Using Scientific Registry of Transplant Recipients data on adult, first-time, non-Status1A, period-prevalent waitlist candidates, we conducted multilevel Poisson regression with center-level and DSA-level intercepts to model DDLT rates across 3 eras: preacuity circles (pre-AC) (May 1, 2017 to April 30, 2019), initial post-AC (February 4, 2020 to February 3, 2022), and recent post-AC (February 4, 2022 to December 31, 2024), adjusting for candidate factors. We calculated center-level and DSA-level median incidence rate ratios (MIRRs) and their relative contributions to total geographic variation. DSA-level MIRR declined from _1.471.52_1.58 to _1.321.37_1.42 to _1.171.23_1.28 from pre-AC to initial post-AC to recent post-AC.

Here, we showed that under minimal effector T cell (Teff) response settings, Treg were unexpectedly inefficient at migrating to inflamed allografts despite circulatory presence. In contrast, Teff infiltration into inflamed allografts induced a multifold increase in intragraft Treg accumulation. These observations were confirmed in 2 lymphoreplete murine models in which Treg trafficking can be assessed with or without concurrent Teff activity. Intravital microscopy revealed that although Treg transferred alone remained confined to perivascular spaces, the presence of Teff enabled Treg migration deep into graft tissue. Mechanistically, Teff increased graft inflammation, and Teff-driven Treg migration to allografts required chemokine receptor signaling in Treg. In addition, we demonstrated that Teff-conditioned media directly promoted chemokine receptor-dependent Treg transmigration in vitro.

Analysis of human liver graft samples revealed the clinical association of CD38-related nicotinamide adenine dinucleotide (NAD)⁺ dysregulation with transplantation-associated injury, although mechanistic investigations using mouse models and macrophage systems identified the CD38-NAD⁺-sirtuin 1(SIRT1)-estrogen-related receptor (ERR)α-NLRP3 pathway underlying aging-associated IRI.

Importantly, innate immune memory may influence alloimmune responses by shaping adaptive T cell activation through altered cytokine production, antigen presentation, and costimulatory signals.
