Abstract:
Objective: Interleukin-10 (IL-10) is an anti-inflammatory helper T cell type 2 (Th2) cytokine that modulates Th1-type cytokine production. The purpose of present study was to detect the expression and changes of IL-10 in the rats heart transplantation, as determine the role of IL-10 in the acute rejection of rats heart transplantation. Methods: Hearts from DA rats were transplanted into the necks of Wistar recipients. Allografts was divided into five groups: group A (control, n=12), group B (DST treated, n=12), group C (IL-2 Mab treated, n=12), group D (IL-4 Mab treated, n=12), group E (IL-2 Mab treated, n=12). The local expression of IL-10 was analyzed at day 1,3,5,7,9,11,14 by reversed transcripition polymerase chain reaction (RT-PCR). Results: Allografts survival time was (8.3±1.7) days, (29.2±7.1) days, (26.4±5.7) days, (10.2±1.9) days and (55.0±10.6) days (P＜0.05， P＜0.01), respectively. When compared with group A, the level of IL-10 was upregulated in group B, group C and group E, especially in group E. The upregulation of IL-10 was related to the grafts survival time. Conclusion: IL-10 plays an important role in the development of acute transplantational rejection, suggests that Th-2 type deviation may contribute to the prolongation of graft survival.
