Celia López-Sanz
I completed a BSc in Biochemistry at the Universidad Autónoma de Madrid (Spain) in 2018, and I am currently an Immunology Intern at the Hospital Universitario de La Princesa.
I took my first steps in science in the last year of college, when I performed my end-of-degree project about the pre-TCR signaling pathway and its possible implication in T acute lymphoblastic leukaemia (T-ALL) at the Centro de Biología Molecular Severo Ochoa (CBMSO).
After that, I started my studies in the clinical setting and I am currently working as an Immunology Intern at the Hospital Universitario de La Princesa. In the course of my internship the multidisciplinary research caught my attention. For that reason, I got interested in Dr. Jiménez-Saiz’s research lines and decided to begin my PhD in his group.

Lucía Moreno Serna
I graduated in Biotechnology in 2021 at the CEU San Pablo University (Madrid) where I did my end-of-degree project about the viability of viruses in contact with face masks. After that, I spent three months in the University of Natural Resources and Life Sciences (Austria, Viena) collaborating to improve the protein production in Pichia pastoris yeast.
Furthermore, I took a Master's degree in Microbiology applied to Public Health and Infectious Diseases research in Alcalá de Henares University (Madrid). My master's thesis was focused on Study of the infective capacity, morphology and movement and phagocytic capacity of macrophages after the use of three tyrosine kinase inhibitors (imatinib, dasatinib and ponatinib) compared with a baseline in HIV. It was carried by the AIDS Immunopathology department of Instituto de Salud Carlos III (Madrid).

Elisa Sánchez Martínez
I graduated in Biology in 2022, at the Universidad Complutense de Madrid (UCM, Spain) and in 2023 I got my master´s degree in immunology at UCM.
I have been interested in different projects related to nutrition and antibiotic resistance. Hence, I participated in activities related to this topic organized by the Consejo Superior de Investigaciones Científicas (CSIC, Spain) and collaborated with the Small World Initiative (SWI) Project. In summer 2022, I participated in a cross-European team as part of the Una Europa One Health Summer School at the University of Edinburgh.
I met Dr. Jiménez-Saiz doing biochemistry laboratory, which prompted me to choose his group for beginning to develop myself as a scientist. I performed my end-of-degree project about mast cell immunomodulation with his group. Currently, I am starting my predoctoral career continuing the research line about the impact of microbiota in Th2 immune responses.

Paula H. Ruiz de Azcárate
I graduated in Biotechnology in 2020, at the University of Barcelona (Spain). I went to the University of Padua (Italy) to develop my end-of-degree project. It was focused on cellular bioenergetics in the pathways of mitochondria and Ca2+ tethering. We were also developing a new organelle proximity sensor (SPLICS).
Then, I took a Research Master in Translational Medicine, specialized in neurologic diseases at UCM (Spain). My end-of-master project was carried at the Neuroscience and Mental Health Dept. of the 12th of October Hospital (Dr. Bartolome´s lab). It was focused on SORL1 mutation in humans with Alzheimer’s Disease.
Now, I am studying a Master in Clinical Trials Monitoring at CESIF; but as I want to follow the research pathway I started looking for a laboratory that centers its attention on translational research and joined Dr. Jimenez-Saiz’s lab.

I graduated in Health Biology at the Alcalá de Henares University (Spain) in 2017. During this year, I did my end-of-degree project at the Centro de Investigaciones Biológicas (CIB) where I preclinically evaluated different cannabinoid compounds to treat Alzheimer's disease.
Subsequently, I did the Master in Immunology Research at the Complutense University of Madrid (UCM, Spain) in 2018. In turn, I carried out my end-of-degree project at the Immunoallergy and Proteomics laboratory of the IIS-Fundación Jiménez Díaz Hospital (Spain), where I studied the molecular basis of anaphylaxis and other allergic diseases. In this laboratory, I developed my doctoral thesis on circulating proteins, extracellular vesicles and microRNAs in anaphylaxis, which I defended at the UCM in 2023. In addition, I did a 3-month fellowship in 2022 at the Bambino Gesù Pediatric Hospital (Italy). Currently, I am working at Dr. Rodrigo Jiménez Saiz's lab thanks to a Sara Borrell contract from ISCIII.

Research
Our goal is to understand immunological principles of type 2 immunity in the context of allergic disease, particularly as it pertains to acute allergic reactions and its modulation by the microbiota, mast cell-neuron communication, and the impact of allergic disease in the development of atherosclerosis.
Our lab has a marked translational identity, which has been achieved through research in pre-clinical models of allergic disease and a close collaboration with clinicians.
We are constantly seeking for new members that are highly motivated and have strong critical thinking skills!
