Dr Marnie Blewitt wants to know how a human being is made: how does a single fertilised egg develop into an adult with millions of cells performing a myriad of different functions.

“How does a cell know which of its 30,000 or so genes should be active and which should be dormant?” says Marnie, a researcher at the Walter and Eliza Hall Institute of Medical Research.

Unravelling the immune system

Erika Cretney is fascinated by the human immune system. “As we find out more about how it works, it seems to grow in complexity,” she says. “I’m not sure that we’ll ever know everything about it.”

Her interest lies in ferreting out the function of genes, proteins and cell types in the immune system, and identifying the roles they play. And with the help of her L’Oréal Australia For Women in Science Fellowship, she is pursuing a new target: a small group of T cells that play a role in controlling inflammation and auto-immune diseases.

The Fellowship will give her the freedom to promote her new field of study at international conferences and it will help with childcare costs as she balances a full-time research career with the needs of her young son. Continue reading Unravelling the immune system
