Additional Information
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).
