Kidney transplant rejection remains a significant challenge to long-term graft survival. While histological biopsy continues to be the gold standard for diagnosing rejection, noninvasive biomarkers such as donor-derived cell-free DNA (dd-cfDNA) have gained traction for their ability to detect allograft injury. However, dd-cfDNA may lack sensitivity in certain clinical scenarios particularly in cases of localized immune activation leading to false negatives despite biopsy-confirmed rejection.

One promising biomarker is CXCL10 (C-X-C motif chemokine ligand 10), a chemokine induced by interferon-γ that plays a central role in recruiting CXCR3+ T cells during immune responses. A 2021 study by Arnau et al. found that urinary CXCL10 levels were significantly associated with Banff scores of acute graft injury and donor-specific antibodies, and could discriminate both T-cell-mediated and antibody-mediated rejection in kidney transplant recipients, identifying CXCL10 as a promising candidate non-invasive biomarker for monitoring allograft rejection.
