Article Synopsis
  • Innate immune responses help control SARS-CoV-2 replication, and a specific lactic acid bacteria strain, Lactococcus lactis strain Plasma (LC-Plasma), can activate immune cells called plasmacytoid dendritic cells (pDCs).
  • Research showed that when pDCs are stimulated with LC-Plasma, their secretions can reduce SARS-CoV-2 replication in cell cultures.
  • The study also found that the secretion of interferon-α (IFN-α) from pDCs is crucial to this suppression; blocking IFN-α decreased the effectiveness of LC-Plasma in reducing the virus's replication.

KW3110 (KW3110) has anti-inflammatory effects, including the prevention of blue light exposure induced retinal inflammation and ageing-related chronic inflammation in mice. The mechanism involves the promotion of anti-inflammatory cytokine interleukin (IL)-10 production by KW3110, leading to reduced pro-inflammatory cytokine IL-1β production. Although various stress-induced mitochondrial damages are associated with excessive inflammatory responses, the effect of KW3110 on inflammatory-stress-induced mitochondrial damage remains unknown.

A strain of lactic acid bacteria, Lactobacillus paracasei KW3110 (KW3110), activates M2 macrophages with anti-inflammatory reactions and mitigates aging-related chronic inflammation and blue-light exposure-induced retinal inflammation in mice. However, the mechanism underlying the anti-inflammatory effects of KW3110 remains unclear. In this study, we investigated the anti-inflammatory effects of KW3110 using both mouse and human immune cells and evaluated the suppressive effect of KW3110 on the inflammatory reactions of the cells stimulated with lipopolysaccharide and adenosine 5'-triphosphate (LPS/ATP).

KW3110 (KW3110) has anti-inflammatory effects and mitigates retinal pigment epithelium (RPE) cell damage caused by blue-light exposure. We investigated whether KW3110 suppresses chronic inflammatory stress-induced RPE cell damage by modulating immune cell activity and whether it improves ocular disorders in healthy humans. First, we showed that KW3110 treatment of mouse macrophages (J774A.
