Asthma is characterized by inflammation of the airways, including the inflammatory and airway structural cells. Probiotics, which have diverse effects, even within the same species, are being studied to prevent and mitigate the severity of asthma. Lactilactobacillus sakei WB2305 and Lactiplantibacillus plantarum WB2324 were isolated from kimchi. These strains have acceptable probiotic properties and are safe. In addition, the anti-inflammatory potential of the heat-killed isolates against lipopolysaccharide (LPS)-induced inflammation in the human pulmonary epithelial cell line (A549) was investigated. The heat-killed Lact. sakei WB2305 and Lact. plantarum WB2324 reduced the chemokine and cytokines mRNA expression levels, as shown by the results of using real-time polymerase chain reaction. Western blotting results showed that the nuclear factor-kappa B (NF-κB) activation and mitogen-activated protein kinases (MAPK) signaling pathways were suppressed by treatment with the heat-killed strains. The production amounts of eotaxin, tumor necrosis factor-ɑ (TNF-α), and interleukin-6 (IL-6) were lower than those in LPS-only treated cells. Additionally, 2',7'-dichlorofluorescein diacetate (DCFH-DA) staining confirmed decreased reactive oxygen species (ROS) production in A549 cells. Therefore, the results of present study demonstrate the anti-inflammatory and anti-asthmatic activities of heat-killed Lact. sakei WB2305 and Lact. plantarum WB2324 in human airway epithelial cells.
