About
The Innate Immunity Group, established in 2009, is focused on the study of innate immunity in health and disease. The team is located at IGTP and is part of the CIBERehd Consortium Group CB06/04/0033 and the AGAUR Research Quality Group 2021-SGR-01186.
The group conducts research on three important aspects of human pathology: liver disease, cancer and bacterial infection.
The aim of its researchers is to define the role of innate immunity proteins as prognostic or diagnostic biomarkers of disease. They are also engaged in the study of macrophages as central drivers of innate immunity and as targets for therapeutic intervention. In this context, their interests are currently mostly centered on the role of macrophage protein CD5L in the control of immune homeostasis, inflammatory disease and cancer.
Keywords: Liver, cancer, infection, macrophage, CD5L, immunotherapy.

Maria Rosa Sarrias, PhD
Maria-Rosa Sarrias has a PhD in Biochemistry and Molecular Biology from Universitat Autònoma de Barcelona. Her academic track includes a 5-year stay at the University of Pennsylvania, USA, followed by a post-doctoral position at the Immunology Department of Hospital Clínic of Barcelona. In 2009, she secured a Miguel Servet Fellowship, enabling her to establish the Innate Immunity Group at IGTP, where she currently serves as a consolidated researcher.
Sarrias has dedicated her career to understanding innate immunity. Her journey into this fascinating field began by exploring the body's innate ability to defend itself against pathogens and prevent sepsis through the complement system and scavenger receptors. As a group leader, she has focused on macrophages, because these are central cells of innate immunity; their abundancy, plasticity and multiplicity of actions make them a very attractive cell type for study and therapeutically target. Consequently, her group is at present dedicated to studying the role of macrophages in various inflammatory-driven diseases. Their work in recent years, particularly in the fields of infection and cancer, has contributed to defining new biomarkers and is leading to the development of a novel therapeutic strategy for clinical intervention in cancer.

Research lines
Role of innate immunity in liver disease
The group is exploring the potential of several innate immunity proteins as biomarkers for the improvement of patient management and for the better understanding of the complex mechanisms underlying liver disease.
Novel cancer immunotherapy strategy targeting macrophages
Macrophages are the most abundant immune cells in tumors, and since they are immunosuppressive in most solid cancers, they are a promising cell target in immuno-oncology. The team is developing new immunotherapies based on monoclonal antibodies directed against tumor macrophages.
Role of macrophage protein CD5L in infection
The innate immune response is the first line of defense against invading pathogens. The group is devoted to understand the complex interplay between host defense and pathogen evasion. Its studies include the role of CD5L in modulating macrophage responses to bacterial products, from inflammatory molecules (eg LPS) to whole organisms, such as Escherichia coli or Mycobacterium tuberculosis. This research line opens the door to the discovery of new therapeutic targets.

Collaborative networks
- COST ACTION CA 20117: Converting Molecular Profiles of Myeloid Cells into Biomarkers for Inflammation and Cancer. Mye-InfoBank utilises COST networking tools to enable the interaction of molecular biologists, bioinformaticians, immunobiologists, biobank coordinators and clinicians. The concerted activity of these experts on myeloid cell biology (either basic or clinical research) MYE, bioinformatics INFO, and bio-banking BANK, transforms complex molecular information into standardised and applicable biomarkers, which have the potential to improve clinical decision making in a number of socio-economically important diseases.
- CIBEREHD: Biomedical Research Network Center. Liver and Digestive Diseases CB06/04/0033, Group 3. The group studies the microenvironmental interactions between macrophages and stellate cells and hepatocytes in the context of liver disease. They are also exploring the potential of several innate immunity molecules as therapeutic targets or biomarkers of pathology. With both approaches, they aim to improve our understanding of the complex mechanisms underlying liver disease.
