High grade serous ovarian cancer ascites exhibit an impaired immune environment – immunosuppressive & protumoral – detrimental to the immune response

AACR IO 2025 High grade serous ovarian cancer ascites exhibit an impaired immune environment – immunosuppressive & protumoral – detrimental to the immune response

Background Malignant ovarian cancer ascites are increasingly recognized as major contributors to tumorigenesis and cancer progression. Ascites create a complex microenvironment where tumor cells interact with soluble mediators, metabolic factors, and immune cells. These interactions can influence tumor behavior, immune response, and treatment sensitivity. Characterizing the immune and metabolic composition of ovarian cancer ascites, together […]

Profiling of immune cell components and soluble factors in ovarian cancer ascites highlights impaired immune environment

AACR 2023 Profiling of immune cell components and soluble factors in ovarian cancer ascites highlights impaired immune environment

Background Ovarian cancer ascites are increasingly recognized as important contributors to ovarian cancer progression. The behavior of tumor cells is strongly influenced by the composition of their surrounding microenvironment. Characterizing the cellular and soluble composition of ascites is therefore essential to better understand how this specific milieu affects tumor progression. In particular, ascites may contribute […]

Ovarian cancer ascites display altered immune environment featured by enhanced soluble factors and suppressive cellular context

Ovarian cancer ascites display altered immune environment featured by enhanced soluble factors and suppressive cellular context

Background The tumor microenvironment of epithelial ovarian cancer is unique among solid tumors, as tumor cells can shape their own microenvironment through the formation of malignant ascites. These ascites represent a complex mixture of soluble factors and cellular components. They are known to be enriched in macrophages, which have been suggested to acquire an M2-like […]
