接受Lewis同种异体移植的Fischer 344大鼠接受TNP-470治疗,TNP-470是一种合成的富马青霉素衍生物和一种成熟的血管生成抑制剂。与未治疗的受体相比,单独使用TNP-470可使移植物存活时间有所延长,但所有移植物最终都失败了。相比之下,从第0天到第30天使用环孢素(CsA)治疗可延长移植物存活时间,组织学上显示同种异体心脏移植物血管病变(CAV)明显(平均评分2.28±0.2)。CAV病变的内膜内有许多新生血管。第0 ~ 30天,TNP-470联合CsA治疗,CAV程度与单独CsA治疗相似(平均评分2.22±0.26)。然而,当停用CsA后第30天至120天给予TNP-470时,CAV程度明显降低(平均评分1.08±0.11)。因此,晚期给予TNP-470阻断CAV的进展,而移植后立即给予TNP-470则不能阻止其发展。
Fischer 344 rat recipients of Lewis allografts were treated with TNP-470, a synthetic fumagillin derivative and a well-established angiogenesis inhibitor. TNP-470 alone resulted in some prolongation of graft survival as compared with untreated recipients, but all grafts ultimately failed. In contrast, treatment with cyclosporine (CsA) from day 0 to 30 resulted in prolonged graft survival and marked cardiac allograft vasculopathy (CAV) by histology (mean score 2.28±0.2). There were many neovessels within the intima of CAV lesions. When TNP-470 was administered in combination with CsA from day 0 to 30, the degree of CAV was similar to that with CsA alone (mean score 2.22±0.26). However, when TNP-470 was administered from day 30 to 120 after discontinuation of CsA, there was a marked reduction in the degree of CAV (mean score 1.08±0.11). Therefore, TNP-470 interrupts the progression of CAV when given late but does not prevent its development when given immediately posttransplantation.
