doi: 10.3389/fimmu.2022.852427

Figure Lengend Snippet: T-cell development from Notch2 -deficient BM cells in the thymus of iD4 and iD1 mice. Age-matched control (WT) or Notch2 -deficient (N2KO) BM cells were obtained from Notch2 f/f or Rosa26 CreERT2 Notch2 f/f mice (CD45.1) 1 week after the administration of tamoxifen. BM chimeric mice were prepared in irradiated (6 Gy) C57 BL/6 mice (CD45.2) with Notch2 -deficient BM and analyzed 4 weeks after the reconstitution ( Supplementary Figure 3A ). (A) Flow cytometric analysis was performed using the thymocytes from BM chimeric mice with control (WT) or Notch2 -deficient (N2KO) BM cells ( Donor ) in Dll4 f/f (Cont), Dll4 f/f FoxN1-Cre (D4KO), iD4 Dll4 f/f FoxN1-Cre (iD4/D4KO), or iD1 Dll4 f/f FoxN1-Cre (iD1/D4KO) mice as the recipients ( Recipient ). Numbers in the profiles indicate the relative percentages, in CD45.1 + cells (left panels, CD19 vs. Thy1.2) and CD45.1 + Thy1.2 + cells (right panels, CD4 vs. CD8), for each quadrant or fractions.

doi: 10.3389/fimmu.2022.852427

Figure Lengend Snippet: T-cell development from Notch1 -deficient BM cells in the thymus of iD4 and iD1 mice. The primary BM chimeras were prepared in irradiated WT (CD45.2) mice with BM cells from Notch1 f/f (WT, CD45.1) or Rosa26 CreERT2 Notch1 f/f (N1KO, CD45.1) mice and GFP Tg mice. The control and Notch1 -deficient BM cells were obtained from the primary BM chimeras after the administration of tamoxifen and serially transferred into Dll4 f/f (Cont), Dll4 f/f FoxN1-Cre (D4KO), iD4 Dll4 f/f FoxN1-Cre (iD4/D4KO), or iD1 Dll4 f/f FoxN1-Cre (iD1/D4KO) mice. Four weeks after the reconstitution, thymocytes were analyzed ( Supplementary Figure 3B ). (A) Flow cytometric analysis was performed using the thymocytes from the secondary BM chimeric mice. Numbers in the profiles indicate the relative percentages, in CD45.1 + or GFP + cells (internal control, Int. cont) (left panels, CD19 vs. Thy1.2) and CD45.1 + Thy1.2 + or GFP + Thy1.2 + cells (right panels, CD4 vs. CD8), for each quadrant or fractions. Results represent at least three independent biological replicates. (B) The efficiencies of the appearance of CD4 + CD8 + (DP) thymocytes derived from control (WT) or Notch1 -deficient (N1KO) BM cells were examined. DP appearance index was calculated as the ratio of CD45.1 + /GFP + DP thymocytes and CD45.1 + /GFP + B220 + B cells in lymph node (mean ± SD; WT as donor; Cont, n=3; D4KO, n=3; iD4/D4KO, n=3; iD1/D4KO, n=4; N1KO as donor; Cont, n=5; D4KO, n=5; iD4/D4KO, n=5; iD1/D4KO, n=5). The data were collected from three independent experiments. Each closed circle indicates the index in each mouse. **p < 0.01, ***p < 0.001 by Mann–Whitney U -test.

doi: 10.2147/JIR.S336964

Figure Lengend Snippet: Changes in the proportion of immune cells in myocardial tissue were analysed via flow cytometry. ( A ) The proportion of CD45 + cells in each group was detected by flow cytometry. ( B ) The proportion of CD45 + CD11b + cells in each group was detected by flow cytometry. ( C ) The proportion of CD68 + CD86 + cells in each group was detected by flow cytometry. ( D ) Pulmonary hypertension and LPS caused a significant increase in the proportion of CD45-positive inflammatory cells in right ventricular tissue (normal vs PAH, normal vs normal + LPS, n = 3). ( E ) CD45-positive/CD11b-positive mononuclear macrophage infiltration was significantly elevated in right ventricular tissues from rats subjected to PAH or LPS (normal vs PAH, normal vs normal + LPS, normal + LPS vs PAH + LPS, n = 3). ( F ) The proportion of CD68-positive/CD86-positive M1 macrophages was decreased in the hearts of PAH rats and significantly increased in the right ventricular tissues of PAH rats stimulated with LPS, but MCC950 application significantly inhibited the change in the proportion of CD68-positive/CD86-positive M1 macrophages (n = 3). The significance of the difference was analysed by one-way ANOVA, **p < 0.01, ***p < 0.001, ****p < 0.0001.
