Therapeutic Mechanism of CD47 Blockade in Suppressing Melanoma Metastasis
PROJECT SUMMARY The overall goal of this project is to identify molecular regulators enabling immune suppressive properties of metastatic melanoma and define cell lineages that mediate therapeutic function of CD47 blocking antibodies. Our central hypothesis is that metastasizing melanoma cells avoid immune recognition by hyperactivating CD47 promoter through NRF1 transcription factor. Overexpression of CD47 then modulates tumor immune microenvironment in a way that inhibits melanoma destruction and antigen presentation by professional phagocytes while at the same time stimulating myeloid derived suppressive cells (MDSCs) that negatively affect T-Cell responses. When the proposed research…
