Exercise Training and Kidney Transplantation

The goal of this clinical trial is to investigate the physiological and molecular effects of exercise training in transplant recipients. The main questions it aims to answer are: 1. Can exercise training improve physical fitness and muscle strength in transplant recipients? 2. Can exercise training modulate inflammatory profile, hormones, lipid profile, and exercise-induced molecules in transplant recipients? 3. Can exercise training improve blood pressure and endothelial health in transplant patients? Participants will be invited to an exercise training program 6-month after their transplant surgery. Body composition, physical assessment, and blood draw will be assessed at baseline and 24-weeks after exercise or control regimen. Researchers will compare exercise group vs. routine care group to see if exercise training impact the health-related outcomes of this population.

Phase I Trial on the Safety of Delayed Infusion of a Naïve T Cell-Depleted Hematopoietic Graft With Memory T Cells in Solid Organ Transplant Recipients

The goal of this clinical trial is to evaluate the safety and feasibility of inducing hematopoietic mixed chimerism to promote immune tolerance and potentially reduce the need for lifelong immunosuppression in pediatric and adult patients undergoing solid organ transplantation (SOT), including kidney, lung, and multivisceral transplants. The main questions it aims to answer are: * Is it safe to infuse a naïve T cell-depleted hematopoietic graft along with memory T-lymphocytes after SOT? * Can this approach support immune tolerance and reduce the incidence of rejection and infection without long-term immunosuppression? Participants will: * Undergo a solid organ transplant from a living or deceased donor. * Wait through a stabilization period to ensure resolution of early transplant-related complications. * Receive low-dose preconditioning (TLI and thymic irradiation) to prepare for hematopoietic stem cell transplantation. * Be infused with a graft containing CD34+ progenitor cells, memory T cells (CD45RO+), and no naïve T cells (CD45RA+); in some cases, NK cells may also be included. * Be followed for graft survival, immune tolerance, infection rates, and adverse events through regular clinical and immune monitoring visits.
