B-cell lymphoma therapeutic innovations

Research topics & objectives

Identifying, at the single cell level, the mechanisms linked to lymphocyte exhaustion in lymphomas, particularly within innate immunity populations; identifying new therapeutic targets in the lymphoma microenvironment; generating a screening platform on primary tissue samples of patients cultivated in 3D, in order to offer personalised medicine.

Research topics

Characterisation of the resistance mechanisms linked to lymphocyte exhaustion in B-cell lymphomas, particularly via the expression of immune checkpoints, with the aim of improving treatments and progressing towards a personalised medicine.

Key words

Lymphoma, immunotherapies, innate immunity, immune checkpoint and ScRNAseq.
