Mechanism of action

GM-CSF (granulocyte-macrophage colony-stimulating factor) is a cytokine that promotes the differentiation, proliferation, and activation of myeloid cells including neutrophils, macrophages, and dendritic cells. Priming with GM-CSF before other immunotherapies or treatments aims to enhance the immunogenicity of the tumor microenvironment and improve the efficacy of subsequent immune-mediated anti-tumor responses.
