affects people over 50 years of age. How gut immunity fails in the context of age is poorly understood. This program will establish cornerstones of the intestinal immune system over different stages in life, and thereby help to design better treatment strategies that are adjusted to an individual?s age.

Discovering novel drug lead molecules for inflammatory bowel disease from Australian Aboriginal tropical medicinal plants

Indicative Funding
$1,209,524 over 5 years
Inflammatory Bowel Disease is a debilitating disease, which has no cure. It costs the Australian Health System billions of dollars in hospitalisation, management and lost productivity, thereby precipitating the need for novel drugs. Building on my extensive preliminary data, we aim to discover novel drug leads from Aboriginal medicinal plants, which are currently used for treating inflammatory conditions by the Mbabaram community of the Atherton Tablelands.

Childrens Hospital Foundation - Research Grant

Novel biologics for pediatric inflammatory bowel disease and necrotising enterocolitis, inspired by host-parasite co-evolution.

Indicative Funding
$50,000 over 2 years
Inflammatory bowel diseases (IBD) pose a major health burden with severe symptoms, and IBD onset in childhood is on the rise. Necrotising enterocolitis (NEC) is another inflammatory bowel condition that affects preterm infants, and in which inflamed parts of the gut die. Current treatment methods are insufficient. Intestinal parasites have developed strategies to modulate our immune responses through secreted proteins. We identified seven helminth-secreted proteins that suppress gut inflammation. We now would like to assess which of our preselected proteins are best in the context of early life IBD and NEC.

Hookworm peptide therapeutic for oral treatment of IBD

Indicative Funding
$732,700 over 2 years
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.
