The Laboratory of Medical Entomology (LME) develops an intense reference and research activity, focused on the field of disease vectors of interest in Public Health. The LME has an insectary where biological cycles of insect vectors are currently maintained, allowing the performance, among others, of vector competence and xenodiagnostic studies. The LME supports the national health system by offering techniques available in the portfolio of services for the taxonomic identification of arthropods of health interest. In addition, it performs entomological surveillance of outbreaks, supporting Surveillance Plans. In particular, the LME plays a leading role in the Entomological Surveillance Plan for Leishmaniasis in the Community of Madrid. On the other hand, the LME offers scientific advice to the CCAES (Centro de Coordinación de Alertas y Emergencias Sanitarias, Ministerio de Sanidad, Consumo y Bienestar Social), and participates in the elaboration of reports and rapid risk assessments.
The main research lines of the Laboratory of Medical Entomology are:
1. Maintenance of insect vector colonies: phlebotomine sand flies (Phlebotomus perniciosus, Phlebotomus papatasi and Phlebotomus argentipes, vectors of Leishmania infantum, Leishmania major and Leishmania donovani, respectively), Culex and Aedes mosquitoes (vectors of various arboviruses) and Rhodnius prolixus (vector of Trypanosoma cruzi).
2. Biology of disease vectors of public health interest: biology, vector competence, experimental infections. The CNM has a BSL3 safety laboratory to carry out vector competence studies with culicidae and phlebotomine sand flies.
3. Entomological sampling, infectivity of potential reservoirs of leishmaniasis.
4. Insecticides and repellents: evaluation of their efficacy.
5. Characterization of saliva proteins of hematophagous Diptera: genomics, proteomics, biochemistry and gene editing. Study of salivary proteins as markers of bite exposure, virulence factors and/or vaccines.
6. Xenodiagnosis of leishmaniasis.
7. Molecular biology and taxonomy of phlebotomine sand flies. Molecular detection of Leishmania infantum in phlebotomine sand flies and characterization of Leishmania spp. Molecular identification of blood ingested by vectors.

Induction of allograft tolerance remains a goal to be achieved in organ transplantation. Most therapeutic strategies focus on inhibition of the adaptive immune system, but recent data demonstrate that allogeneic recognition of myeloid cells initiates transplant rejection. Therapies targeting myeloid cells “in vivo” represent a potential target to induce immunological tolerance, but remain clinically unexplored.
Our laboratory uses a revolutionary nanoimmunotherapy of high-density lipoprotein (HDL) nanoparticles loaded with rapamycin (mTORi-HDL) that prevents epigenetic modifications associated with trained immunity, a recently discovered functional state of macrophages. Using an experimental mouse transplant model, our results demonstrate that the administration of this immunotherapy with mTORi-HDL prevents the immune response and promotes tolerance to the transplanted organ.
Our laboratory shows a multidisciplinary research approach articulated in three different objectives to evaluate the clinical relevance and therapeutic effects of immunotherapy in preparation for a clinical trial in organ transplantation. The general objectives will be aimed at confirming the identification of trained immunity as a biomarker and analytical value to predict the risk of rejection in transplant patients under three conditions: prolonged periods of ischemic reperfusion (IRI) (objective 1), allosensitization (objective 2) and infection (objective 3).
