TNF and infection: Considering that miR-130a-3p, miR-146a, miR-181a, miR-181b, miR-301a-3p, and miR-351-5p might participate in the negative regulation of TNF-α production in Omp25-expressing cells, we measured the expression of these miRNAs in PAMs and mouse RAW264.7 cells after LV-Omp25 infection.
