- W4224254769 abstract "Purpose Effector and regulatory T cells (Tregs) are main cell populations in the context of cardiac allograft vasculopathy (CAV). The immunostimulant plerixafor mobilizes hematopoietic stem cells and may boost T cells. Therefore, the aim of this study was to evaluate if a single, repeated, or continous treatment with plerixafor increases peripheral bone marrow derived stem cells including Tregs leading to tolerance induction and thus reducing chronic rejection in a mouse allograft transplant model. Methods Fully allogeneic mouse aortas from C57BL/6 mice (H2b) were abdominally transplanted into CBA mice (H2k). The continuously plerixafor application [1mg/kg/d] was carried for 14 days using implanted small osmotic pumps. Single dose (s.c.) injection of 1mg/kg/d or 5mg/kg/d were done at day 1 after transplantation (Tx.) and pulsed injections [1mg/kg/d] were conducted on days 1, 7, 14, and 21 after Tx. The control allograft group received vehicle loaded osmotic pumps. Stem cell mobilization was monitored by FACS. Recipients were sacrificed on day 14 for intragraft gene expression analysis or on day 30 for histological measurements. Results Murine aortic grafts with pulsed plerixafor injections showed significantly reduced neointima proliferation compared to control allografts (33.65%±8.84% vs.53.13% ±12.41%; p<0.05). The single shot and continuous treatment groups exhibited no improvement concerning neointima formation. First FACS analysis revealed significantly less hematopoietic stem cells (HSC) in the bone marrow of plerixafor treated mice vs. the control at day 14 after Tx. There were significantly more HSCs in the peripheral blood on day 30 after Tx, with the pulsed injection even doubling HSCs [0.0152%±0.008; p<0.005 (pulsed); 0.0046%±0.002%; p<0.01 (pump); 0.0076%±0.001%; p<0.01 (single dose 1mg/kg); 0.0039%±0.0017%; p<0.1 (single dose 5mg/kg) vs. 0.0018%±0.0016% (control)]. Preliminary intragraft gene expression results showed clearly reduced IFNγ expression and a significantly increase of IL-4, IL-10 and TGFβ. Conclusion These data suggest that both the continued and injected application of plerixafor leads to potent stem cell mobilization and hereby the repeated treatment with plerixafor reduces neointima formation in a mouse aortic transplant model.
