LFNG and asthma: The asthma/GSI group treated with Lfng did not show an additive effect compared with cells pretreated with GSI or treated with Lfng alone (Fig. 9), which meant that Lfng overexpression almost had the same effect as GSI blockage on Th2 cytokine promotion but had a greater effect on Th1 cytokines than GSI treatment.
