Tumours are known to evade the immune system by a variety of mechanisms, one of which is the recruitment of ‘myeloid-derived suppressor cells’ (MDSC). MDSCs suppress the ability of the immune system’s killer T-cells to destroy cancer cells. It is known that the more MDSCs present, the worse the prognosis or therapy response of the patient. Tumours secrete signal molecules such as interleukin-6 (IL-6) that … Continue reading Researchers uncover more about the elusive pericyte-tumour interaction.
