ABSTRACT
PURPOSE:
This study investigated interleukin (IL)-17-secreting cell involvement in sterile inflammation, and evaluated the effect of mesenchymal stem cells (MSCs) on IL-17-secreting cell immunologic profiling.METHODS:
Twenty mice were sacrificed at time points of 6 hours, 1 day, 1 week, and 3 weeks (each group, n = 5) after the cornea was chemically injured with 0.5N NaOH; IL-17 changes in the cornea were evaluated using enzyme-linked immunosorbent assay. Further, IL-17 secreting cells were assessed in the cervical lymph nodes by a flow cytometer. Rat MSCs were applied intraperitoneally in a burn model (n = 10), IL-17-secreting T helper 17 (Th17) cell and non-Th17 cell changes were checked using a flow cytometer in both cornea and cervical lymph nodes at 1week, and compared with those in the positive control (n = 10).RESULTS:
IL-17 was highest in the cornea at 1 week, while, in the cervical lymph nodes, IL-17-secreting cells showed early increase at 6 hours, and maintained the increase through 1 day to 1 week, and levels returned to the basal level at 3 weeks. Specifically, the non-Th17 cells secreted IL-17 earlier than the Th17 cells. When the MSCs were applied, IL-17 secretion was reduced in CD3(+)CD4(-)CD8(-), CD3(+)CD4(+)CD8(-), and CD3(+) CD4(-)CD8(+) cells of the cervical lymph nodes by 53.7%, 43.8%, and 50.8%, respectively. However, in the cornea, IL-17 secretion of CD3(+)CD4(-)CD8(-) cells was completely blocked.CONCLUSIONS:
The results indicated that both IL-17-secreting non-Th17 and Th17 cells were involved in the chemical burn model, and MSCs appeared to mainly modulate non-Th17 cells and also partially suppress the Th17 cells.Key words
