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.

Additional Information

The Medical Entomology Laboratory has accumulated extensive experience in this field, especially in entomological field studies, biology of arthropods of medical interest, vector competence and vector control. Also, in the molecular detection of Leishmania infantum promastigotes in naturally parasitized phlebotomine sand flies, in the molecular identification of blood ingested by hematophagous arthropods and in the study of the immunomodulatory properties of proteins present in the saliva of phlebotomine sand flies and mosquitoes. Our laboratory is currently co-leading the studies of vectors and wild reservoirs of leishmaniasis in the leishmaniasis focus of Fuenlabrada, Madrid. In this sense, we have studied the role of asymptomatic individuals as reservoirs in the outbreak by xenodiagnosis. On the other hand, we have participated since 2007 in the Entomological Surveillance Program in Airports and Ports against Potential Vectors of Exotic Infectious Diseases, a program that is allowing to develop the expansion map in Spain of Aedes albopictus. In 2016-2017, we carried out surveillance of Ae. albopictus in the Community of Castilla-La Mancha. On the other hand, we conducted studies on the role of patients with post-kala-azar dermal leishmaniasis (PKDL) in the transmission of the parasite in Bangladesh and Sudan. In addition, we participate in research studying ticks transmitting Crimean-Congo hemorrhagic fever in Spain.

Currently, it maintains confidentiality agreements with several companies participating in the evaluation of molecules with activity against pathogens in vectors (GSK), in the development of vector traps using artificial intelligence algorithms (Irideon, Spain), and in the evaluation of repellents against phlebotomine sand flies (IRSEA, France).

The laboratory actively participates in outreach activities such as the Science Week or the European Researchers' Night, among others, making medical entomology science available to the general population.

The Medical Entomology Laboratory has accumulated extensive experience in this field, especially in entomological field studies, biology of arthropods of medical interest, vector competence and vector control. Also, in the molecular detection of Leishmania infantum promastigotes in naturally parasitized phlebotomine sand flies, in the molecular identification of blood ingested by hematophagous arthropods and in the study of the immunomodulatory properties of proteins present in the saliva of phlebotomine sand flies and mosquitoes. Our laboratory is currently co-leading the studies of vectors and wild reservoirs of leishmaniasis in the leishmaniasis focus of Fuenlabrada, Madrid. In this sense, we have studied the role of asymptomatic individuals as reservoirs in the outbreak by xenodiagnosis. On the other hand, we have participated since 2007 in the Entomological Surveillance Program in Airports and Ports against Potential Vectors of Exotic Infectious Diseases, a program that is allowing to develop the expansion map in Spain of Aedes albopictus. In 2016-2017, we carried out surveillance of Ae. albopictus in the Community of Castilla-La Mancha. On the other hand, we conducted studies on the role of patients with post-kala-azar dermal leishmaniasis (PKDL) in the transmission of the parasite in Bangladesh and Sudan.
