Modulation of Acid Sphingomyelinase in Melanoma Reprogrammes the Tumour Immune Microenvironment by Emma Assi, Davide Cervia, Laura Bizzozero, Annalisa Capobianco, Sarah Pambianco, Federica Morisi, Clara De Palma, Claudia Moscheni, Paolo Pellegrino, Emilio Clementi, Cristiana Perrotta

“…We found high levels of inflammatory factors in low A-SMase expressing tumours, which also displayed an immunosuppressive/protumoural microenvironment: high levels of myeloid-derived suppressor cells (MDSCs) and regulatory T lymphocytes (Tregs), as well as low levels of dendritic cells (DCs). In contrast, the restoration of A-SMase in melanoma cells not only reduced tumour growth and immunosuppression, but also induced a high recruitment at tumour site of effector immune cells with an antitumoural function. …”
