Owing to the biological changes in adipocytes in some metabolic diseases, allograft fat can provide a better source of donor fat than autologous fat. Fingolimod (FTY720) possesses a powerful immunomodulatory function. This study aimed to investigate the protective effect of FTY720 in allogeneic fat transplantation. C57BL\/6J mice that received allografts were randomly divided into two groups and treated with saline and FTY720, respectively. Fat graft samples were obtained at 1, 6, and 20\u2009weeks posttransplantation. Graft volumes, graft structure, and immune cells were estimated using histological examination, immunohistochemistry, staining immunofluorescence (IF), and quantitative real\u2010time polymerase chain reaction (qRT\u2010PCR). Inflammatory cytokine mRNA expression in grafts was detected by qRT\u2010PCR. FTY720 treatment significantly enhanced allograft retention, structural integrity, and neovascularization, thereby demonstrating the potential of FTY720 in improving graft survival. Further IF staining showed that FTY720 increased regulatory T cell infiltration and reduced macrophage infiltration to some extent. FTY720 treatment also enhanced the expression of the anti\u2010inflammatory cytokines interleukin (IL)\u20104 and IL\u201010 and weakened the expression of the pro\u2010inflammatory cytokines TNF\u2010\u03b1 and IL\u20106. Furthermore, FTY720 treatment upregulated the expression of CD31 positive cells. This study demonstrated the potential efficacy of FTY720 in improving the graft survival rate of syngeneic fat allograft models, possibly by suppressing immune rejection and promoting angiogenesis. Therefore, this study offers key insights into the potential application of a drug\u2010assisted strategy to prolong allograft fat survival.<\/jats:p>","DOI":"10.1002\/kjm2.12570","type":"journal-article","created":{"date-parts":[[2022,7,14]],"date-time":"2022-07-14T09:07:30Z","timestamp":1657789650000},"page":"889-896","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The
