PROJECT
More than just nutrition - the synergistic effects of the immune components in human milk
How immune factors in breast milk grow and protect our babies
There are a host of immune components in human milk that protect the infant against infections and diseases as well contributing to the maturation of the infant immune system.
The level of these immune components change in response to changes in the health of the lactating women and her infant. However, the interaction of these immune components in protecting and responding infections and diseases is not well understood. Therefore, this project sets out to investigate which immune components are strongly related to specific infections and diseases, and determine how they interact to provide protection for the infant.
Project goals:
- Determine the level and dose of human milk immune components in relation to infant growth, development and health over 12 months of lactation
- To explore potential changes in the immune components in the milk in response to maternal or infant illness
This PhD student project will involve the application of a variety of different methods to measure the concentration of immune components in the milk such as lactoferrin, lysozyme as well as cytokines.

Research team leader: Professor Donna Geddes
Prof Geddes is a lactation biologist, with a major focus on the mechanisms by which breastfeeding programme early and later life health outcomes. She is located at the School of Molecular Sciences at UWA where she measures milk composition in relation to infant outcomes. She leads a large group that works in the areas of human milk microbiome, metabolomics, biochemistry and physiology.
