Summary
B lymphocytes are a specialised type of blood cells that produce antibodies in response to a pathogen or a vaccine. We have recently discovered that all mature B cells depend for their survival on a previously unknown protein called SPPL2A. This application will investigate the molecular mechanism through which SPPL2A contributes to the survival of B cells. We will also investigate if humans with currently unexplained B cell deficiency have mutations in SPPL2A.
The Relationship Between Maternal And Infant Dietary Intake Of Fermentable Fibre, Gut Microbiota, Short Chain Fatty Acids And Allergic Disease And Asthma: A Population-derived Birth Cohort Study

Summary
The proposed study will involve the Barwon Infant Study (BIS) cohort of 1074 infants to provide the first systematic investigation of the hypotheses that the epidemic of allergic disease and asthma in many parts of the world relates to the paucity of fermentable fibre in the modern diet, and that the protective effect of fermentable fibre is mediated by changes in the organisms that colonise the gut and the metabolites that they produce.
Methylation-sensitive T Cell Genes And Childhood Food Allergy.

Summary
Australia has the highest reported prevalence food allergy in the world. Despite this, little is known about how allergy develops. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of food challenge proven food allergy with assessment of immune functioning & cutting edge genomics, to extensively characterise the pathways leading to food allergy in children.
Understanding The Role Of The Putative Phospholipid Translocase ATP11c In B Cell Development

Summary
The immune system protects humans against recurrent infections with a wide range of pathogens. Formation of antibodies is a crucial element of the immune response. Defects in the production of antibodies can lead to recurrent and often life-threatening infections. This project seeks to understand a genetic defect in mice resulting in an almost complete absence of antibody producing cells, thereby causing a disease that is similar to some forms of human immunodeficiency.
Epigenetic Programming Of Immune Development In Utero: Role Of The Maternal Environment In The Allergy Epidemic

Funding Amount
$764,463.00
Summary
This study will provide new insights into the development of allergic disease. Specifically, we will explore the hypothesis that allergic disease and other disorders or immune dysregulation occur as a result of gene-environmental interactions in early life, and that these events begin in pregnancy when the developing fetus is still developing and most susceptible to these effects.
