To generate the CD11c-Cre transgene, the 160-kb mouse genomic BAC clone RP24-361C4 (BACPAC Resources) was modified by ET recombination, as previously described (43 (link)). The clone contains the entire Itgax (CD11c) gene but lacks the 5′ end of the adjacent Itgam (CD11b) gene, preventing the overexpression of the latter. The recombination cassette containing the Cre recombinase open reading frame, followed by the bovine growth hormone (BGH) polyA signal and the FRT site-flanked prokaryotic Zeocin resistance cassette (ZeoR), replaced the coding part of the first CD11c exon, and the ZeoR cassette was subsequently removed by FLP-mediated recombination. The clone insert was released from the vector backbone using NotI digestion, gel-purified, and microinjected into fertilized oocytes. The founder line containing two copies of the transgene (as determined by quantitative Southern hybridization) was chosen for further analysis. Mice were genotyped by genomic PCR using either generic Cre primers or primers specific for the CD11c-Cre transgene (5′-ACTTGGCAGCTGTCTCCAAG-3′ and 5′-GCGAACATCTTCAGGTTCTG-3′ were specific for the CD11c promoter and Cre, respectively).
The R26-EYFP strain (21 (link)) was provided by F. Costantini (Columbia University, New York, NY). The RBP-Jfl strain (19 (link)) was provided by L. Hennighausen (National Institute of Diabetes and Digestive and Kidney Diseases, Bethesda, MD), with permission from T. Honjo (Kyoto University, Kyoto, Japan). The Mx1-Cre strain was previously described (44 (link)). Cre-negative RBP-Jfl/fl littermates of CKO (RBP-Jfl/fl Cre+) mice were used as controls; in preliminary experiments, wild-type CD11c-Cre+ mice were used as controls and were found indistinguishable from CD11c-Cre animals. For inducible RBP-J deletion, adult RBP-Jfl/fl Mx1-Cre+ or control RBP-Jfl/fl mice were injected with 0.25 mg poly(I):(C) three times, with 2-d intervals, and analyzed 3 wk later. For hematopoietic reconstitution, 3 × 106 total BM cells per mouse were injected i.v. into lethally irradiated C57BL/6 mice congenic for CD45.1. The recipient mice were analyzed 4–5 wk after reconstitution. Mice were maintained in a specific pathogen-free facility and used according to the protocol approved by the Columbia University's Institutional Animal Care and Use Committee.

The pFUSE-Fc plasmid (400 mg) was supplied by the Department of Pathology, Sapporo Medical University School of Medicine. The retroviral reprogramming plasmids pFUSE-hIgG1-Fc2 (InvivoGen, CA, U.S.A.) have been previously described (21 (link)). pFUSE-Fc2 (IL2ss) plasmids facilitate the secretion of Fc-Fusion proteins from pFUSE-Fc-transfected cells. To obtain single-chain Fc fragments of IgH and IgK, we followed the principle of PCR assembly (22 (link)), and the information of the inserted synthesized representative cDNA and the amplified primers are shown in Supplementary Table 1. Briefly, the plasmid was digested with EcoRV and NcoI (Takara Bio, Shiga, Japan), and the targeted IgH and IgK domains were obtained using a two-step overlapping PCR. The PCR product was subcloned into the digested plasmid using In-Fusion HD Cloning kits (Takara Bio); the In-Fusion reaction mixture was transformed into competent cells, and individual isolated colonies were picked from the culture plate. Plasmid DNA was isolated using a Plasmid DNA purification kit (Macherey-Nagel GmbH& Co.), and 2.5 μg of the DNA transfected into 293 T cells using Lipofectamine 3000 (Thermo Fisher Scientific, MS, U.S.A.). Subsequently, the 293 T cells were grown in Dulbecco’s Modified Eagle Medium containing 10% fetal bovine serum and 1% penicillin-streptomycin solution with zeocin (300 μg/mL, InvivoGen), and the supernatant was collected from the culture well on day 2 and days 7–10. IgGs from the supernatant were collected from 3–5 culture dishes and purified using a spin column-based antibody purification kit (Protein G; Cosmo Bio, Tokyo, Japan).

Ppddm1 was obtained through the replacement of the gene coding region with Zeocin resistance antibiotic cassette through homologous recombination. Homologous flanking 5’ (1068bp upstream to ATG site) and 3’ (252 bp upstream to stop site and 536bp downstream to stop site) were amplified using KOD polymerase (Sigma-Aldrich) and cloned into a PMBL5-Zeo vector. Integration of flanking regions was validated using PCR. Linearized plasmid was introduced to moss via PEG-mediated transformation protocol [43 (link)]. After three days, the regenerated protoplasts were transferred to the BCDAT medium. After seven days the moss was subjected to selection using Zeocin (25ng\μl). After three weeks, surviving plants were subjected to PCR to validate the correct integration of the construct into the genome and gene replacement. This was done through primers targeting the endogenous gene sequence and primers targeting regions flanking the 5’ and 3’ homologous regions and Zeocin resistance cassette.

The recombinant vectors of Anman and mutants were linearized by restriction endonuclease Sal al restriction endonuclease. The linear vector was transferred into P. pastoris X33 and incubated in yeast extract peptone dextrose (YPD) solid medium containing 100 mg/mL bleomycin (zeocin) at 30°C for 72 h. Colonies were picked and incubated in 30 Ml YPD liquid medium at 30°C and 220 rpm for 24 h, and cells were then collected by centrifugation at 8,000 rpm and transferred to 30 mL YP medium containing 0.5% methanol at 28°C and 220 rpm for 72 h. Methanol was added every 12 h to maintain its concentration at 0.5% for induction of enzyme production.
The induced fermentation broth was centrifuged at 4°C at 8,000 rpm, and the collected supernatant was dialyzed for 16 h in 0.1 M NaH2PO4-Na2HPO4 containing 20 mM NaCl (pH 5.5, buffer A) to remove salt and metal ions. Anion exchange chromatography was used for the purification of crude enzymes. Briefly, after pre-equilibrating the anion exchange column (Hi Trap™ 1 mL Q HP) with Buffer A, the dialyzed crude enzyme was loaded onto the column, followed by a linear gradient elution using Buffer A with Buffer B (Buffer A with 1 M NaCl), and the collection containing the enzyme activity was utilized for the subsequent study. The purification of the samples was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) (Laemmli, 1970 (link)). The Bradford method was used to determine the protein concentration (Bradford et al., 1976 (link)).
