The Dendritic Cell Biology & Therapeutics Group

Lab head: Professor Derek Hart
Location: ANZAC Research Institute, Concord Hospital

The Dendritic Cell Biology and Therapeutics Group at the ANZAC Research Institute is a newly established research program focused on understanding dendritic cell biology to enable the development of new ways to treat haematological diseases. The group is a translational research group with projects suitable for candidates interested in basic biology or more clinically focused work. The four main areas of focus include:

1.    DC Antigen Discovery and Antibody Engineering


We have identified a number of potential novel biomarkers expressed by dendritic cells. An interested student would design and generate reagents to follow the expression of these biomarkers to discover how they may contribute to dendritic cell function.

Part of our core business is generating antibodies that can be developed for the purpose of using dendritic cells for the diagnosis and treatment of haematological diseases. In this project a student would gain the skills in antibody engineering and phage display. These techniques will be used to develop humanised antibodies and identify novel proteins that bind dendritic cells.

2.    Dendritic Cell Biology – Fundamental and Applied


CD300 is a family of immune-regulatory proteins that can positively and negatively regulate dendritic cell signalling. This project would allow a student to investigate the contribution of CD300 molecules in haematological diseases.

CD302 is a DC specific molecule that plays a role in the migration of dendritic cells. A student would be involved in characterising a gene knockout model of CD302 and the effects on dendritic cells.

AHCYL-1 is another DC molecule that we have found be important in Ca2+ signalling in dendritic cells. Like the CD302 project, a student would be involved in characterising a gene knockout model.

3.     Immunostimulation/Cancer Vaccination


We are developing and optimising strategies the purification and clinical use of dendritic cells to enhance immunotherapy treatment options for patients with multiple myeloma, acute myeloid leukemia and prostate cancer. The strategies being developed have the potential to be generic eventually allowing some overlap with other disease treatments.

Potential students would participate in the development of therapeutic dendritic cell vaccinations strategies and apply these to preclinical animal models of haematological malignancies. Students would gain experience in several molecular techniques including real time PCR, cloning, in vitro-transcription of mRNA tumour antigens. Additionally the student will be exposed to a variety of cellular immunological techniques including cytokine analysis, generation of tumour specific cytotoxic T cells as well as gain experience in cell isolations strategies using flow cytometry.

4.     Immunosuppression/Anti-inflammatory

Our program is ultimately focused on developing novel therapies for haematological disease such as multiple myeloma and acute myeloid leukemia and understanding the balance between graft versus leukemia (GVL) and graft versus host disease (GVH) in Bone Marrow Transplantation. We have a number of projects investigating the role of dendritic cells in these conditions using patient samples. 

In particular, we are developing therapeutic antibodies that can be used to deplete activated dendritic cells causing GVHD whilst retaining the dendritic cells required for GVL. Students would gain experience in flow cytometry, cellular assays and animal models and work closely with clinicians actively involved in treating these conditions. There is an opportunity to work as a student on aspects of our novel anti-CD83 therapeutic project.

Examining the role of the novel C-type lectin receptor DCL-1 (CD302) in innate and adaptive immune responses.

Primary supervisor: Derek Hart

The Dendritic Cell Biology and Therapeutics Group at the ANZAC Research Institute has forged a strong reputation in fundamental human dendritic cell research. Using its extensive clinical links and commercial collaborations, it is developing diagnostic and therapeutic antibodies for novel targets with application in clinical transplantation and the treatment of haematological and other malignancies.

The C-type lectin receptor family of molecules play important roles in the immune system through their ability to recognise conserved structures on foreign pathogens and altered structures on damaged cells1. Our group has identified a new member of this family, named DEC205 associated C-type Lectin-1 (DCL-1) or CD3022,3. The ligand recognised by DCL-1 is yet to be discovered and may or may not be pathogen derived. Nonetheless, our initial studies in humans have shown that DCL-1 is highly expressed on dendritic cells, monocytes, macrophages and granulocytes, pointing to a significant role within the immune system2. In preliminary work, the molecule appears to be multi-functional, with some capacity as an antigen-uptake receptor, but it may also play a role in cell adhesion and migration. Furthermore, DCL-1 is also likely to mediate additional functions due to its unusual capacity to form a fusion protein with the extracellular region of another C-type lectin receptor protein, DEC2053,4. Thus we see DCL-1 as an attractive target for potential therapeutic manipulation of immune responses.

To investigate the biology of DCL-1 in vivo, we have generated DCL-1-deficient (knock-out (KO)) mice. The honours project will involve investigating the role of DCL-1 in haematopoiesis, leukocyte trafficking and innate and adaptive immune responses by performing comparisons of DCL-1 KO and control wild type (WT) mice. The student will learn several laboratory skills including flow cytometry, real-time PCR, cell culture, isolation of lymphoid populations through magnetic- and fluorescence-activated cell sorting and various techniques involved in using mice as a model for studying immune function. As we are a strong translational laboratory, there are also options to collaborate on investigating DCL-1 biology in humans.
