In good agreement with the UBC13-stabilizing function of OTUB1 in TgPFN-stimulated BMDCs (Fig. 3f), we detected the increased expression of UBC13 in CD8+ cDC1s, PDCA1+ DCs, and CD11b+ cDC2s isolated from OTUB1fl/fl mice after infection with T. gondii (Fig. 4b, first top panel), confirming the critical role of OTUB1 in stabilizing UBC13 in DCs in vivo. Here, CD8A is linked to infection.
