CLEC-1

CLEC-1

OSE’s R&D teams have characterized the myeloid checkpoint CLEC-1 (a C-type lectin receptor) as a new therapeutic target in immuno-oncology and identified monoclonal antibody antagonists blocking this novel “Don’t Eat Me” signal. CLEC-1 antagonist monoclonal antibodies have been identified as an innovative immunotherapy that releases the brakes on macrophage phagocytosis and dendritic cells and demonstrates synergistic anti-cancer effects, in particular when paired with chemotherapy.

CLEC-1-500

The identification of CLEC-1 and its antagonists constitute an exciting innovative step in cancer immunotherapy.
