    <t>GDF15</t> expression in DCs. (A) A time course of GDF15 expression in DCs. DCs (10 6 cell/well) were cultured from bone marrow progenitors in the presence of IL-4 and granulocyte/macrophage colony stimulating factor (GM-CSF). Cultured DCs were collected on day 2, 4, 6, and 8 for RNA extraction. The level of GDF15 mRNA was detected by qRT-PCR and GAPDH was used as loading control. Relative quantity of GDF15 mRNA was the expression of GDF15 in Day 2 DCs. n = 4, One way ANOVA was conducted for statistical analysis. (B) rhGDF15 increased GDF15 expression in DCs. BM-derived DCs were cultured and a variety of concentrations of rhGDF15 were added on day 4. Twenty-four hours after treatment, GDF15 expression in DCs was detected using qRT-PCR. GDF15 expression was normalized with control DCs without rhGDF15 treatment. n = 4, One way ANOVA was conducted for statistical analysis. (C) The up-regulation of GDF15 in DCs by rhGDF15 was time related. BM-derived DCs were treated with 2.5 ng/ml rhGDF15 on day 5. n = 3, the student T -test was conducted for statistical analysis. GDF15 expression in DCs was detected 4 h and 12 h after addition of rhGDF15 by qRT-PCR. The expression of GDF15 in DCs treated for 4 h was used as a normalizer. (D) GDF15 protein expressed in DCs. Total protein was extracted from day 2 and 6 in vitro cultured DCs. GDF15 expression at the protein levels was determined by western blotting using GDF15 Abs. β-Actin was used as a loading control. Images were representatives of n = 3, * P < 0.05.

    GDF15 regulated DCs by using TGFβ receptors. (A) Expression of GFRAL and TGF-β RI and RII. RNA was extracted from DCs and the expression of GFRAL and TGF-β RI and RII was detected by RT-PCR. PCR products were run on 1.5% agarose gel and visualized with EB. (B) TGF-β receptor I and II reversed the inhibitory function of GDF15 in DC maturation. DCs cultured from WT mice and treated with rhGDF15 on day 4. Ly210976 (5 mg/ml) and Ly 364947 (10 mg/ml) was added to rhgDF15 treated DCs on day 5, respectively. 24 h later, DCs maturation was determined by measuring expression of MHCII, CD40, CD80, CD83, CD86, and CCR7 flow cytometry. Data were representatives of three independent experiments. (C) IP assays. Total protein was extracted from the above DCs treated with GDF15-Ad or control Adenovirus and an IP assay was employed to pull down GDF15 bound protein using GDF15 Abs and control Ig Abs. IP protein was subjected to western blotting with TGFβ RI and RII Abs respectively. Representative of image of n = 4 experiments. PCR products for TGF-β RII from Splenocytes (SP) and two DC samples (DC1 and DC 2) were loaded separately by other genes products on an agarose gel and the image shown was modified by deletion of other genes' bands between TGF-β RII's bands.

    GDF15 regulated DCs prevent allograft rejection in heart transplantation and augment tolerance induction and T cell exhaustion. (A) Allograft survival. Donor derived (C57BL/6) DCs were cultured and treated with GDF15-Ad or Null-Ad on day 2. 1 million day 7 DCs were i.v. injected into recipient BABL/c mice 7 days prior to heart transplantation. Allogeneic heart transplantation was conducted between C57BL/6 and BABL/c mice. Recipient mice daily received 1 g/kg rapamycin for 7 days from day 0 post transplantation. The cessation of heartbeat was defined as rejection. n = 6. (B) CD4 + CD25 + Foxp3 + Tregs in splenic cells. At the end of experiments, mice splenic cells were isolated from recipient mice on day 100 to detect CD4 + CD25 + Foxp3 + Tregs by flow cytometry. Representative images (upper) and relative quantity of FoxP3 protein from n = 3 * P < 0.05. (C) Inhibitory receptor expression. RNA was extracted from the above rejected and tolerant recipient mice. Gene expression of inhibitory receptors PD-1, TIM3, BTLA and galectin 9 was detected by qRT-PCR. n = 3, the student t -test was conducted for statistical analysis * P < 0.05.
