Myeloid cells in regulation of chronic inflammation, autoimmunity and tumor microenvironment

Organization:

University of Turku, Department of Cell Biology and Anatomy, Kiinamyllynkatu 10, FI-20520 TURKU, Finland

The goal of the project:

In this research project the function of myeloid cells in regulation of immune responses is evaluated. This includes chronic inflammations and autoimmunity as well as the role of tumor associated mac-rophages (TAMs) in maintaining an immunosuppressive status in the tumor microenvironment and promotion of cancer cell migration and invasion. Special emphasis is put on the (exosomal) miRNA communication between different cell populations locally and distally. Further, novel treatment mo-dalities based either on hormone receptor signaling or the pleiotropic effects of bisphosphonate (induced) metabolites are being sought to modulate the function of the myeloid cell population more feasible for the patient.
