Experimental Tuberculosis Unit (UTE)
Pere Joan Cardona
The Unitat de Tuberculosi Experimental (Experimental Tuberculosis Unit, UTE), was founded by Dr. Pere-Joan Cardona in 1997. It is located in the Can Ruti Campus as a unit of the IGTP and it is part of the Clinical and Experimental Research Group (2009 SGR 1485, led by Pr. V. Ausina) and the CRP-TB Consortium of the CIBERES net, funded by the Spanish Government; and linked to the University (Microbiology and Genetics Department, Faculty of Medicine, Universitat Autonòma de Barcelona).
Experimental modeling of TB
PI: Dr Pere-Joan Cardona
This research line is devoted to the design, develpment and characterization of new experimental models (in vitro, in vivo and in silico) to a) study and better understand TB course: TB infection and progression to active disease; b) to better mimic TB in humans; and c) to study the influence of comorbidities in TB (as does within the H2020 EU-funded Consortia TBVAC2020 (Grant nº643381)).
Evaluation of new prophylactic and therapeutic strategies against TB
PI: Dr Pere-Joan Cardona
The study of the immunopathology of the TB infection led Dr. Cardona to propose a new hypothesis (the Dynamic Hypothesis) to explain the Latent Tuberculosis Infection, and the design, patent and development of RUTI®, a therapeutic vaccine to shorten the chemotherapy of latent tuberculosis infection. RUTI® was evaluated in a successful Phase II Clinical Trial in SouthAfrica, and has also proved both a prophylactic and a post-exposure effect, generating 2 other patents. The vaccine was fully transferred to the biotech company named Archivel Farma S.L. for its manufacture under GMP conditions and further clinical development. Archivel Farma was created by created as a spin-off of the IGTP by Dr. Pere-Joan Cardona, and he was its scientific director during many years. Thanks to the RUTI® project, the UTE has become an international reference to evaluate new prophylactic and therapeutic strategies, particularly vaccine candidates, being contracted by several institutes and biotech & pharma companies (Archivel Farma S.L., Grup Ferrer, GlaxoSmithKline); and included in several international consortia ("Preclinical and clinical evaluation of a post-exposure TB vaccine" Consortium, funded by the Bill and Melinda Gates Foundation GC#12; and 3 european consortia funded by the 7th Framework Program of the EC (STOPLATENT-TB (200999), NEWTBVAC (241745) and NOPERSIST (FP7-SME-2008-1, 232188)).
Depending on the final aim of the contractor, we can provide a wide portfolio of experimental animal models and services to evaluate prophylactic/therapeutic strategies against Tuberculosis, including:
- Effect on survival in a SCID murine model (safety-efficacy): Toxicity model for attenuated vaccines
- Effect on survival and bacillary load in an active TB murine model (modified-Kramnik model in C3HeB/FeJ mice): Prevention of infection, Prevention of disease, Containment of Latent Tuberculosis
- Effect on the bacillary load in an acute infection murine model: Prevention of infection
- Effect on the bacillary load in a latency murine model: Immunotherapeutic application
- Effect on the lesion dissemination (through High-resolution scanner (TAC) and histology-histometry) and bacillary load in a latency model in minipigs: Immunotherapeutic application
- Effect on survival and bacillary load in a Multiple Consecutive Infections murine model: Prevention of infection, Prevention of disease, Containment of Latent Tuberculosis
- Histometry analysis of the effect of vaccine candidates in pathology lung samples
Nyaditum resae® (NR) Project
The recent research of the UTE on the evolution from latent infection towards active tuberculosis and the role that inflammation has in it, has led to a new patent and the creation of a new spin-off, Manresana de Micobacteriologia (MANREMYC) for the development of a new therapeutic strategy against TB, a food supplement called Nyaditum resae®. Dr Cardona is the CEO/CSO of this spin-off. For more info please see the Manremyc website.
Study of the role of inflammation in TB and its modulation through Host-Directed Therapies (HDT)
PI: Dr Cris Vilaplana
This research line was created thanks to the Miguel Servet 1 personal contract awarded to Dr. Vilaplana (CP13/00174), and includes:
- Study of TB lesions obtained in surgery: in search of best biomarkers correlating with TB pathology, clinical features, MDR cases and prognostic. In collaboration with the National Center of Tuberculosis and Lung Diseases (NCTLD) of Georgia
- Evaluation in animal models and in clinical trials of repurposed drugs with anti-inflammatory effect (mainly common NSAIDs as ibuprofen and aspirin, statins and others). This project has allowed the UTE to be part of the collaborative network Africa-Europe Host-Directed Therapies Network (HDT-NET)
One of the main aims of the Unit is to collaborate and promote training and dissemination activities. The UTE has trained many people in animal experimentation, research on tuberculosis, vaccine development, knowledge & technology transfer and innovation. We continuously accept degree, masters and other students from very different fields (medical, biomedic, physics, bioengineering), and we often have open PhD positions. Please do not hesitate to check our blogsite from time to time and sending an email for vacancies or other opportunities.
The Unit has organized three successful international Symposia and we are now organizing a TB meeting in Empúries (L'Escala, Costa Brava, Catalonia): "Correlating Clinical and Experimental Pathology" (8-10th June 2016, in collaboration with the TBVI) with the aim to gather basic researchers and clinicians to discuss the contribution of experimental animal models in the TB research field, and how experimental animal models could better mimic human disease.
Study of the mechanisms implicated in protection againt tuberculosis generated by low doses of inacativated microbacteria
Objetivos: 1.- Evaluación de la capacidad de las Treg específicas generadas con pautas de dosis bajas de micobacterias ambientales inactivadas de bloquear la respuesta Th17; 2.- Evaluación de condiciones ambientales (administración de vitaminas A y/o D) que favorecen la estimulación de Tregs a nivel intestinal. 3.- Evaluación de la eficacia de Tregs en circunstancias de comorbididad relacionadas con la transmisión y desarrollo de la TB en humanos; 4.- Importancia de la microbiota en el desarrollo de una respuesta Treg eficaz.
