Our Research Lines
Cancer
Our work focuses on understanding how interactions between tumor cells and the immune system shape the tumor microenvironment and determine cancer progression and dissemination. In this context, we have recently demonstrated that galectin-1 plays a key role in promoting lung metastases, identifying this lectin as a central regulator of tumor immune evasion mechanisms. These findings suggest that blocking galectin-1–glycan interactions could represent an effective therapeutic strategy for the treatment of metastatic cancer.
In addition, we investigate how steroid hormones modulate the tumor microenvironment and contribute to mechanisms of resistance and immune escape. We also study the role of different immunological populations with tolerogenic functions in regulating tumor progression and metastasis.
The knowledge generated through our research aims to lay the foundation for the development of new therapeutic strategies designed to reverse tumor-induced immunosuppression, overcome treatment resistance, and prevent metastatic dissemination.

Autoimmunity and Inflammation
The interpretation of glyco-codes underlying carbohydrate–galectin interactions, particularly Galectin-1 (Gal1), is a key principle for maintaining homeostasis, promoting the resolution of inflammation, and preventing autoimmune phenomena. Our laboratory has demonstrated that Gal1 acts as an immune checkpoint, shaping the fate of myeloid and lymphoid cells. Its administration, through gene or protein therapy, has been shown in preclinical models to mitigate the clinical manifestations of autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and uveitis, as well as to prevent the development of age-associated inflammation, positioning Gal1 as a promising therapeutic target.
Building on this foundation, our current research focuses on chronic and autoimmune inflammation of the skin, nervous system, and intestine. In these contexts, we map lectin–glycan circuits to understand the mechanisms through which immune balance is disrupted, identify biomarkers and actionable targets, and design therapies aimed at preventing, reversing, or controlling inflammatory processes.
We focus particularly on inflammatory bowel disease (ulcerative colitis and Crohn's disease), multiple sclerosis, and psoriasis. We have demonstrated that Gal1 controls intestinal inflammation in experimental models and are advancing a Gal1 delivery platform designed to enhance local efficacy, reduce adverse effects, enable combinations with existing treatments, and pave the way toward preclinical and clinical validation. At the physiological level, we have also studied these interactions at the maternal–fetal interface.
Our goal is to provide meaningful solutions for individuals whose lives are profoundly affected by these chronic diseases, seeking to mitigate clinical processes, improve patient quality of life, and contribute to a more efficient use of healthcare system resources.
