Cross-linking of endogenous mLMIR5 induced the activation of FLMCs. (A) WT or Syk-deficient FLMCs were stimulated with control IgG or anti-mLMIR5 Ab. The amount of phosphorylated ERK1/2 was measured as described. (B,C) IL-6 production (B) and percentage of adherent cells (C) were analyzed as described. All data points correspond to the mean and the SD of 4 independent experiments. Statistically significant differences are shown. *P < .05.
