The book starts with an introduction to and history of myeloid-derived
suppressor cells (MDSCs), followed by a description of their
differentiation, their role in the tumour microenvironment and their
therapeutic targeting. It closes with an outlook on future developments.
In cancer patients, myelopoiesis is perturbed and instead of generating
immunogenic myeloid cells (such as dendritic cells, inflammatory
macrophages and granulocytes), there is an increase in highly immature
MDSCs. These cells are distributed systemically, resulting in general
immunosuppression. They also infiltrate tumours, promoting their
progression and metastasis by inhibiting the natural anti-tumour immune
response. As these cells also interact with classical anti-neoplastic
treatments, they have become major therapeutic targets in the
pharmaceutical industry and in oncology research.
