These results suggested that IL-17A-mediated alleviation of cortical astrocyte ischemic injuries could affect the neurological outcome of mice with ischemic stroke, which might be mainly dependent on the cell apoptosis pathway through inhibiting the downregulation of IL-17RA and -17RC membrane translocations.
A significant reduction in proportion of peripheral Treg cell frequency and the levels of TGF-β and FOXP3 expression were observed in patients with IS compared with controls, while the proportions of Th17 were increased dramatically, and these effects were along with increases in the levels of IL-17A and RORγt expression in IS patients.
Individuals carrying rs2275913 GA or GG genotype present higher serum IL-17A levels compared with the rs2275913AA genotype in the IS group (<i>P</i><0.01).
In this prospective study we evaluated numbers of peripheral blood mononuclear cells (PBMC) expressing mRNA for interleukin (IL)-1beta, IL-8, and IL-17 and macrophage inflammatory protein-1alpha (MIP-1alpha) after ischemic stroke.
