Activation1
NAD+ decides whether a healing macrophage also turns fibrotic
Where this hypothesis actsAged human macrophages with insufficient SIRT6 activity during SPM-driven M2 polarization
What is proposedRestore SIRT6-mediated histone deacetylation
With whatSmall molecule
HowRestore activity through NAD+ repletion with NMN or NR; test dependence on SIRT6 using the inhibitor OSS_128167
Possible resultExpected TGFB1 silencing while SPM-driven IL-10/Arg1 upregulation proceeds
