USE OF INHIBITORS OF STRESS GRANULE FORMATION FOR TARGETING THE REGULATION OF IMMUNE RESPONSES

摘要

The mechanisms of tumor escape are numerous, but the immunosuppressive action of coinhibitory molecules has emerged this last decade as the most attractive one for imaging new treatments of cancer. Activation of lymphocytes is indeed regulated by both costimulatory and coinhibitory molecules also called "immune checkpoints". Now the inventors show that T cell activation triggers mRNA and protein expression of stress granule components and more particularly show that immune checkpoint mRNA interact with said stress granules. More importantly, stress granule inhibitors impair expression of immune checkpoint and thus represent an attractive target for targeting the regulation of immune response.
