The ultimate goal of The ORIGINS Project is to reduce the rising epidemic of non-communicable diseases through 'a healthy start to life'.
As well as ORIGINS long-term core research, there are a number of clinical trials, early interventions and shorter-term research studies that sit within ORIGINS. Known as sub-projects, these studies look at multiple aspects of child and family health and development.
The ORIGINS Project provides researchers, students, clinicians and universities with a unique opportunity to play a crucial role in changing the health of future generations.
Comparing how mast cells are “programmed” in allergic and non-allergic children at one year of age.
The Mast Cell Study aims to compare how mast cells, found within blood samples taken from the ORIGINS cohort at one-year of age, are “programmed” in allergic and non-allergic children.
Allergic diseases affect one in every five Australian children. Already from the first months of life, infants can show signs of allergy such as eczema or skin rashes. Allergies develop because the immune system confuses harmless substances, such as food or pollen with dangerous substances such as parasites or toxins.
As defence, the immune system produces a special type of antibody called IgE. These recognise the substance (allergen) and are in turn recognised by a type of immune cell called mast cells.
When mast cells with allergen-IgE recognises an allergen, they release histamines which leads to the generation of most of the symptoms associated with allergies, such as runny nose, itchiness and swelling.
Recently, research collaborators discovered that mast cells travel to all parts of the body when children are very young and then stay in those body parts throughout life.
As mast cells have such a central role in allergic diseases, they are a very suitable target for new allergy drugs, however we must first better understand how they function and how their function translates into allergic disease.
In this project, we will compare how mast cells are “programmed” in allergic and non-allergic children at one year of age. This is only possible through the development of new and sensitive methods that can detect these very rare cells as they migrate throughout the body.
Aiming to analyse around 60 blood samples, taken at the one-year skin prick allergy tests which occur as part of The ORIGINS Project protocol, there is no recruitment required for this study.
This study is a collaborative project between the ORIGINS cohort, allergy and immune researchers at Telethon Kids Institute in WA and Bioinformatic mast cell researchers in Singapore.
By collaborating on this study, researchers are able to investigate new aspects of how these important cells contribute to allergic disease in children which has not previously been possible.
The Mast Cell Study is a sub-project of The ORIGINS Project and is supported by funding from the Telethon Kids Institute, through a BlueSky grant thanks to BHP.
