Macrophages within the tumor microenvironment, also called tumor associated macrophages (TAMs) have been shown to play a major role in the growth and spread of many types of cancer. Cancer cells produce cytokines that cause the macrophages to differentiate into an M2 subtype. We have designed a mannosylated liposome (MAN-LIPs) and successfully showed it to accumulate in TAMs in a mouse model of pulmonary adenocarcinoma. These liposomes are loaded with ⁶⁴Cu to allow tracking by PET imaging, and contain a fluorescent dye in the lipid bilayer permitting subsequent fluorescence microscopy. MAN-LIPs are a promising new vehicle for the delivery of imaging agents to lung TAMs. In addition to imaging, they hold the potential for delivery of therapeutic agents to the tumor microenvironment.

The invention is based on the finding that in mammalian lungs c-myc acts as a molecular switch, specifically inducing an expression pattern in vivo, which results in prototypical mammalian adenocarcinoma of the lung and liver metastasis. A set of factors essential for the processes of tumorigenesis and tumor progression, i.e. cell cycle and apoptosis, cell growth, extracellular signaling, angiogenesis and invasion, is identified, whose expression is significantly changed. In particular, the expression pattern found uncovers the network of molecules leading to mammalian papillary adenocarcinomas of the lung.
