Sub-clustering of the mononuclear phagocyte cells (MPC), revealed 9 distinct cell sub-populations differently modified with RM. One macrophage cluster was particularly interesting since it behaved as a critical node in a trajectory connecting one MCHIIhigh cluster only present in control to 2 MCHIIlow clusters only present in RM-AKI. This critical cluster expressed a senescence gene signature, that was very different from that of the TECs. Senolytic DQ treatment blocked the switch from a F4/80highCD11blow to F4/80lowCD11bhigh phenotype, which correlated with prolonged nephroprotection in RM-AKI.nnCONCLUSIONS: scRNASeq unmasked novel transitional macrophage subpopulation associated with RM-AKI characterized by the activation of cellular senescence processes.

A combination of senolytics (dasatinib and quercetin, DQ) was administered to mice exposed or not to RM-AKI.nnRESULTS: Unsupervised clustering of nearly 17,000 single-cell transcriptomes identified 7 known immune cell clusters. Sub-clustering of the mononuclear phagocyte cells (MPC), revealed 9 distinct cell sub-populations differently modified with RM. One macrophage cluster was particularly interesting since it behaved as a critical node in a trajectory connecting one MCHIIhigh cluster only present in control to 2 MCHIIlow clusters only present in RM-AKI. This critical cluster expressed a senescence gene signature, that was very different from that of the TECs. Senolytic DQ treatment blocked the switch from a F4/80highCD11blow to F4/80lowCD11bhigh phenotype, which correlated with prolonged nephroprotection in RM-AKI.nnCONCLUSIONS: scRNASeq unmasked novel transitional macrophage subpopulation associated with RM-AKI characterized by the activation of cellular senescence processes. This work provides a proof-of-concept that senolytics nephroprotective effects may rely, at least in part, on subtle immune modulation. |
