Exploring kidney transplant tolerance using blood samples
Non-interventional Single-center Study of the Contribution of DP8α Regulatory T Cells Induced by a Gut Microbiota Bacterium to Kidney Transplant Tolerance.
This study looks at blood samples from kidney transplant patients to see if certain immune cells can help prevent the body from rejecting the new kidney.

What this trial studies
This observational study aims to investigate kidney transplant tolerance by analyzing peripheral blood mononuclear cells (PBMC) from adult donor-recipient pairs treated at Nantes University Hospital. The study will focus on the role of DP8α regulatory T cells expressing CD73, which are hypothesized to be involved in preventing transplant rejection. Blood samples will be collected during routine clinical visits to assess the frequency of these Tregs and their potential donor-specific characteristics. The goal is to understand how these immune cells contribute to tolerance in kidney transplants.
Who should consider this trial
Good fit: Ideal candidates include adult patients undergoing their first or second kidney transplant from a related living donor with a BMI under 35.
Not a fit: Patients with ABO incompatibility or a BMI over 35 may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved strategies for preventing kidney transplant rejection, enhancing patient outcomes.
How similar studies have performed: While the specific approach of this study is novel, similar studies exploring transplant tolerance have shown promising results in the past.
