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 of the Spanish Government (ISCIII) and the AGAUR Research Quality Group 2021-SGR- 01186.

The group is conducting 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 developing new therapies that modulate their responses. In this context, tehir interests are at present mostly centred on the role of macrophage protein CD5L in the control of immune homeostasis and inflammatory disease.

Keywords: Liver, cancer, infection, macrophage, CD5L.

Innate Immunity research group

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, with a focus on Mycobacterium tuberculosis

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.

Nova immunoteràpia dirigida a macròfags tumorals per abordar el càncer de pulmó

Investigadors del grup d'Immunitat Innata de l'Institut de Recerca Germans Trias i Pujol (IGTP) han desenvolupat una nova immunoteràpia basada en un anticòs monoclonal dirigit contra macròfags tumorals. Els resultats obtinguts estableixen les bases d'un nou tractament per a pacients amb càncer de pulmó, amb el potencial d'aplicar-se en altres tumors sòlids. L'estudi s'ha publicat a la revista eBioMedicine.
