Lipoteichoic acid upregulates NF-κB and proinflammatory cytokines by modulating β-catenin in bronchial epithelial cells

Lipoteichoic acid (LTA) is a major cell wall component and virulence factor of gram-positive bacteria. The present study investigated the LTA‑induced inflammatory response of BEAS‑2B human bronchial epithelial cells, and detected the expression levels of proinflammatory cytokines interleukin (IL)‑6, IL‑8, IL‑1β, tumour necrosis factor‑α and monocyte chemotactic protein‑1, the upregulation of NF‑κB, and the phosphorylation and degradation of...
