miR-125b-5p, but not miR-99a-5p, regulates the secretion of IFN-γ and TNF-α in γδ T cells during cytotoxicity. (a and b) ELISA was performed to analyze the expression of IFN-γ (a and b) and TNF-α (c and d) in γδ T cells during the killing of Daudi cells at 24, 48 and 72 h after electroporation with the NC, miR125b-5p or miR-99a-5p mimics or inhibitors. Data are shown as the means±s.d. (n=3 independent experiments). *P<0.05, by paired Student’s t-test.
