Tumours are populated with not only malignant cells but also many other resident cells such as macrophages. Normally, macrophages act as the first defense line of the immune system and are specialised to kill and remove disease cells or foreign substances that may be harmful to human body. However, the macrophages in the tumour is a “double edged sword” and can either inhibit or promote tumour growth depending on their polarisation to different phenotypes including pro-inflammatory macrophages (M1; suppress tumour growth) or anti-inflammatory macrophages (M2; promote tumour development). It has been demonstrated that cancer therapy can affect the population of tumour macrophages. A high M1/M2 ratio is linked with extended survival of cancer patients. Therefore, the population of macrophages and the M1/M2 ratio is very important in assessing therapeutic outcome and status of tumour. Our goal is to develop a non-invasive fluorescence nanoprobe (materials science and chemical engineering) to specifically target M1/M2 tumour macrophages (cancer biology). Through this, the population of tumour macrophages and the M1/M2 ratio can be determined via optical imaging (physical science). The information will be used to assess the outcome of anticancer therapy and the status of tumour to guide doctors in treatment.
