Alterations in glycosylation in tumours facilitate tumour progression. Here, the authors show that pancreatic ductal adenocarcinomas present increased sialylation, which stimulates the polarisation of monocytes via Siglec receptors, resulting in the generation of immune suppressive tumour associated macrophages.
