The present invention relates to antibodies targeting Tumor Associated Macrophages (TAMs) and uses thereof. The inventors investigated specific marker exposed on the surface of the macrophages associated to tumor in order to detect and target TAMs. They showed that sideroflexin 3, which is absent in normal macrophage, is expressed by tumor associated macrophages. The inventors further demonstrated that using antibody directed to sideroflexin 3, they depleted TAMs in PBMC sample obtained from LCC patient, and strongly reduced leukemic B cells number.
