Sonia Andrea León-Cabrera, PhD, is a faculty member at the Facultad de Estudios Superiores Iztacala, National Autonomous University of Mexico (UNAM), where she leads the Tumor Immunity Laboratory at the Unidad de Biomedicina (UBIMED). Her research focuses on tumor immunology, colorectal cancer, inflammation-associated carcinogenesis, and the mechanisms by which immune and dietary signals shape the tumor microenvironment. Her work has particularly addressed the role of STAT6 signaling in cancer progression and immune regulation, as well as the stability and therapeutic potential of regulatory T cells. More recently, her group has investigated how non-nutritive sweeteners such as sucralose affect intestinal homeostasis, gut barrier integrity, and antitumor immunity. Her laboratory integrates murine models, cellular and molecular immunology, histopathology, and translational analyses of human samples to identify mechanisms linking inflammation, immune dysfunction, and cancer progression. She is interested in national and international collaborations in tumor immunology, colorectal cancer, mucosal immunology, and translational cancer research.
