A higher-dose anti-CD25 regimen without methotrexate lowered acute GVHD rates and improved survival in patients undergoing haploidentical transplant.

We’re hoping for big things from Arcam’s step-up CD player – can it deliver?

To investigate whether human Treg cells are susceptible to losing lineage identity, CD4+CD25+CD127lo/− fluorescence-activated cell sorting (FACS)-isolated primary human Treg cells (Extended Data Fig. 1a) were subjected to repeated cycles of in vitro CD3/CD28 stimulation in the presence or absence of proinflammatory cytokines (Fig. 1a). As a preliminary gauge of Treg cell identity, we focused on FOXP3 and HELIOS, a key pair of TFs with well-established, complementary roles in regulating Treg cell fitness and suppressive function13,14 (Extended Data Fig. 1b). As human conventional CD4+ T (Tconv) cells transiently express FOXP3 following T cell receptor (TCR) activation, expression profiles were evaluated 7 days into each stimulation cycle, after FOXP3 levels had mostly waned in non-Treg cells15. Previous studies on the impact of inflammatory cytokines on human Treg cell lineage stability have implicated a negative role of IL-1214,16, whereas the effects of IL-6 have been more controversial17,18,19,20. We thus started with unbiased comparisons of Th1-, Th2- and Th17-driving cytokines, singly and in combinations (Extended Data Fig. 1c). We found that the Th17-promoting combination of IL-6, IL-1β and IL-23 was the most consistent at inducing FOXP3 and HELIOS silencing (Extended Data Fig. 1c). The extent of Treg cell destabilization by this triple cytokine...
