The Institut Bordet Clinical Cellular Therapy Research Laboratory (LTCC) is dedicated to fundamental and translational research in the fields of haematology and immunology cellular therapy.
The LTCC’s main objectives concern:
- study of the interaction between leukaemic cells and their microenvironment;
- establishment of new prognostic factors;
- development of new therapeutic strategies.
Within the field of cellular therapy, the LTCC is studying the functional characterisation of mesenchymal stromal cells obtained from different tissues and their manipulation with a view to increasing their therapeutic potential.
The LTCC is seeking to improve understanding of the physiopathology of chronic lymphoid leukaemia. We have identified new cellular, molecular and epigenetic biomarkers that help to refine patient prognosis and to guide the direction of treatment. An important part of our research focuses on the interaction between leukaemic cells and their microenvironment (via direct contact or via extracellular vesicles), involved in the progression of the disease and on means of interrupting this dialogue.
In the context of cellular therapy, the LTCC has characterised mesenchymal stromal cells (MSCs) from different tissue sources such as bone marrow, adipose tissue, umbilical cord, skin and muscle. The Laboratory’s key interest is the mechanisms involved in the regulation of the different actors of immune response by MSCs and is developing methods to improve the therapeutic effects of MSCs. Research is also aimed at developing acellular systems based on the capacity of MSCs to release extracellular vesicles capable of mimicking their effects. These extracellular vesicles will be characterised in terms of transcriptome, miRNome and proteome.
Cellular therapy pilot studies are also initiated in collaboration with clinical teams after agreement by the Institut Bordet ethics committee.
The LTCC is involved in training students from the Faculty of Medicine, of Biomedical and Pharmaceutical Sciences and from the Hautes Écoles. Students are supervised as part of immersion courses, for their final dissertation and when completing a 4-year doctoral thesis. We are also involved in supervising theses by students from other universities.
