"The functional plasticity of macrophages allows an adaptative response to environmental signals."


The identification of rational approaches based on molecular understanding of Radio-Onco-Immunology should help to better select new combinatorial therapeutic strategies to fight against cancer.


Understanding « tumor-host » interactions is crucial for the development of novel immuno-oncology therapeutic approaches:

  • Tumor-associated macrophages (TAMs) are key components of the cancer microenvironment.

  • The functional plasticity of macrophages allows an adaptive response to environmental signals.

  • TAMs infiltration is associated with treatment resistance and poor clinical outcomes in the majority of cancers.

Therefore reprogramming of TAMs from anti-inflammatory to the pro-inflammatory phenotype is proposed to improve effectiveness of conventional anti-cancer treatments and immunotherapies.

Distinct transcriptional programs can be induced to shape macrophage functional phenotypes.


Findimmune researchers have characterized a novel macrophage immune checkpoint and signalling pathway that dictates pro-inflammatory and anti-inflammatory phenotypes of macrophages.

Findimmune initiated drug screenings to identify modulators of this novel immune checkpoint and select candidates for macrophage reprogramming to favor:

  • A pro-inflammatory phenotype in the context of cancer treatment

  • An anti-inflammatory phenotype for the treatment of immune-related diseases, with one candidate F2001 to fight cytokine storm of acute respiratory distress syndrome.
