Introduction: Tumour microenvironment (TME) is determined by non-tumoral cells, including immune, stromal or endothelial cells, and influences tumorigenesis, proliferation, invasiveness and angiogenesis. Little is known about TME in pituitary adenomas (PAs). We aimed to characterise the TME of PAs and its role in their aggressiveness, focusing on PA-infiltrating immune cells and cytokine network.Methods: Cytokine secretome from 24 human PAs (16NFPAs, 8GH...

Introduction: Angiogenesis is regulated by different components of the tumour microenvironment (TME) including cytokines and immune cells. Although angiogenesis has been studied in pituitary adenomas (PAs), the role of individual TME components in PA angiogenesis remains largely unknown. We aimed to characterise the role of the TME components in determining the angiogenesis of PAs, focusing on PA-infiltrating immune cells and the PA-derived cytokine network.<p class="abste...
