Understanding the impact of hyposplenism on the immune system

Open to students

The spleen is an important organ of the immune system and it is often removed for the treatment of different medical conditions, to perform surgery on nearby organs and removed as a consequence of physical trauma (asplenia). However, some people are born without a spleen (congenital asplenia) or their spleen does not function due to haematological blood disorders, cancer and autoimmune diseases (hyposplenism).

Living without a functioning spleen increases a person’s risk of infection with encapsulated bacteria that can cause pneumonia, sepsis and meningitis. People living without a spleen need to monitor for signs of infection and are often required to take lifelong preventative antibiotics.

For people with hyposplenism it is less clear what their immunodeficieny status is and how their conditions impact the effectiveness of their immune responses to different pathogens.

Immunological techniques and high dimensional data analysis

The aim of this project is to identify immune impairments in different cohorts of people who live with hyposplenism. The student/s will characterise immunodeficiencies including changes in the proportion and function of immune cells e.g. T cells and B cells and the effect of immune impairments on the production of immune mediators and inflammation.

Students will learn an array of immunological techniques including cellular and serological using flow cytometric based assays (both conventional and spectral flow cytometry), ELISA and neutralising antibody assays.

Students will learn high dimensional data analysis approaches and work within a multidisciplinary team of virologists, immunologists, clinicians, and nurses across Monash Health and Alfred Health.

There will be opportunities to gain experience in coordinating clinical studies, performing clinical research and collaborating with consumer health organisations like Spleen Australia.
