CSF-1R Inhibition (CSF-1Ri): CSF-1R is a receptor on myeloid cells. By inhibiting this receptor with drugs like PLX3397, you can reduce the number and/or function of immunosuppressive myeloid cells, including TIMs. In the context of GBM, CSF-1Ri aims to reprogram or inhibit these immunosuppressive cells, thereby improving the efficacy of other immunotherapies, and in our case, specifically to improve the efficacy of DCVax-L.
imo CSF1-R doses the right amount of T cells that enter the tumor.
