Laura Mackay is a Laboratory Head at the Peter Doherty Institute for Infection and Immunity at The University of Melbourne and holds an Adjunct appointment at the Singapore Immunology Network at A*STAR in Singapore. She is currently a Howard Hughes Medical Institute (HHMI) and Bill & Melinda Gates International Scholar, a Dame Kate Campbell Fellow, a Sylvia & Charles Viertel Charitable Foundation Senior Medical Research Fellow, and a National Health and Medical Research Council (NHMRC) Leadership Fellow. Laura obtained her PhD from The University of Birmingham, U.K. in 2009, before taking up a post-doctoral position with Professor Francis Carbone at the University of Melbourne. She established an independent group at the Doherty Institute in 2016. Her laboratory studies memory T cell responses, with a focus on the signals that control tissue-resident memory T cell differentiation, with a view to harness these cells to develop new treatments against infection and cancer.

  • Key Achievements
    • For a number of years, Laura has been at the forefront of research into tissue-resident memory T cells and their involvement in viral and tumour immunity, which has resulted in publications in Journals including Science, Nature, Nature Immunology, Nature Medicine, Immunity and PNAS. Her research is supported by the National Health and Medical Research Council (NHMRC), Australian Research Council (ARC), Howard Hughes Medical Institute (HHMI), Bill & Melinda Gates Foundation, Sylvia & Charles Viertel Charitable Foundation, The Michelson Foundation and a Collaboration Agreement with Pfizer. Laura is listed as a Highly Cited ResearcherTM and work has been recognised by Awards including The Gottschalk Medal (2019, Australian Academy of Science), The Prime Minister’s Prize for Frank Fenner Life Scientist of the Year (2019), Eureka Prize for Outstanding Early Career Researcher (2019), The Woodward Medal in Science and Technology (2019) and The Michelson Prize for Human Immunology (2018) and The Victorian Young Tall Poppy Award (2016). She serves on Editorial Boards including Science Immunology and Trends in Immunology, and Strategic Advisory Boards including The Lymphoid Dynamics and HIV Persistence Program in Durban, South Africa, and The Singapore Immunology and Inflammation Cluster. Laura is a permanent co-host on National Triple R Radio science show Einstein-A-Go-Go and is the current serving President of The Federation of Immunological Societies of Asia-Oceania (FIMSA).

    • The role of resident memory T cells in barrier immunity and autoimmune disease

      Infections are commonly acquired through barrier tissues such as the skin, gut and lung, hence establishing memory CD8+ killer T cell populations at these sites is critical for effective immune protection. While most memory T cells circulate in the blood, a distinct lineage, termed tissue-resident memory T cells (Trm), resides and remains in peripheral tissues. Laura’s group’s work has shown that these cells form a defensive barrier providing immediate local control of viral infection. Using methods including flow cytometry, histology and intravital 2-photon microscopy, current work focuses on how Trm cells respond following secondary infection, and they are developing novel strategies to boost Trm cell responses, which aim to facilitate the development of strategies to exploit these cells in vaccination settings. Work in the laboratory also aims to understand the role of Trm cells in autoimmune conditions such as psoriasis, and Laura’s group is investigating new approaches to eliminate pathological cells from peripheral tissues.

    • Understanding the regulation of tissue-resident memory T cell development

      Laura’s group’s work has shown that tissue-resident memory T cells (Trm) are phenotypically and functionally distinct to memory T cells in the circulation. They have found that Trm development is a multistep process that requires the action of several molecules, and that these cells acquire a unique transcriptional profile during their differentiation. Using several different infectious models including Influenza, herpes simplex virus, Listeria and LCMV, Laura’s group is investigating the regulatory cues and mechanisms that govern Trm cell development in different tissues, with a focus on the transcriptional networks that regulate commitment to this immune cell lineage.

    • Identifying the mechanisms of immune cell development in peripheral tissues

      It is now clear that ‘tissue residency’ extends past the T cell lineage, and that various immune cell populations including innate lymphoid cells (ILC) and NKT cells, can persist long-term in peripheral tissues. Laura’s group is interested in the role of the tissue microenvironment in shaping these immune cell populations, and are studying the tissue-tropic factors and signals that govern the environmental adaptation of immune cells to different tissues. Their work also investigates common mechanisms that are required to establish tissue residency such as the shutdown of tissue egress, and they are deciphering novel factors required for these processes. Their goal is to provide a molecular framework for tissue-resident lymphocyte differentiation, which will provide a basis for targeting these cells in future immune cell-based therapies.
