Webb15 dec. 2024 · Using murine allo-HSCT models, we show that pharmacologic Janus kinase 1/2 (JAK1/2) inhibition combined with CD45- or cKit-targeted ADCs enables robust multilineage alloengraftment. Strikingly, myeloid lineage donor chimerism exceeding 99% was achievable in fully MHC-mismatched HSCT using this approach. Webb14 dec. 2024 · We used a fully MHC-mismatched (BALB/c (H-2k d) → C57BL/6 (H-2 kb) murine models (Fig. 3a). There were no differences in weight loss among the groups, while the animals treated with the combination had lower clinical scores than the control and MSC- or Treg-alone treated animals (Fig. 3 b).
