Salvador Martinez (MD, PhD and Professor of Anatomy) is analyzing the role of pericytes (perivascular cells) in the control of the immune response against glioblastoma multiforme. This study is describing the cellular and molecular mechanisms underlying the immune tolerance of this type of cancer (Valdor et al., Oncotarjet, 2017, PNAS, 2019; Molina et al., Cancers 2019, Front Cel Biol 2022; Pombero et al., 2023), demonstrating the cellular mechanisms underlaying tumor immunosuppression.
