The Immunobiology group has been working for years on the following lines of research:
1) The mechanisms of haematopoietic cell generation throughout ontogeny and the influence that the first haematopoietic cells exert on the innate and adaptive immune system present in the adults. We have identified and characterised a new population of B lymphocytes called B1-Rel (B220lo), which produce high levels of natural IgG/IgA antibodies. We sought to understand their role in the immune response in animal models of infection, analysing their impact on immune cell populations and on the production of soluble mediators (cytokines and immunoglobulins). In this regard, we have evaluated the generation of embryonic megakaryocytes (and their differentiation niches), their functionality and that of platelets, and their influence on haematopoietic development. For lymphoid populations, we have carried out extensive characterisation by flow cytometry and single cell RNA sequencing (scRNAseq) methodology. To carry out these cellomic studies, we have designed complex panels for use in multiparametric phenotypic analysis, and single cell cytometry and RNAseq omics technologies on purified cell populations.


In parallel, we are interested in understanding local immune responses in respiratory infections at times of particular susceptibility due to the fragility of the immune system (childhood and old age), both in mouse animal models, which allow their manipulation, and in humans. 

2) Mouse models studied during neonatal life, in which we evaluated the effect of antibiotic (AB) treatment and addressed the role of TLR receptors in innate, pseudo-innate and adaptive immune cell populations. In these models, we observed that AB administration was able to modulate B-lymphoid populations, as well as their ability to secrete proinflammatory cytokines in culture and their differentiation into plasma cells, with differentiated immunoglobulin repertoires. Furthermore. These effects were mediated through the Toll-like receptor-2 (TLR2).

3) Mouse models with accelerated senescence (SAMP8) and senescent animals (over 20 months of age) to map lymphoid populations and soluble mediators of the immune response (immunoglobulins and cytokines). In these models, the B lymphoid populations (B1Rel and marginal zone B lymphocytes) are observed to be altered, accompanied by an increase in IgG1 with great restriction of their VDJ repertoires.


4) Role of the B1Rel population in animal models of local or systemic infection. We analysed the response to Streptoccoccus pneumoniae (SPN) locally in the lung and systemically in the spleen, as well as the role of TLR4 in these responses.

5) In humans, we are studying immune responses in children with respiratory syncytial virus (RSV) viral primo-infection. In this case we studied the immune response that occurs locally in the nasal mucosa (by analysis of nasal washings, NW) in a cohort of infected children versus healthy controls, stratified by age. We found that lymphomyeloid cells accumulate in these nasal washings in patients with diverse lymphocyte populations, as well as cytokines and immunoglobulins.

6) Analysis and characterisation of extracellular vesicles produced during respiratory infection both in lung supernatants from models of SPN infection and in LN in the case of children with RSV infection.

7) In parallel, we carry out studies of the genetic rearrangements of immunoglobulins and their use in the generation of chimeric receptors for possible use in immunotherapy.

The researchers of the Viral Infection and Immunity Unit (UIVI) are part of the CIBER de Infectious Diseases (CIBERINFEC) as an independent group (https://www.ciberinfec.es/grupos/grupo-de-investigacion?id=27501).  The UIVI studies the immunopathology of clinically relevant infections in humans, such as chronic viral hepatitis (Hepatitis B, C and D), HIV, and SARS-CoV-2, and their impact on the clinical evolution of infected patients. We also analyse the evolution of the patient after controlling viral replication or after eliminating the virus spontaneously or by antiviral treatment.

The group focuses mainly on translational research in which collaborating clinical groups also participate. On the one hand, ‘omics’ techniques such as genomics, transcriptomics, proteomics, metabolomics, epigenetics and metagenomics are used, which, depending on the type of study, are targeted or not. On the other hand, specific laboratory assays designed in-house, such as PCR, RT-PCR, immunoassays for virus titration and neutralisation, production of monoclonal antibodies, among others, are carried out. With the molecular data obtained from patient samples, we perform bioinformatics/statistical analyses, analysing their association with the clinical condition of the patients and their subsequent evolution. 

The current director of CNM is Dr. José Miguel Rubio Muñoz.

Dr. José Miguel Rubio has a degree in Biological Sciences from the Universidad Autónoma de Madrid (1986) and a PhD in Biological Sciences from the same university (1992). He carried out his doctoral thesis at the Department of Genetics of the Universidad Autónoma de Madrid, as Associate Professor (1988-1989), and at the School of Biology of the University of East Anglia in Norwich, UK, as Senior Research Assistant (1989-1992).

During his postdoctoral period he obtained a grant from the European Commission within the Human Capital and Mobility Program to be carried out at the University of “La Sapienza” in Rome, Italy and the Institute of Molecular Biology and Biotechnology in Crete, Greece (1993-1994). Subsequently, he made a further stay funded by the WHO and the university itself at the Department of Entomology, Wageningen University, The Netherlands (1994-1996).

Since 1997 he has been a member of the Instituto de Salud Carlos III (ISCIII), where he joined the Department of Parasitology of the National Center of Microbiology, as an EU-INCO postdoctoral fellow and later with a grant from the Autonomous Community of Madrid (CAM). She was part of the founding group of the National Center for Tropical Medicine (2003-2006) and of the 24/7 Alerts and Emergencies Unit (2006-2018) and is currently Head of the Malaria and Emerging Parasitosis Unit of the National Microbiology Center and is part, as research staff, of the Center for Biomedical Research Network on Infectious Diseases (CIBERINFEC/ISCIII).

During his scientific career he has been Visiting Scientist at the Leonidas e Marie Dean Center (FIOCRUZ-AMAZONAS, Manaus, Brazil) and is an External Consultant of the Parasitology Departments of Cairo University (Egypt) and the Medical Research Center (MRC) of Kuala Lumpur (Malaysia).  He also belongs or has belonged to different national and international committees:  Member of the expert group for malaria control of the European Centre for Disease Control (ECDC) since 2011; Expert-Evaluator for health programs of the European Commission since 2004; Spanish Representative (commissioned by ISCIII and MSC) in the Technical Scientific Committee of the TDR (WHO) 2007-2008; Spanish Deputy Focal Point for microbiology at the European Centre for Disease Control (ECDC) from 2012 to 2020; and, member of the Research Ethics Committee of ISCIII until 2019.

In this period he has published more than 100 articles in international indexed journals, 10 book chapters and has been co-editor of two books in the area of malaria, tropical medicine and neglected diseases. He has participated in 58 competitively funded research projects, 20 of them international, having been the principal investigator in 8 national and 11 international projects as PI of the project or WP leader. In addition, he has led five agreements with companies. Currently he has been awarded four sexenios of research, being presented this year 2025 to the fifth. In the teaching field, he participates in different postgraduate programs in the areas of microbiology and parasitology, having directed seven doctoral theses and more than 20 Master's or Degree final projects, both nationally and internationally. ​​​​​
