La inducción de la tolerancia al aloinjerto sigue siendo una meta por alcanzar en el trasplante de órganos. La mayoría de las estrategias terapéuticas se centran en la inhibición del sistema inmunológico adaptativo, pero datos recientes demuestran que el reconocimiento alogénico de las células mieloides inicia el rechazo al trasplante. Terapias dirigidas hacia las células mieloides “in vivo” representan un objetivo potencial para inducir tolerancia inmunológica, pero permanece inexplorado clínicamente.Nuestro laboratorio utiliza una nanoinmunoterapia revolucionaria de nanopartículas de lipoproteínas de alta densidad (HDL) cargadas con rapamicina (mTORi-HDL) que previenen las modificaciones epigenéticas asociadas con la inmunidad entrenada, un estado funcional de los macrófagos recientemente descubierto. Usando un modelo experimental de trasplante en ratón, nuestros resultados demuestran que la administración de esta inmunoterapia con mTORi-HDL previene la respuesta inmunológica y promueve la tolerancia al órgano trasplantado.Nuestro laboratorio muestra un enfoque de investigación multidisciplinar articulado en tres objetivos diferentes para evaluar la relevancia clínica y los efectos terapéuticos de la inmunoterapia como preparación para un ensayo clínico en trasplante de órganos. Los objetivos generales estarán orientados a confirmar la identificación de la inmunidad entrenada como biomarcador y valor analítico para predecir el riesgo de rechazo en pacientes trasplantados bajo tres condiciones: periodos prolongadas de reperfusión isquémica (IRI) (objetivo 1), alosensibilización (objetivo 2) e infección (objetivo 3).

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).
