Rejection of allogeneic tissues and organs is an immunological phenomenon mediated by T cells and antibodies. The rejection of transplanted vascularized solid organs across MHC histocompatibility barriers requires continuous and prolonged use of immunosuppressive drugs, which are responsible for long-term serious side effects. Therefore, those therapeutic interventions or strategies to reduce or ideally eliminate immunosuppressive medication that allow the induction of immunological tolerance would achieve long-term graft survival and the improvement in the quality of life of transplanted patients.
The final goal of our laboratory is the identification and validation of molecular targets essential for the exchange of information between dendritic cells / T cells and T/ B cells for the modulation of the allogeneic humoral and cellular mediated immune responses.
1) Prevention of allograft rejection by interfering with the collaboration of dendritic cells / B / T cells through blockade of costimulatory signals or the enhancement of negative signaling to T cells (coinhibitory signals).
2) Prevention of rejection by the selective elimination of T cells responsive to alloantigen, targeting molecules that are restrictively expressed upon T cell activation.
To address these objectives, we applied biochemical techniques, molecular biology, cellular and animal models of skin and bone marrow transplantation. We amplify genes of interest involved in particular pathways of cell interaction, which are then cloned and expressed as membrane bound proteins and soluble proteins (extracellular regions). Soluble recombinant proteins are purified from culture supernatant of transfected cells and use as antigens for the generation of antibodies with different effector functions (agonist, antagonist, depleting, non-depleting). Finally, these antibodies and recombinant proteins are used as therapeutic tools in vitro and in vivo to test their efficacy in preventing allogeneic immune responses across different histocompatibility barriers to dissect the mechanisms involved in graft rejection and tolerance.
The ultimate goal of the lab is to prove that the experimental strategies developed in the course of our studies are able to prevent rejection in in vivo animal models of skin and bone marrow transplantation across different MHC histocompatibility barriers , where the rejection response is mediated by CD4 and CD8 T lymphocytes and anti-donor specific antibodies.
