MENK treatment upregulated opioid receptors (MOR and DOR). Lungs were collected on day 10 p.i. Gene expression levels of opioid receptors (MOR and DOR) were quantified by qPCR. Results are presented as fold increase relative to the NS group. The data represent the mean ± SD of three independent experiments (each performed with n = 6 mice).★p < 0.05, ★★p < 0.01 versus the PR8 group
